Why is gasoline flies out of the exhaust pipe at a trimmer for grass

Before resorting to more serious repair actions, you must make sure that the graduation channel is serviceable. This section does not apply to previously not used trimmers, since they have practically no production. If the lawn mower is operated for many years and during this time the unit was not subject to serious diagnostic measures, then it is necessary to check the fact of the clogging of the muffler.

The accumulation of soot prevents the exhaust gases from going out, which is why it is simply impossible to start the engine. Of course, on one day the graduation channel cannot clog, which is why such a situation should be preceded by certain signs. The exit of black smoke from a silencer is a kind of incapacity, which gradually accumulates on the walls of the exhaust system. A significant increase in the sound of the installed motor may occur, which is associated with overcoming huge resistance with exhaust gases to release them. When working at idle, the device stalls spontaneously. In critical situations, the engine operation is significantly deteriorated.

If there are serious pollution on the anti.skill net, then the reason for the impossibility of starting a trimmer engine may be precisely in the exhaust channel. You need to clean the mesh as carefully as possible, since it is the black cargo that is a carcinogen that is very dangerous for a person, which can provoke damage to the respiratory tract. For cleaning, specialized tools should be used that will cope with the soil.

The most characteristic reasons, methods for eliminating

NOTE! When the carburetor of the 2107 ozone shifts, it is necessary to first check the adjustments and settings of the first and second float chamber.

How to rinse a gasopyle carburetor?

To clean the node from strong contaminants, it is best to use a tool that is delivered on sale in cylinders under pressure. Included with the cleaner, there is a dispenser and a long thin tube, which makes it possible to spray the product in any inaccessible places.

It must be remembered that cleaning the carburetor on the chainsaw is performed using flammable chemicals. You need to work with them in a special protective mask and only in well.ventilated rooms.

To clean the carburetor on the chainsaw, the knot will need to be partially disassembled. Throttle, adjusting screws, housing and other parts of the carburetor will need to be washed with a core with a cylinder and postponed until completely dry. As soon as all the elements dry, the node can be assembled and installed back on the chainsaw.

How a two.stroke engine works: briefly, but it is important to know for a clear launch of a lawn mower

Lawn mowers are produced with two.stroke or four.stroke internal combustion engines. The difference in the design is significant, but each model starts on the general principle. I show on the example of the Chinese trimmer for Eco grass.

The engine is called two.stroke because the full.time cycle is two tacts: the stroke of the piston from the upper dead point of the VMT to the lower NMT. In this case, the launch occurs with the second achievement of the upper position.

trimmer, grass, does, start

Similarly, chainsaws, boat engines and gasoline tools of another similar technique work. Consider the procedure. We are supposed to figure it out.

To start a trimmer motor for grass, we pull the starter’s cord. Its stretching is spinning a crankshaft with a flywheel creating the moment of inertia. The rotation of the crankshaft shaft is converted into the reciprocating movement of the piston.

The two.stroke motor has 4 working cycles:

  • The first movement of the piston from the VMT to the NMT is accompanied by the injection of the fuel mixture (gasoline with butter and air), when the carburetor inlet valve opens under the influence of the created vacuum;
  • The movement of the piston from NMT to the VMT: the intake and exhaust valves are closed, and the working mixture is compressed in a sealed volume;
  • Both valves remain closed. At the upper dead point of the piston through the contacts, the spark slides through the contacts.There is an explosion of compressed gases. Its strength with an impulse throws the piston down and rotates the crankshaft through the connecting rod;
  • The force of inertia of the flywheel directs the piston from the NMT up: the exhaust valve opens and through it the combustion products are pushed into the exhaust pipe.

How To Clean a Clogged Carburetor on a 2 Cycle/2 Stroke Engine (Weed Eater, Chainsaw, Blower, etc.)

All stages are performed automatically, but they are prepared by a person with his actions. When making errors it is made, the benzotrimer does not start and may break.

I try to make out all these points in more detail.

Cycle: what mistakes of beginners lead to breakdown of the engine of the trimmer for grass and exclude its normal operation

6 common mistakes with fuel

The manufacturer in the instructions clearly indicates the brand of gasoline with an octane number, oil and their proportions.

The first three errors are that the user of motorcycles violates all or one of these requirements. The motor will most likely start and work, but its resource may decrease sharply.

A small amount of oil, like its absence, will lead to the fact that the walls of the cylinder will not grease normally, and the piston rings will scratch them, and not slide.

Excess oil will simply burn, forming soot. She will pollute everything, including the piston and cylinder.

Failure gets into the valve, blocks their work, after which the motor will not start.

Will have to disassemble and clean the carburetor, or even put a new. Of course, you can try to wash the piston and the cylinder: it may be possible to bring them into working condition, but it is better not to bring them to.

The fuel mixture must be prepared with high quality and in strict proportion. The repair of a spoiled engine is expensive, about 70% of the price for a new gasoline trimmer for grass.

For the preparation of high.quality fuel mixture, I have a special container with a factory division of divisions in a set of trimmer for grass. Gasoline is neatly poured into it to the level of 500 ml, and then the oil to the required label.

An alternative method is the preparation of a fuel mixture with filling gasoline into a calibrated container, for example, a liter canister or a plastic bottle to a label, and an oil additive with a medical syringe according to its divisions.

The dosage with a syringe is more convenient, is considered the most popular way.

I recommend filling gasoline through a funnel with a narrow neck that has a filter: a metal mesh. protection against small garbage.

The prepared mixture should be well shaken and mixed until a uniform color appears. Only after that it can be poured into the tank.

If the mixture does not blame, then it will remain in the tank, and through the carburetor will enter the combustion chamber in portions with different ratios of gasoline and oil.

trimmer, grass, does, start

Fractions of clots of oil clog a candle. The motor stops, stalls, does not start. This is the fourth mistake of beginners.

It should be borne in mind that gasoline is hazardous. The risk of fire exists. Therefore, it is necessary to fill the mixture at a safe distance from the buildings, and in the case of the strait, which often happens to eliminate the causes of a possible fire. Violation of fire fighting measures. error

After pouring the fuel into the gas tank, the latter closes with a screw plug and the lack of leaks is checked. The trimmer for the grass is raised up so that the gasoline fills the cork. There should be no subterations from under the lid or from the fuel hoses.

Lack of such a check. an error can cause a fire.

There is one technical cunning that can cause a benzotrimer motor is not started due to the cessation of fuel supply. If you look carefully at the center of the traffic jam, then a round hole is clearly visible.

We turned Motokosa. Gasoline filled the cork, but does not flow through the hole: there is a sapphone inside. He is working.

On the inside, its design is clearly visible: a valve system of plastic and rubber is built.

In the usual state, the valve is pressed to the hole and the fuel does not flow. Когда бензомотор работает, то топливная смесь расходуется через карбюратор. A vacuum is created in the tank. The vacuum opens the valve of the saapon, the pressure is restored.

You should know the two consequences of a malfunction of the sapuna:

  • Constantly open hole. fuel pours out of the tank during its inclinations (excess consumption and the probability of fire).
  • Contamination or sticking of the valve channel is the reason that the lawn mower does not start or stalls.

Check the soundtress is easy: you need to blow it in both directions.

All about the gas tank cover, including the repair of the saapun, is shown in the video of Bogdan Shabanov.

3 additional advice associated with limited chemical resistance of a mixture of gasoline with oil:

  • Do not create an excessive fuel supply. Use freshly prepared fuel mixture. In a maximum of a couple of weeks, she will lose her useful qualities;
  • Prepare as much fuel as it will go to one mowing during the day. At the end of the work, drain the rest from the gas tank and burn the last drops from the fuel canal with a neglected engine;
  • It is especially dangerous to leave the mixture in the gas tank for a long time. winter. In the spring, you will make sure that the engine does not start without cleaning the carburetor (gasoline evaporated, the oil thickened and glued the valve).

In more detail, the technology for eliminating these malfunctions shows in its video video “Chinese lawn mower is not started” Sergey Lesnik. Pay attention to the fuel filter.

To adjust the work of the carburetor allows a special screw, but it is not worth it to twist it without need: the factory adjustment is accurately exhibited. It is better for novice users to contact the service center.

Why is a trimmer not starting for grass (gasoline)?

Why is a trimmer not starting for grass (gasoline)?

Because he worked his. Why, this question may be as many answers. Poor fuel is far from an argument. Maybe a person does not know how to use it, so it starts not correctly. The fuel does not come, the candle is pierced, the wires are pierced, it does not turn on, does not know how to use it, the trimmer for the grass burned/broken, but there are still any other reasons can be. There are still such hooks.

The reasons why the gasoline trimmer for grass does not start can be several.

If the trimmer for the grass does not start or immediately stalls after the launch, then the problem may be in the fuel tank (namely as fuel), in the candle and the ultimate channel, in the air or fuel filter, in the saapon or the exhaust channel.

one). Be sure to check for the grass before starting a trimmer for grass, and most importantly and the quality of the fuel mixture.

2). A trimmer for grass may not start or stall with a flooded candle. It will need to be twisted and wiped.

Dry the channel candle for at least 3040 minutes. Otherwise, a new candle can also burst.

3). If a trimmer for grass starts without an air filter, then it is better to change the old filter for a new.

four). A trimmer for grass may not be started if the fuel filter is polluted.

5). Also, a trimmer for grass may be started due.

trimmer, grass, does, start

Also, the reason may be in the flow of dirt into the exhaust channel or clogging the muffle grid.

How to Replace Fuel Lines on Two Cycle/Two Stroke Engines

A gasoline trimmer for grass may stop starting for several reasons at the same time.

Firstly: try to clean the carburetor-its pollution leads to a breakdown of a gas station.

Secondly: vacuum may form in the barrel. If so, try to make a small click in the barrel lid.

Thirdly: roll the correct settings of the trimmer for the grass.

There are several reasons, as a result of which the trimmer for the grass will not start. I will list the main:

  • Poor fuel. For each model of a trimmer for grass you need gasoline with a specific octane number. Roll up with the operating instructions and make sure that you fill in the required.
  • flooded candles. At the same time, I advise you to check the candles for performance. Sometimes even new (in the box) candles can be inoperative or defective.
  • The fuel mixture does not enter the carburetor. Skip it a little.
  • The ignition coil failed.
  • The muffler is clogged. You need to free it from the haze. To do this, carefully disassemble and clean (can be burned on a gas burner).

Typically, the trimmer for the grass did not start after winter and we used to carry almost every spring a trimmer for grass to the workshop, where we were repaired. But, once, a knowledgeable person advised us in.the first, never leave gasoline in trimmer for the winter, because old gasoline may be the reason that the trimmer for the grass will not start, and he also said that the trimmer for the grass for the grass is necessary for the carburetor.fuel mixture. After we began to comply with these rules, our problems with the trimmer disappeared.

First of all, you can see the candle. If necessary, replace it, making sure that the candle is not broken and gives a normal spark. The next problem will be hidden in the fuel system. As mentioned above, check the tightness, then check the fuel filter, if necessary, change. Clean the carburetor, watch the effect. It will be necessary to delve into the ignition system, configure. To check the fuel system, you can pour several grams directly into the cylinder through the candles of the candle, screw the candle and try to start. At least a trimmer for the grass should make the sounds of a running engine within 1-2 seconds and a little smoke should fly out of the silencer.

This is interesting: how to reduce fuel consumption

If you do not start a trimmer for grass at all or immediately stalls after the start of the start, then you first need to look for the reason in the main nodes and units, for this you need to carry out the test in the following sequence, so this sequence: this sequence: this sequence: this sequence:

In these nodes, the whole problem may be consistent.

Useful material from which you will learn how to get a capricious gasoline trimmer for grass that does not want to work!

The summer time has come, and in the personal plots habitually hidden the lawn mower. Great tool, powerful and mobile. Using a gasoline trimmer for grass and grass, you can mow, and get rid of a dried.up weed. However, there are cases that the lawn mower does not start, works with interruptions or without developing full power. Of course, no one is at work! And as they say, you twitch the laborer’s handle more than the mowing.

Difficulties with the launch do not only have the types of motorcycle, but also in new. How to be in this situation? There is only one way out. to listen to the advice of experts and take advantage of their practical experience!

The lawn mower is not started: the reasons and methods of elimination

Diagnosis of the reasons why the lawn mower is not started. A quick return to the life of Chinese and domestic motorcycles with a two.stroke internal combustion engine.

It happens that a two.stroke motor does not even show flashes in the cylinder, but it happens. grabs, and then stalls. Do not be sad, this Chinese consumer goods can be repaired directly on the knee using a minimum of tools.

Before starting diagnostics, you need to make sure that the engine rotates with a slight resistance. If there is no compression in it, then the further is useless, and you need to change the piston (this is also nothing complicated, everything is as a designer).

Not starting on a cold trimmer for grass. we eliminate the cause

The trimmer for the grass does not start on the cold. The reason is an air leak that does not allow fuel to download. The gasoline trimmer does not start for grass still does not start, Cadet CC 98 b video trimmer for grass. In the camera.

The second reason why the garden tool does not work is the fuel ended. On Elinech T750, a fuel tank is located near the motor, but on most trimmers it is there. We unscrew the cap from the tank and pour gasoline there (the most optimal version of the AI-92, it is inexpensive and does not clog the carburetor as AI-76). Do not forget to add special oil for engines to the tank, 50 grams on the gas tank is enough, without it the motor will begin to “sneeze” and quickly become unusable. After cover the tank with a cap, wipe the surface of a trimmer for grass with a dry rag and our hands. A trimmer for Hitachi grass is not started. Repair, tool, regardless of their small dimensions. We also make the above manipulations to include a garden tool.

The owner of the summer cottage can not do without a lawn mower or. But in the process of its operation, situations may arise when this unit for some reason stops starting up. And there can be many reasons for this. Let’s find out why the gasoline trimmer for grass does not start.

Why is a trimmer not starting for grass. the reasons

To determine why the gasoline trimmer for grass is poorly started or stalls constantly, it is necessary to sequentially check the operation of all the main units of the unit

It is especially important to do this after a long.term storage of a lawn mower. So, the main reasons for such a trimmer’s behavior for the grass are as follows:

  • The culprit that the lawn mower is not started, there may be a poor-quality oil-Benzine fuel mixture. It must be prepared strictly according to the instructions. The savings here are not at all appropriate, since it can lead to the failure of the entire piston group of a trimmer for grass. Do not cook too much fuel mixture, as excess gasoline will lose their qualities over time.
  • You should know that gasoline trimmers for grass of stamps such as STIHL, Husgvarna and some others do not start if they are filled with cheap gasoline with a small octane number. Therefore, for such units, it is necessary to use only high.quality high.octane fuel.
  • If the trimmer for the grass stalls immediately during the start, then perhaps he has a candle flooded. In this case, it is necessary to twist it and dry it well for half an hour. Then drain the excess fuel that is in the chamber, clean the candle from the carbon fiber, put it in place and try to start the lawn mower.
  • If your new gasoline trimmer for grass does not start, there may be a lack of a spark. And this happens because the nest, where the candle is located, is dry and fuel does not light up. Should be slightly moisturized with a few drops of gasoline threaded connection of the candle.
  • A gasoline trimmer for grass can stall due to clogging of air or fuel filters. It is best to replace such elements with new.
  • The graduation canal and sapun can also clog. Cleaning these elements of the trimmer for the grass, it will be possible to start the unit without any problems.
  • Another reason why the gasoline trimmer does not start for grass, even when there is a spark, there may be a clogging of a carburetor. To clean the channels and nozzles, it is necessary to blow them with compressed air using a compressor. You can use to clean the carburetor and special washing.
  • If the gaskets of the carburetor are worn out, you need to change them. And in case of violation of the tightness of this device, you will have to determine the faulty part of the carburetor and replace it.
  • A trimmer for grass may not be launched due to wear of the piston group. However, it is better to change such parts of the lawn mower in the service center.

Why is a trimmer not starting for grass gasoline? Reasons and their elimination

In the near future, the gasoline trimmer for the grass got the status of the 1st of the main tools in the arsenal of summer residents. And this is logical, because a motorized braid for grass allows you to quickly put a personal plot in order. But from time to time it happens that a trimmer for grass does not start on a hot and even cool. In such situations, it is necessary without the help of others to establish the cause of the malfunction. Let’s find out what to do if a trimmer does not start for grass. The prerequisites, which more often lead to such troubles, will be considered further.

Checking the fuel mixture

Suppose you don’t start a trimmer for grass. In this case, the first thing is to check whether the fuel is enough in the tank, as well as evaluate the quality of the fuel mixture. To refuel a motorized unit, it is necessary exclusively high.quality gasoline. It is recommended to use fuel, the brand of which is not lower than AI-95. Refueling a trimmer for grass with fuel of unknown origin, not bought at a gas station, is fraught with frequent failures in the work of the tool. This can cause a breakdown of the cylinder-piston system. Repair in this case often exceeds the cost of the device itself.

Why is a trimmer not starting for grass gasoline? Incorrect preparation of the fuel mixture may also lead to this, which consists of oil and gasoline. The proportions in which the specified components are connected are indicated by manufacturers in the guide for the operation of a trimmer for grass. Preparing the fuel mixture is extremely not recommended in large volumes, that is, for the future. Indeed, with prolonged savings, there is a loss of the determining properties of the substance. Therefore, if a trimmer for grass does not start, it is worth draining the old fuel and use freshly prepared fuel mixture.

The trimmer for the grass is very hot

Overheating of a trimmer for grass can occur for many reasons:

  • Gasoline has not the same octane number indicated in the instructions for the unit;
  • the proportions of gasoline and oil during the preparation of the fuel mixture are not observed;
  • A mixture of fuel with butter has long been prepared (the mixture cannot be stored for more than 2 weeks);
  • The trimmer for the grass works more than the time instructions;
  • A low.power trimmer for grass on thick and hard grass is used, the device works with overload and quickly heats up;
  • shifted towards the bar or the cassette lid clutched.

The latter happens if you install the mowing head inappropriate for this unit

, or when the axis shifts inside the bar. These changes make it difficult to rotate, the load on the engine increases, and it overheating.

Determination of the causes of the malfunction

If the trimmer engine for grass does not start or stalls immediately after starting, when overheating or during the functioning of the device, extraneous noises are heard and vibration is clearly felt, it is important to perform a visual inspection and identify a non.working node

To optimize preparatory measures before repairing, a simple diagnosis should be carried out and checked in stages:

  • the presence of fuel in the tank and lubrication in the main nodes;
  • serviceability of the spark plug and its performance;
  • the purity of the fuel and air filter motorcycles;
  • Cutting of the exhaust channel and the device’s saepun;
  • The quality of the used fuel and lubricants.

To determine the functional performance of the ignition of the lawn mower, you should determine whether the candle works by testing the appearance of a spark in contact with the body of the functional device.

The spark plug itself can be changed to a new one, after driving the candle canal, if necessary, the old element is also dried, cleaned with special devices and returned to place.

Carburetor problems DAAZ 2107

The design of the carburetor has many small details, each of which is of great importance, since it performs a certain job. If at least one of the elements fails, the stable operation of the node is violated. Quite often problems arise when starting an unheated engine or at the time of acceleration. The carburetor is considered faulty in the manifestation of the following signs:

  • When working on the twentieth, the engine works with failures, t. e. unstable;
  • When trying to accelerate, some delay is observed;
  • increased fuel consumption;
  • difficult to launch the motor after prolonged downtime.

Each of these signs indicates the need for repair or adjustment work. Consider the most common malfunctions of the “seed” carburetor.

Adjustment of xx

The most significant reason for which you have to adjust the idle passage of the carburetor is when the engine is unstable for xx, while the tachometer arrow constantly changes its position. As a result of the power unit, it simply stalls. By a flat screwdriver, we proceed to the adjustment:

Where to start diagnostics motorcycles

If the lawn mower does not start or immediately stalls after starting, it is necessary to sequentially check all the main nodes and assemblies. The test algorithm is as follows:

  • Fuel tank (fuel quality);
  • Candle and candle channel;
  • Air filter;
  • Fuel filter;
  • Breather;
  • Graduation channel.

These nodes are most often source of basic problems, which can be eliminated after a thorough inspection.

Check the fuel mixture

Before starting the engine of a gasoline braid for grass, check the presence, and the quality of the fuel mixture. Do not save, do not greedy and “do not smarter” in this matter. Repair or replacement of the piston group will cost you too much (sometimes up to 70% of the cost of a new tool). Prepare the oil fuel mixture strictly according to the instructions. Calculate its number from real needs. Excess gasoline left after work loses its qualities over time.

We diagnose a candle and candle canal

If the quality of the fuel mixture is not in doubt, and the lawn mower stalls when starting, then a flooded candle may be the reason. Here, a regular candle key is suitable for repair (every motorist has probably has a spare candle.

  • We twist the candle and wipe;
  • We thoroughly dry it (you should not bake it);
  • Excess fuel in the chamber we drain through the candle hole and dry it;
  • We clean the old candle from the carbon on a sugar or a ladies’ file;
  • We set a gap with a distance of 1 mm (you can check with any coin);
  • We return everything to place and try to start a trimmer for the grass.

Dry the channel at least 30-40 minutes. Otherwise, there is a risk of re.pour a new candle.

If the working candle is working, the nest, where it is located completely dry, and the lawn mower does not want to start, lubricate the threaded connection with gasoline. It should be slightly moisturized. No matter what wonderful spark gives out a candle, there is simply nothing to light up in a dry chamber.

If the trimmer engine for grass still does not start, such a cause as the lack of spark due to weak contact between candles and a high-voltage wire should be excluded. If the connection is of high quality, and there are no sparks, most likely, you have “flew” the ignition unit. Here you can’t do without a master, t. to. The part is not repaired, but sold by a whole knot.

Diagnosis of the filters of the lawn mower

Another reason why the gasoline braid for grass stalls is an air filter. To exclude it, try to remove the filter and start a trimmer for grass without it. If it turns out, then you will have to change the air filter to a new one, or at least blow and carefully clean the old.

You can’t start a gasoline trimmer for grass due to contamination of the fuel filter. This is the next stage of our algorithm. Here we check the state of the filter element and, if necessary, change it with the new. When replacing, try not to leave a suction pipe without a filter, this is prohibited by any operating instructions. Rush can turn into the repair of the piston group of the engine.

Sapun and graduation channel

Often, “delicate” branded models of benzos are not launched and stall due. The main function of this element is to align the pressure in the gas tank. When clogging this node, a vacuum is created in the tank that prevents the supply of fuel. Eliminate the malfunction can be cleaned by cleaning the sounds. You can use a regular needle for cleaning.

The normal operation of the cos with internal combustion engines can be disturbed due to the entry of dirt into the exhaust channel or clogging of the muffler grid. There is such a problem on the models of the older generation. You can solve the issue with traditional cleaning and removal.

How the benzotrimer carburetor works and works

All varieties of carburetors produced by manufacturers of benzotrimmers are almost unrealistic to cover. But, since the design of this module, as well as its principle of operation, is largely similar between different models, you can make a generalized description of the processes occurring in the carburetor. This information will allow the user to understand the principles of the device, eliminate the malfunctions and properly operate.

The basis of the carburetor trimmer for the grass is an integral aluminum case. Below is a diagram of this block.

Below it, there is a diffuser, which is also called Venturi’s nozzle (18). Air is absorbed through this nozzle with a motor.

The smaller this hole, the higher the air flows, and the higher the level of its vacuum in the zone with the smallest diameter.

In the upper part of the diffuser are fuel channels (11,12). Through these channels, the air flow, adds gasoline. The fuel pump itself, nozzles and a system used to adjust the supply of a mixture of fuel with air can be built.in or installed outside.

The throttle flap (9) regulates the amount of air sucked into the carburetor. Its number affects the power that the engine develops. Damper (7) serves for cold launch. It must be closed if you are going to start the unit. After the engine has launched, it needs to be opened, otherwise, the motor will immediately stall.

The pulse channel (1) connects the impulse chamber of the pump to the engine card, namely, with its internal volume. The piston located in the cylinder, producing reciprocating movements, sequentially changes the pressure in the crankcase (vacuum or increase in pressure). Pressure drops make the membrane move (4). Therefore, the operation of the pump is synchronized with the operation of the engine.

The gasoline leaks from the tank occur precisely with the participation of the membrane (4). Gasoline enters the carburetor through the fitting (2). Further, its path lies through the inlet valve (3), the release valve (5), through the mesh filter (6), the fuel channel (10), passes by the needle (14) and fills the camera (16), which has a control membrane (18).

Valve (14) by means of a lever (17) connects to the membrane (18). The cavity that is located below the membrane is connected to atmospheric air through the hole (19).

The device is functioning as follows.

  • During the suction tact, a vacuum is created in the diffuser. This fact causes air leaks. The amount of air entering the carburetor chamber, as well as the engine power and the amount of its revolutions and the amount of its speed, depends on the position of the throttle.
  • At this time, a fuel from the chamber (16) is sucked through the nozzles (11,12), after which it is mixed with leaking air. Gasoline, mixing with air, begins to spray. Thus, a fuel mixture is created.
  • The finished mixture enters the cylinder, where it is compressed by the rising piston and is ignited at the verge of its point from the spark, produced spark plugs produced.
  • Since the volume under the control membrane (18) is connected to atmospheric air through the canal (19), the membrane goes up, opening by means of a lever (17) valve (14). After the valve is opened (14), a new portion of fuel enters the camera (16).
  • After the camera (16) is filled, the membrane (18) returns to its original position, and the valve (14) is closed.

Further, during the operation of the motor, all of the above processes are repeated. To adjust the number of fuel entering the diffuser through the nozzles, a screw is used (13). A screw (15) is also used to set up idle speeds. When twisting the regulators, the fuel mixture is enriched, and when twisting, the mixture impoverishes occurs. Also, in some models of carburetors, you can adjust the idle speed by the amount of the engine by the number. It is usually located on the outside and, when twisting, rests on the lever, fixed on the axis of the throttle.

Thus, using 3 adjusting screws, you can achieve maximum engine performance, as well as set up its uninterrupted operation at any ambient temperature, and even in mountainous areas.
