How to properly set the ignition on a gas troops
The main problem is the lack of a spark. Most likely, the reason is in the candle. Either a dozen was formed on it, or it is faulty. Twist it and carefully inspect the electrodes. In the presence of a soot formed with gasoline pouring, in addition to cleaning the candle, it is necessary to check the fuel supply system, perhaps there are leaks there. In the absence of a spark, you need to clean the candle from the car. A good way out can be its heating over the switched gas burner, scraping from its surface of frozen flows of the fuel mixture.
After cleansing the candle, test its serviceability. To do this, put on the part on the top of the cap and bring it closer, holding it in one hand, to the body of the motor block at a distance of about 1 mm. With your free hand, try to start the engine.
Otherwise, check the gap between the electrodes. Try to put a razor blade there, and if the electrodes are tightly clamped, the distance is optimal. If a free blade is felt, it is necessary to adjust the position of the electrodes. To do this, lightly tap the screwdriver on the back of the central element. When the electrodes take the optimal position, try to start the motor again. If the spark does not appear, test the serviceability of the magneto.
Other problems with the ignition system are possible:
- Weakness or absence of a spark;
- A feeling of an unpleasant smell of burned plastic in the part of the mechanism where the ignition coil is located;
- Cracking when starting a motor.
To do this, unscrewing the mounting bolts, remove the upper part of the ignition system casing. Then turn off the power wire, put the coil element and pull it out. Carefully inspect the appearance of the part. The presence of black spots indicates that the current did not enter the candle, but melted the winding of the coil. This situation is especially relevant for motoblocks with contactless ignition.
The reason for this malfunction is in poor.Quality contacts at high voltage cable. It is required to clean or completely replace the wires. In devices with an electronic ignition system, an automatic fuse is provided that turns off the power in case of malfunction. If your car has any other ignition system, the cable will have to be disconnected with your own hand. If the spark is knocked out when you turn on, check the tip of the candle, most likely it is contaminated.

How to set a spout ignition
With minimal experience, but good theoretical knowledge can independently set the ignition. For this, you only need to clearly observe the instructions below.
The most important part of the setting is to find the correct position in which the timing star will be. In order to find it, they use special marks that are applied at the factory when assembling the engine. The desired mark is similar to the letter “t”
Husqvarna 435 Chainsaw
In this position, the piston is at the dead point. This is an extreme position after which the piston will return back. It is necessary to rotate the rotor until the ledge on the crankcase and the letter “T” coincide. You can do this with hands or stagnation kik. Electrostarter does not need to be used
The desired mark is similar to the letter “t”. In this position, the piston is at the dead point. This is an extreme position after which the piston will return back. It is necessary to rotate the rotor until the ledge on the crankcase and the letter “T” coincide. You can do this with hands or stagnation kik. Electrostarter does not need to be used.
For configuration, it is necessary to combine the “T” mark and the protrusion on the engine crankcase
On different scooters, marks may look different
If the piston only minimally moved down, scroll yet until the tags match. Catching the right position is not always possible the first time. After they coincided, you need to study other marks: they are on the timing star. Usually these are three points or holes that are on the outside of the star. They form a triangular figure if you connect them visually
Pay attention to the fact that one point is more than others. After the ignition adjustment, it should be on top, and the other two tags remain opposite each other. They should stand horizontally
If the ignition is contactless, it is regulated as follows. In order for the engine to work smoothly and correctly, you need to adjust the ignition of the mixture at the right time. For this, after all the marks are installed in the right places, you need to figure out how the contactless principle works in general.
A feature of BZS is the presence of special sensors, switch, two types of winding of the ignition coil. When the sensor is closed, using a rotor equipped with a magnet, an impulse forms, which enters the switch, it pumps the current coming from the generator and directs it into the primary winding of the coil. After that, the charge falls into the secondary winding, where a high voltage forms, with which a spark used to detonate a gasoline mixture appears. Ignition adjustment. This is the combination of labels on the crankcase and star. Usually you have to remove the valve cover.
- Tags are set described above in the way.
- In order to set the ignition angle, you can unclench the stator fastening and configure in accordance with the technical requirements of your vehicle.
- Make sure that the marks or holes are in the correct position.
How to set ignition on a walk.Behind tractor
Consider how to adjust the ignition of a walk.Behind tractor. The ignition system of the walk.Behind tractor is quite simple
Before the ignition installation, it is important to make sure that this design forms a spark, which in turn will cause ignition of the fuel fluid located in the internal combustion chamber
In order not to contact specialists in trifles and save your funds, you need to understand how the ignition and settings of the ignition coil are adjusted. Consider how to set the ignition to the Unoa tractor MB 1 and MB 2.
You can set the ignition using a spark. It is necessary to turn the crankshaft so that the tags of the pulley and the gas mechanism coincide. The runner distributing gas flows should show on the high.Voltage cylinder wire.
You need to unscrew the nut a little, changing the position of the mechanical structure, which determines the moments of the high.Voltage pulse.
Then you need to get a high.Voltage wire from the system cover. He is in her center. Then place contacts at a distance of 5 mm from a motor.Cultivator.
After that, the ignition should be enabled.
Next, you need to turn the mechanical structure, which determines the moment of ignition, clockwise to the mark 200
The aforementioned design carefully turn the other way
There is a spark between the central high.Voltage wire and the mass of the motor cultivator. After that, you need to quickly tighten the tag nut to avoid ignition.
You can set the ignition by sound. If the owner has a good ear, then this method of checking and adjusting the ignition is quite suitable. In other words, this is a contactless check of candles.
The contactless method involves the following procedure:
- First you need to start the engine.
- Then you need to slightly loosen the trimbler.
- Corps reserve slowly turn on 2 sides.
- The mechanical structure, which determines the moment of the formation of the spark, must be strengthened in the state of the greatest power and the largest number of revolutions.
- Then listen carefully. When turning the interruption system, clicks should be heard.
- After all the actions done, you need to tighten the tenter nut.
The method with a stroboscope works as follows:
- First you need to warm up the engine.
- After that, attach the strobe to the walk.Behind tractor.
- The sensor responding to the sound must be attached to the high.Voltage cylinder wire.
- Dismantle a vacuum hose and drown it out.
- The strobe will emit light, which should be directed to the pulley.
- Start the unit engine again, leave it to work idle.
- Turn the trambler.
- Fix as soon as the pulley label indicates the mark indicated on the lid of the walk.Behind tractor.
- Twist the torn nut.
It is described above how to check the ignition coil. When installing the system, it is advisable to use the instructions, especially the owners who are faced with this for the first time.
Adjust the coil. The task is not from complex.
A trimmer does not start for the grass for cold reasons
To begin with, we will analyze the situation when it is impossible to start the engine of the lawn mower to the cold. What does this mean? Surely Kosari came across a situation where a trimmer for grass starts on hot just perfectly, but you just have to make a short break, as the problem arises. This problem with the start of the engine after it cools. What could be the reason? Of course, no one excluded all the above factors, but if the situation is constantly found, then there is no need to check them. If a hot lawn mower starts well, and problems arise on the cold, then you should look for the reasons inside the CPH (cylinder-piston group).
To identify a malfunction, you will need to use a compressometer. We screw the compressometer into the hole instead of a candle, and after that we drive the starter handle. Measure the pressure inside the cylinder. Compression. The amount of compression should be at the level of about 8-12 atmospheres. After the tool has warmed up (it is enough to work for 15-20 minutes), you should repeat the verification procedure. If the compression on the hot engine is below 8 atmospheres, then the CPH fault is appropriate. This means that the rings, the piston and the walls of the cylinder are worn out.
You can fix the situation by replacing CPG
When replacing it, it is important to take into account such a recommendation as abundant smearing of parts with motor oil inside the cylinder. This is necessary so that in the first minutes of starting a new cylinder with the piston, no formation of
With a decrease in engine compression, fuel consumption increases, and the productivity of the tool falls. You can work with such a tool, however, with each subsequent hour of work, wear increases. One day, the lawn mower will not be completely launched even with warming up.
It is interesting! You can warm up the engine of the lawn mower with low compression by pulling the starter handle. When warming up, the metal is expanded, thereby the compression increases.
Why do I need to adjust the ignition
In some cases, when the engine does not work, ignition control will require. Of course, first you need to check the performance of a candle and a high.Voltage cable using a plug.
The ignition control on a two.Stroke engine is necessary to ensure timely ignition of fuel in the engine combustion chamber. Below is a scheme from which you can understand the principle of operation of the internal combustion engine.
The spark in the spark plug should appear when compressing the piston, when it reaches a slightly. Когда поршень проходит ВМТ, топливная смесь воспламеняется, в результате чего поршень падает под воздействием энергии взрыва.
Therefore, if for any reason (mainly due to the shift of the flywheel to the shaft relative to its starting position), the fuel is heated before the piston passes the vehicle, then it returns back and the crankshaft rotates in the opposite direction. This movement can damage the starter node, cut off the starter cord, etc. D. In this case, this occurs early ignition of fuel.
It can also be later on the ignition on the trimmer: after compressing the irreparable fuel, the piston lowers and the spark appears. In this case, the engine will either not start or significantly lose power and will not gain momentum.
Ignition on the trimmer. The principle of operation and possible malfunctions
If the owner of the lawn mower wants to establish the operation of the ignition system on his own, he should understand the principle of operation of this unit. In the internal combustion engine, it consists of a flywheel and magneto (coils). In turn, the flywheel includes a impeller that performs the function of cooling the motor and a number of permanent magnets.
The first way
You can check the work capacity of the magneto using a tester. To do this, you need to perform such a sequence of actions.
- Correct the tester correctly: use the resistance measurement function and set 200 Ohms to remove the measurements of the primary winding.
- The first electrode of the measuring device is sent to the “mass” of magneto, and the second to the output contact. If the primary winding is working, the indicators should be from 0.4 to 2 Ohms.
- Install the tester switch by 20 kOhm to diagnose the secondary winding. Then send the first probe to the cap of candles, and the second. To the “mass”. If everything is in order, the indicators will vary from 4 to 6 kOhm, depending on the model of the trimmer for the grass, whether it is Patriot 547, Husquarna 128 R or a technique of another brand. If the chain is cut off, the infinity value appears on the tester screen. And if there is a short circuit, zero will be displayed on the display.
Adjustment of a trimmer carburetor for grass with your own hands video
Independent adjustment of the carburetor of the lawn mower with your own hands is impossible without preliminary work, cognition of theory, awareness of the device of the fuel system. Annotation for carburetor repair.
Husqvarna rancher 455 problem
You can adjust the carburetor of the lawn mower with your own hands
Lawn mowers, like the entire bench tool for the garden, is not difficult to maintain equipment. Adjustment of the carburetor of the stihl benzotrimmer. Setting up the carburetor of the lawn mower craft. Repair, configure without the help of others you can and necessary. For example, adjusting the carburetor of the lawn mower with your own hands. It is 5 minutes.
The carburetor from the lawn mower is a node in the power supply system. In it, like all carburetors, there is a process of mixing air and fuel (gasoline) for the upcoming supply to the motor cylinders.
In this process, the main thing is the correct proportion of fuel and air, why the carburetor is regulated.
The main problems and malfunctions of the carburetor
Mesh filter. There are only two tasks with this element more often:
In order to find out the cause of the breakdown, the fuel filter lid is unscrewed to extract the mesh filter. If the mud just accumulated on it, then flushing in gasoline or purge will help.
With visible damage on the mesh filter, it is necessary to put a new. Carburetor tuning of a favorite benzotrimmer. There may also be damage to the fuel supply pipe (during the repair they practice checking this element).
The starting device of the carburetor almost always does not work due to blockages. Should be used for flushing acetone or the same gasoline.
Purging parts of a carburetor with click of compressed air. Permissible and comfortable repair practice.
The hull of throttles, places of ligaments of the parts of the carburetor, intake or graduation pipeline. All of the listed parts are subject to depressurization. You can probably check the simple method. Spread the problem area with soap foam.
The base of the carburetor of the lawn mower. The duralumin case. It contains a diffuser (a hole with internal contours). Air is pumped through this hole. Cleaning the carburetor of the MTD lawn mower. The speed of oxygen (air) is dependent on the cross.Sectional (passage opening) of the diffuser.
Diffuser is equipped with fuel channels. Adjustment of the Patriot Benzotriot Benzotrimmer carburetor. Fuel is drawn from them using a stream of air.
The principle of operation of the carburetor of the lawn mower
The throttle dashes determines the amount of air for supply, and the power of the motor directly depends on this.
A combustible pump (its membrane) is sucked into the carburetor system. Then passes through the fitting in the carburetor. Then the liquid moves through the intake and exhaust valve of the pump. Adjustment of the GUTBROD lawn mower. Filtered with a net. On the needle valve moves into the membrane chamber.
- Air supply to the tube with an air septum (damper). The partition regulates the intensity of the air flow.
- The fuel supply system is certainly narrowed by the mixer to accelerate the flow.
- Gasoline through the float chamber and nozzle with narrowing. Cleaning the Gardenlux lawn carburetor video video. The chamber with a float regulates the temporary volume of gasoline. In the float chamber, the pressure level is neutral, and in the tube with narrowing is already small. Thanks to the pressure drop, fuel seeps through a jickler.
- Acceleration of the air flow contributes to the transfer of fuel (gasoline) and its spray. Ultimately, a fuel mixture of the desired proportion or density appears.
- The air-fuel mixture seeps into the cylinder of the motor through the fuel tube.
The level of air density in the system depends on the area of the open air damper. The more extensive the damper is open, the greater the fuel consumption and power.
Simply put, adjusting the carburetor on a benzocos. Creating a good fuel consistency due to the correct air supply.
How to set a ignition on a trimmer
Often, owners of gasoline cos are faced with the fact that ignition does not work on their technique. In most cases, the problem is really in this node. To fix it, you need to adjust the ignition on the trimmer. But at the same time, there are frequent cases that the ignition coil is working and a breakdown should be sought elsewhere. The ignition system is arranged equally on four.Stroke and two.Stroke internal combustion engines, therefore, the correction of the malfunctions of this node is carried out in a similar way. In addition, the technique of different brands has an almost identical design of this most important component of the tool, which means that the process of adjustment will be identical for both the trimmers “Soyuz” or “Prostr”, and for Huter or samples of other brands.
Among the wide Spectra, gasoline bite of the trimmer for grass is characterized by high energy parameters and characteristics. This was achieved primarily due to the use of a two.Stroke or four.Stroke engine high power.
If we take into account the disadvantages of gasoline binders of “two.Stroke”, then there are not many of them and they are laid down in the intricacies of maintenance: fuel preparation, filter replacement planned technical measures for maintenance.
Models with a four.Stroke engine. The most modern and powerful equipment for mowing the lawn. Thanks to a powerful motor, prolonged continuous work is ensured, despite the fact that the noise level is less than the analogue of a two.Stroke.
Ignition adjustment algorithm
The ignition on the trimmer is adjusted quite simply.
Remove the casing from the engine by unscrewing all the bolts holding it. For example, on the Patriot gasoline (Patriot) PT 2540, to remove the casing, you need to unscrew the air filter housing, and remove it with a flat screwdriver from the latches. After that, the plastic case will easily remove.
