Grass trimmer adjustment with your own hands
Many masters use chain saws for a long time, and at the same time do not think about the need to adjust the carburetor of the tool. When is it necessary to adjust the carburetor on a chainsaw or brushcutter? If you ask yourself this question, then for sure there are changes in the work of the motor not for the better. In order not to guess, and not to miss the moment of the need to adjust the carburetor, you should adhere to the following recommendations about the need for adjustment activities:
- After the engine has been run-in. Usually the run-in period is 4-5 liters of fuel
- When a different fuel mixture is put in the tank, i.e. the oil type (even its color) and gasoline brand is changed
- In case of changes in the weather, however, this is more important for chain saws, gasoline generators and pumps that are used not only in summer but also in winter
- If the lawnmower has not been used for a long time. The reason for the need for adjustment may be a winter break
- When the fuel consumption increases
- If black carbon deposits are found on the spark plug electrodes
- If there is no petrol in the cylinder or the engine does not start
- If a large amount of exhaust fumes is detected
- Instable engine operation, as well as its hard starting and “sluggish” rpm acceleration
As you can see, there are enough reasons to adjust the brushcutter carburetor. Usually masters, who work with the tool long enough, by ear detect changes in the work of the engine, which bodes well for the need for the adjustment process. Even if you are not sure about the need for adjustment work, their unscheduled performance is certainly not superfluous.
The main problems and malfunctions of the carburetor.
Strainer. There are two problems with this element more often than not:
To find out the reason of the breakage unscrew the fuel filter lid to take out the strainer. If it is just clogged with dirt, flushing or purging will help.
If there are any visible damages on the filter, it is necessary to buy a new one. There may also be damage to the fuel supply pipe (when repairing this element, it is a good practice to check it).
The carburetor starter is in most cases not functioning due to clogs. Acetone or the same gasoline should be used for flushing.
Blowing out clogged carburetor parts with compressed air is an acceptable and convenient repair practice.
Throttle body, carburetor component bundles, and intake or exhaust line are all subject to depressurization. You can check for sure in a primitive way. spread soap foam on the problem area.
Many brushcutter problems are caused by incorrectly mixed fuel. In two-stroke engines, the lubrication is done with a special oil (not conventional motor oil)!) mixed with gasoline. If the oil is not mixed with petrol, the lawnmower will soon break down. Oil / gasoline are mixed in the proportion specified in the instructions of the grass trimmer. It is usually 1:40 or 1:50.
The question often arises: the proportion of 1:50 is how much oil and gasoline?
The device of the carburetor
The lawnmower (lawnmower) consists of an aluminium housing, in which the other parts are concentrated and work as one unit. The carburetor body has a diffuser, a stroke with internal ducts through which air is pumped.
The larger the cross section of the diffuser, the more active oxygen is supplied together with the air. the oxidizer in which the fuel (gasoline and oil mixture) burns.
The ducts branching from the diffuser stroke deliver fuel with which the injected air is mixed, entraining petrol vapors. Outside the main carburetor compartment are placed:
About the parts
Every tool needs a preventive maintenance. Even professional models need at least adjustment, and do it properly, according to the manual.

- Do not save on gasoline. Strictly 92 and higher.
- The fastest way to measure oil is with a medical syringe.
- Do not store the fuel mixture for more than 2 weeks, because the gasoline enters into an oxidation process.
- Always run the mower at maximum power after purchase. Work for 15 minutes, then rest for 15 minutes. Use this method for up to 5 tanks.
- Clean filters (air and fuel filter).
- Avoid wrapping grass around moving parts.
- Do not bump into fences, rocks, trees and other obstacles with the disc. Otherwise, motor and clutch breakdown cannot be avoided.
- As a precaution, once a year, lubricate the hard shaft with lithol-24.
- There is less damage from a line break, but it is a working condition. Continued use is possible by proper pushing on the spool.

The tool’s resource allows you to do the necessary garden work with pleasure. Having chosen any of the described models, you can safely proceed to the running-in of the engine and further proper operation.
How to calculate the rate of consumption of grass trimmer
It is useful for every motorist to know the methods for calculating gasoline consumption rates in his or her own car. This will help properly estimate the cost of money for long trips, as well as the total cost of freight and passenger transportation. There are a huge number of options for calculating the consumption of gasoline in cars. The only question is why it is necessary.
The average motorist can find average and instantaneous consumption
Fuels and lubricants, although for experts, with regard to the confidentiality mentioned above, for accountants of companies that have vehicles on their balance sheet, more specific fuel consumption will be of interest, also the rate of its consumption according to different operational criteria.
Fuels and lubricants and bills
By fuels and lubricants (fuels and lubricants), we mean not only the fuel itself, which is gasoline, diesel fuel or gas, but also various lubricants and water (brakes, cooling). Fuel and lubricants are any materials that are frequently used in the maintenance of vehicles.
The Ministry of Transport of the Russian Federation has developed special standards for fuel and lubricants, and the Tax Code of the Russian Federation does not prohibit the use of standards for its development. In the latter case, they take into account various coefficients, decreasing and increasing, related to the time of year, weather and principles, factors in the operation of vehicles.
Calculation of fuel and lubricants (in which specific fuel will be assumed in our article) in the organization is carried out using the primary accounting document. the account. Invoices contain information about the time of departure and return of the vehicle to the starting point of the route, the rate of consumption of fuel and other consumables, detailed characteristics of the cargo, as well as information about the purpose of the trip and other relevant information. ,
A simple formula for calculating fuel and lubricants
There are some very simple ways to calculate your gas and other fuel consumption. You can use the built-in on-board computer, for example, to calculate instantaneous (instantaneous) consumption, that is, the amount of fuel consumed at a given point in time. It displays a lot of useful information, including average gas consumption per 100 km, fuel consumption for the current trip and instantaneous consumption. Using the on-board computer, you can easily set the parameters for a new trip and see the amount of gasoline or diesel needed on the screen.
But what if your car does not have such a computer?? Use the formula:

Where to rush?
Most modern motorcycles from all manufacturers boast dazzling dynamics and exorbitant top speed. We also see rocket acceleration every time we turn on a commercial with our favorite motorcycle or admire it on a flyer. But why repeat it every time you start from a stoplight? Aggressive riding style on a sportbike can increase fuel consumption by up to 2 times. If you are worried about money it might be a good idea to drive in moderation and postpone the fun to a more prosperous time? In any case keep in mind that you can go much more at medium speed than at maximum.
Over long distances, try to focus on maintaining a constant speed, add gas slowly, and avoid unnecessary braking. Look far ahead, and react in advance to impending causes for speed deceleration, so as not to slow down at the last moment, and in vain change dynamic energy into thermal energy. Also, do not forget that a smooth ride. Is a safe ride.
The lawn mower model described above is designed to work in the homestead. It is great for mowing lawns.
