How the lawn mower carburetor works
The throttle valve determines the amount of airflow, which has a direct effect on the power of the engine.
The correctness of the carburetor option is determined by the operation of the motor and by the color of the candle. Adjusted
Independent adjustment of the carburetor on the Chinese trimmer, quickly and easily set the carburetor to
The fuel is sucked into the carburettor system by a pump (its diaphragm). Then flows through the nozzle in the carburettor. The liquid flows through the inlet and outlet valves of the pump. Is filtered by a strainer. Goes to the diaphragm chamber through the needle valve.
- Air delivery to the tube with an air baffle (flap). The baffle plate controls the intensity of the air stream.
- The fuel system is necessarily narrowed by a mixer to speed up the flow.
- Gasoline flows through the float chamber and restrictor nozzle. The float chamber regulates the temporary volume of gasoline. In the float chamber, pressure level is neutral, but in the tube with constriction, pressure level is already small. Thanks to the pressure drop, the fuel flows through the nozzle.
- Acceleration of the air flow promotes the transfer of the fuel (gasoline) and its atomization. Eventually, an air-fuel mixture of the right proportion or density appears.
- Air-fuel mixture is leaking into the engine cylinder through the fuel tube.
The area of the open air damper depends on the level of air density in the system. The more open the valve, the greater the fuel consumption and power.
Simply put, the adjustment of the carburetor on the gasoline mower is to create a good fuel consistency through the correct air supply.
How to adjust the carburetor on the chain saw
The upcoming adjustment of the lawnmower carburetor with their own hands is made by adjusting screws. There are three in total:
Right (L). adjustment of fuel consistency for low revolutions.
Need to find the greatest idling speed. To do this, slowly turn the screw (L) to the right and to the left.
To adjust the idle stroke, turn the screw a quarter of a turn, always counterclockwise.
Lower (T). is responsible for adjusting the motor at idling speed.
To adjust the idle speed specifically is characteristic:
- steady operation of the cold engine;
- not too high revolutions of the hot engine;
- there is a large RPM margin for the trimmer head;
- stable operation of the engine when changing positions (sudden raising or lowering of the blade).
Left (H). adjusting mixture at high rpm. (The screw should be adjusted last).
Left screw (H) affects overall adjustment of maximum rpm, engine power, temperature and gasoline consumption.
Adjusting the lawn mower carburetor with the last screw is done as follows:
- Open throttle to full throttle. Turn screw clockwise until rpm drops (in this case, guided by hearing).
- Turn the screw as slowly as possible counterclockwise until the engine runs rough.
- Then turn back just a little bit, barely hearing a steady, even operation.
- For a more obvious application of skills, it’s more convenient to review the work of an experienced user:
It is interesting that from the point of view of the author of the video, adjustment (its correctness) is determined by the color of the spark plug, and not only by revolutions and engine stability.
Adjustment of fuel supply. Low RPM (L).
First adjust the upper right L screw, i.e. the fuel rate at low rpm. For STIHL fs series trimmers, the L screw is turned all the way clockwise, then back one full turn counterclockwise. This adjustment is also valid for many other trimmers. If you go from the particular to the general, you should achieve a stable idle speed when turning the L screw, that is, the lawnmower should run smoothly and without unnecessary vibrations, once you have done this, go to the LA (T) screw. It should also be noted that turning the screw counterclockwise adds fuel to the mixture, turning it clockwise reduces the amount of fuel in the mixture;
The second stage of the adjustment, is the adjustment of the idle speed with the LA (T) screw, here the setting is made only by ear. Turning the screw clockwise increases the working RPM and turning it anti-clockwise reduces the working RPM. It is important to make sure that the mower head is not spinning at idle speed. It should also be noted that the L and LA screws are adjusted in pairs, i.e. changing the adjustments on one screw may require changing the adjustments on the second screw. After you have achieved a smooth engine with minimum vibration. go to the adjustment of H.
Adjusting the fuel flow. High RPM (H).
Third step, adjustment of fuel rate at high rpm. H. For STIHL trimmers, turn the screw fully anticlockwise and then a quarter turn clockwise. adjustment of trimmers of other manufacturers is generally practically the same. normally turn the screw all the way counterclockwise, then start the mower and throttle all the way down. Then turn the screw clockwise (usually 1/4, 2/4 turn) to reduce the maximum RPM by about 5-10%. The lawnmower adjustment is now complete. When adjusting the carburettor with this screw, turning it clockwise reduces the fuel supply, turning it counterclockwise increases it.
It must be remembered that correct grass trimmer adjustment not only increases the service life, but also saves fuel. It is important to check that the grass trimmer is working correctly. the lawnmower should run smoothly without any noticeable vibrations and pick up speed evenly. Do not rotate the trimmer’s head when idling.
Check the condition of the fuel and air filters and the spark plug before any adjustment of the trimmer. Perhaps the problem lies in these elements. The fuel filter must be easy to blow and must not be visibly dirty. The spark plug should be clean, dry and have a slightly brownish tint. If the spark plug is wet and has a black tint, it means it is flooded, you need to reduce the fuel supply by adjusting screws. A whitish tint on the spark plug indicates that the mixture is lean, it is necessary to add fuel supply.
If all the elements are okay, and the adjustment does not give the desired results, it may be time to clean the carburetor. How to clean the carburetor of a chainsaw, we will tell you in one of our next articles.
