Troubleshooting strategy

Where to start troubleshooting if the trimmer won’t start? In situations where the tool stalls immediately after starting, it is worth inspecting the following components of the unit:

  • Fuel tank;
  • Spark plug;
  • Fuel and air filter;
  • Exhaust channel;
  • Breather.

It is the breakdown of the above locations that most often leads to the fact that the trimmer does not start well. Let’s look at how to eliminate such troubles.

Air filter

If your lawn mower does not start well or immediately stalls after starting, you should pay attention to the air filter, as it can be clogged, as a result of which air does not enter the combustion chamber, and the fuel does not ignite. To check if the filter has a case, remove it and try starting the engine. If it works, then the reason has been found. The filter needs to be replaced or well rinsed and dried before installation. In the event that you find oil in the air filter, it must be rinsed with gasoline, squeezed well and dried for at least 2 hours before reinstalling.

If the unit still does not start with the air filter removed, it is recommended to check the fuel filter.

How to adjust the carburetor on a lawn mower

Before adjustment, you need to painstakingly clean the filters according to the maintenance in the annotation.

The upcoming do-it-yourself lawn mowers carburetor setting is done with adjusting screws. There are three of them:

Right (L). Fuel Consistency Adjustment for Low RPM.

It is necessary to find the highest idle speed. To do this, slowly unscrew the screw (L) to the right and to the left.

To adjust, turn the screw a quarter of a turn certainly counterclockwise.

Lower (T). responsible for adjusting the engine at idle.

  • Clockwise. increase;
  • Counterclockwise. decrease.

To properly adjust the idle speed, it is typical:

  • Stable operation of a cool motor;
  • Not overestimated revolutions of a hot engine;
  • There is a large supply of turns for the trimmer head;
  • Stable operation of the motor when changing position (sharp lifting or lowering of the knife).

Left (H). consistency adjustment at high speeds. (The screw is adjusted last).

The general adjustment of the highest speed, engine power, temperature and gasoline consumption depends on the left screw (H).

The carburetor setting for lawn mowers with the last screw is done as follows:

  • Open the throttle to full, with all this, give full throttle. Turn the screw clockwise until the revolutions collapse (in this case, orientate by ear).
  • Turn the screw counterclockwise as slowly as possible until the motor runs unevenly.
  • Then turn back just a little, barely hearing measured, even work.
  • For a more pleasant introduction of abilities, it is more convenient to see the work of an experienced user:

It is curious that, based on the beliefs of the creator, the setting (its correctness) is determined by the color of the candle, and not just by the speed and stability of the motor.

Correct adjustment of the carburetor with your own hands in this case. combustion of the fuel consistency without residue, the color of the candle should be light brown.

Insufficient compression

If the compression is insufficient, then in most cases it will not work to start the engine. You can use a car compression gauge to check compression.

  • Unscrew the spark plug from the engine cylinder.
  • Screw the compression gauge in its place.
  • Begin to pull on the starting cord as you would when starting lawn mowers. Do this until the arrow on the measuring device stops moving upward. This value will show the compression force of this engine.

What compression should be? Normally, the compression should be at least 8 kg / cm2. Although even at 8 kg / cm2, some engines do not idle and stall, since the fuel is not pumped up sufficiently. If your lawn mower does not pump above 8 kg / cm2, then you will have to check the cylinder, piston and rings.

Also, poor compression can be due to a loosely screwed carburetor. Check if it staggers. If so, tighten the hardware that holds it securely. Also, if the carburetor is poorly screwed on, you may notice that gasoline drips during operation.
