  1. The most common option is carb adjustment error, which occurs with significant loads on the drive, after prolonged inactivity of the mechanism or when it is used in difficult conditions.
  2. Fuel valve clogging, which eliminate it by relaxation, as a result of which gasoline starts to flow normally through the system.
  3. Loosening and drooping of the cable in the carburetor. May also occur fuel hose extension up to its rupture caused by the action of a significant load.
  4. Clogged breather (check valve), as a result of which fuel does not enter the tank.

If the problem is related to the carburetor assembly, then it can be recognized by the appearance of vibrations of the lawn mowers.. When the hose bursts or the cable is stretched, these components are replaced.

At high speeds

When the braid stalls at high speeds, then this is due to the following problems:

  • clogging or sticking of the valve located on the gas tank cap;
  • the carburetor is out of alignment under the influence of vibrations arising from the operation of the mechanism;
  • problems with the circulation of the fuel mixture;
  • air leaks;
  • The fuel intake hose is cracked or loose.

Carburetor adjust, Based on the operating instructions for the trimmer. To adjust, it is often enough to loosen the tightening of its body. If there are problematic moments with the circulation of the fuel mixture, then it can gradually enter the carburetor. After its development, the engine stalls at high speeds.

If the carburetor is the problem, then the equipment will stop both during a “cold” and a “hot” start.

Right after wound up

The unit may stall immediately after start-up, if the carburetor is misregulated or has been incorrectly configured. this causes uneven fuel supply. The result of this is that the device begins to vibrate distinctly. To troubleshoot, the carburetor is reconfigured according to the instructions for the mechanism.

Also the engine stops when it happens valve clogging, supplying fuel. In such cases, it is simple enough to clean it. If the lawn mower first worked, but then immediately died out, then perhaps the fuel enters the carburetor assembly with some difficulty. The easing of the valve helps to solve the problem, which ensures free circulation of the mixture in the system.

A stop can also be called. air suction in the presence of mechanical damage to the hose (holes, cracks), producing fuel intake. In this case, add revolutions to the drive in order to quickly expel air bubbles from the system.

When heated

lawn mowing often stops when heated. At the same time, it starts, works “jerkily” and gradually stops. This process occurs when gas in the carburetor boils or a shutter in it is installed rotary, and not disk type. In the latter case, the item is changed.
