Why stall gasoline trimmer

A spit with a gasoline drive is a useful thing for owners of private plots, lawns, and when the trimmer suddenly stalls, the work of cleaning the territory from grass stops. The device itself is a fairly complex mechanism, so there are many different reasons for its failure. The most frequent problems are contained in the instruction manual. Know the reasons why the trimmer stalls, should, to independently effectively perform the repair of the device.

What could break

Problems with the benzocosa, due to the fact that this device does not start, are definitely classified by service technicians. They highlight faults with the following mechanism nodes:

• a motor in which the piston and bearings may wear out or fail, crack the crankcase;
• fuel supply system, with possible clogging of the filter or problems with the carburetor;
• mechanical damage to wires, tubes, hoses;
• ignition circuit.

To correctly identify the node where the failure occurred, it is necessary to pay attention to the circumstances under which the trimmer stalls.

When you press the gas

If, when you press the gas, the gas mower stops, then the reasons may be as follows.

1. The most common option is carburetor adjustment failure, which occurs with significant loads on the drive, after a long inactivity of the mechanism or when it is used in harsh conditions.
   
2. Fuel valve clogging, which eliminate its relief, as a result of which the gasoline in the system begins to flow normally.
3. Loosening and drooping of the cable in the carburetor. May also occur fuel hose stretch up to its rupture, caused by the action of a significant load.
4. Airway clogging (check valve), as a result of which no fuel enters the tank.

If the problem is related to the carburetor unit, then it can be recognized by the appearance of vibrations of the mowers. When the hose bursts or the cable is stretched - they replace these components.

At high speeds

When the spit stalls at high speeds, it is associated with the following malfunctions:

• blocking or sticking of the valve located on the gas tank cover;
• carburetor misaligned under the action of vibrations that occur during operation of the mechanism;
• problems with the circulation of the fuel mixture;
• air leaks;
• the fuel intake hose is cracked or loosely connected.

Carburetor adjustrelying on the trimmer instruction manual. To set up it is often enough to loosen the tightness of its body. If there are problem points with the circulation of the fuel mixture, it can gradually flow into the carburetor. After its development, the engine stalls at high speeds.

At idle

At idle, common causes for a trimmer to stop are the following:

• pollution, maladjustment, or improperly adjusted carburetor adjustment;
• air filter clogging;

• a reduction in the speed of the gearbox when it is heated, which is a consequence of the use of an unsuitable fuel mixture;
• throttle clogging;

• air entering the system;
• not enough fuel to operate the gas mowers.

If the carburetor is the problem, the equipment will stop at the “cold” and “hot” start.

Immediately after wound up

The unit may stall immediately after starting, if the carburetor is misaligned or has been improperly adjusted - this causes uneven fuel supply. The result of this is that the device begins to vibrate distinctly. To troubleshoot the carburetor reconfigure, acting on the instructions to the mechanism.

Also the engine stops when occurs valve cloggingsupplying fuel. In such cases, it is enough just to clean it. If the motokosa first started working, but then immediately stalled, then it is possible the fuel enters the carburetor unit with some difficulty. A weakening of the valve helps to solve the problem, which ensures the free circulation of the mixture in the system.

Stop can also be caused air leaks in the presence of mechanical damage to the hose (holes, cracks), producing fuel intake. In this case, add speed to the drive in order to more quickly expel air bubbles from the system.

When heated

Motokosa often stops when heated. At the same time, it starts, works "jerky" and gradually stops. This process occurs when gasoline in the carburetor boils or the flap in it is installed rotor, but not disk type. In the latter case, the item is changed.

It is found that the trimmer heats up if damaged ignition wire or coil. In order for the device to start working normally, parts are replaced.

When opening the air damper

It happens that the unit stalls when you open the air damper, normally working at idle. This is due to the air leakage system caused by the presence of fuel hose cracks or problems with seals. Also, the carburettor dosing system may malfunction, while the mococon will stop after the flap opens.

All the possible reasons for the gas mower stalling and how to eliminate them are contained in the following video.

There are many reasons for stopping the mowers, but the most common problems are related to its carburetor. They can occur in any cases. The most problematic option is when a serious breakdown occurs, and you will need to purchase new parts or change the benzocos.

In order for the trimmer to work normally for a long time, the requirements of the operating instructions should be strictly followed. It is necessary to fill the unit with a suitable fuel mixture for its composition, the device should operate at a moderate load.
