Why During Operation The Tiller May Stall Under Load?

When your hitherto trouble-free tiller begins to act up, it’s very annoying. It is doubly annoying when this happens in a situation where it is full of work and without a tiller, like without hands. It seems to be running normally, but it is worth giving it a load, and it immediately sneezes and stalls. What is the reason for this “betrayal”?

The main problems of the engine tiller.

Offhand to answer this seemingly simple question will not work. There are a lot of reasons why it is “naughty” and the tiller stalls during work.

Conventionally, they can be divided into several groups:

  • problems with fuel supply;
  • engine start failures;
  • control and automation faults;
  • problems with silencer, cooling, etc.

If you have noticed problems in tiller work, the main thing that you need to understand is that there are problems that can be easily fixed with your own hands, even if you are not particularly good at technology, but there are situations when it is impossible to do without a competent specialist and proper equipment. The most important task of you, as a host, is to quickly and correctly determine why your tiller stalls and make the right decision.

Problems with fuel supply.

If during operation the tiller has stalled and no longer starts, then most likely the problem is in the engine or the launch system. The first thing to do in this situation is to scrutinize the spark plugs. Dry plugs mean that the fuel has no access to the engine cylinders.

In such a situation, first of all, check the presence of gasoline in the tank. It is possible that, according to your forgetfulness, tiller has consumed all the gasoline, and you need to refuel it for further work. If gasoline is fine, check the fuel valve. it may be closed. In this situation, too, there is nothing difficult. open the tap, and the engine will come to life again. It is also often the case that during operation the tiller stalls with a strong roll. You need to put it horizontally. If the engine starts up in this position, it means that there is little gasoline in the gas tank and when tilted it simply does not come from the gas tank, you need to refuel.
The next thing that often happens is that the drainage hole in the fuel tank cap is clogged. It is necessary to clean it, and the problem will be solved. It often happens that some rubbish got into the fuel system, especially considering the current quality of gasoline. In this case, you need to remove the fuel valve, drain the gasoline from the tank and rinse everything thoroughly, and then disconnect the connecting hose from the carburetor and thoroughly blow it.

Startup system malfunctions.

If when checking the candles were wet, but the motor does not start, then it will be much more difficult to detect the fault:

  • may fail the ignition system;
  • due to the depressurization of connections, air leakage may appear;
  • there may be an unclosed air damper in the carburetor;
  • carburetor breakage.

Failure of the ignition system is an unpleasant moment, but you should not panic and immediately call a specialist. First, turn out and inspect the spark plug. If you find carbon on it, clean it with emery, wash with gasoline and let it dry completely. Very often, after such a procedure, the motor starts to work normally.
If the motor still does not start, and you feel qualified enough, check the gap between the electrodes. The required value is specified in the manufacturer’s instructions, but due to the constant vibration during operation, it may change, and the tiller may stall on the move. Adjust the gap to the desired value by bending the side electrode.
With the rest of the problems of the ignition system on the move will not work out. If the insulators of candles or electrical wiring have burnt out, then they need to be replaced. You can also close the “STOP” button to ground, and until the circuit is cleared, the engine will not start. Also, the reason that the engine does not start may be a breakdown of the contacts in the squares of the spark plugs or a gap in the gap between the magnetic shoe and the starter. Finally, the starter itself may be damaged and will have to be changed.

Another common reason for which the motor tiller under load “chokes” stalls. air leaks. If this is due to the depressurization of the carburetor connections, then you must first tighten the plugs and tighten the fastening bolts, and then check and replace the gaskets if necessary. The engine will “choke” with the carburetor’s air damper open. To fix the problem, it must be adjusted, making sure that it goes freely without distortions and jams.

If the tiller is not gaining normal power, you should check its muffler. The products of combustion of fuel over time clog the silencer, forming a thick layer of carbon on its walls, so it must be cleaned periodically. To do this, you need to remove the muffler, plug the exhaust port with a clean cloth, rinse it first in gasoline, and then wash it off with a detergent, and finally dry it with a hairdryer.
Sometimes the tiller stalls when working and from elemental overheating. If you push the throttle with the throttle fully open and the motor, instead of accelerating, lose momentum, then this is a clear sign of overheating. The tiller needs to be stopped and allowed to cool completely and then run again.
It is not the whole list of reasons why your recently completely serviceable tiller may stall, even under a small load. Virtually all tiller nodes undergo significant loads during operation, so minor faults and breakdowns are not uncommon. Therefore, finding that something is wrong with the tiller: background noise, twitching, strong vibration, etc. Immediately shut off the engine. And only after the motor has cooled, you can start troubleshooting. But this is a topic for another conversation.
