Cleaning the throttle can only solve one problem. To ensure the stable and continuous operation of the engine, at least the following aspects should be normal:

1.

The air filter element is not blocked to ensure sufficient oxygen supply;

2.

The fuel pump pressure is normal and the nozzle atomization is good;

3.

The spark plug has no excessive ablation and the flashover is normal and coherent;

4.

The ignition advance angle is adjusted correctly;

5.

The engine is well lubricated without dry grinding;

6.
