Why does Ou Man est5 10 HP vibrate so much?

1, engine carbon deposit has a great influence on the car. First of all, the engine power is reduced, that is, the power output is uneven and gradually decays, that is, it is getting less and less powerful. Or throttle failure, spark plug, steel wire, ignition coil, crankshaft position sensor and ignition coil circuit will all affect the cause of idling jitter flameout.

2. Idle start means not giving oil when starting automatically, and slowly lifting the clutch directly to achieve the purpose of starting. After the vehicle goes up, fully lift the clutch and then refuel. But it is very bad for the engine.
