Jiangling Shunda gas door is always broken. What happened?

Jiangling Shunda gas valve is always broken for the following reasons:

1. There may be too much carbon in the throttle, combustion chamber and spark plug, which leads to unsmooth acceleration.

2. The engine oil used is not good, and the engine oil can't burn well during acceleration, which leads to the acceleration of oil cut-off.

3. The aging of the ignition coil or insufficient voltage leads to poor ignition.
