the gasoline), a dirty air filter and
Erratic idling behavior, poor
acceleration
unfavorable running conditions (mostly
at part throttle etc.) affect the condition of
the spark plug. These factors cause

which may result in trouble in operation.

counterclockwise until the engine
runs and accelerates smoothly.
