Spark Plug
If engine is down on power, difficult to start or runs poorly at idling speed, first check the spark plug.
Fit a new spark plug after approx. 100 operating hours or earlier if the electrodes are badly eroded.
Wrong fuel mix (too much engine oil in the gasoline), a dirty air filter and unfavorable running conditions (mostly at part throttle etc.) affect the condition of the spark plug. These factors cause deposits to form on the insulator nose which may result in trouble in operation.
