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
1
deposits to form on the insulator nose
which may result in trouble in operation.
Removing the Spark Plug
Move the Master Control lever to the
N
stop position (0).
Disengage the chain brake.
