Checking the Spark Plug
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.
If engine is down on power, difficult
to start or runs poorly at idling speed,
first check the spark plug.
:
Remove spark plug - see "Starting /
Stopping the Engine"
:
Clean dirty spark plug.
:
Check electrode gap (A) -
it should be 0.5 mm/0.02" -
readjust if necessary.
:
Use only resistor type spark plugs
of the approved range.
Rectify problems which have caused
fouling of spark plug:
:
Too much oil in fuel mix.
:
Dirty air filter.
:
Unfavorable running conditions,
e.g. operating at part load.
Fit a new spark plug after approx. 100
operating hours or earlier if the
electrodes are badly eroded.
