If the engine is down on power,

Insert the combination wrench
through the grommet (1) and turn it
as necessary to engage the spark

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.
