Attach the high tension lead to the spark plug. Ground
the spark plug against the cylinder. With the-chain saw
secure from movement, pull the starter quickly while
watching for a spark across the spark plug electrode.
If no spark is evident, retest with a new spark plug or test
plug P/N 5027113-01.
If spark is still absent, disconnect the short circuit wire
from the stop switch. Check for spark again as
previously described. If spark occurs, the stop switch is
defective and should be replaced.
If no spark is evident, carefully inspect the full length of
the short circuit wire and the high tension lead to the
spark plug. Ensure that short circuit wire isn’t pinched or
grounded against any metal surface ( i.e., crankcase,
cylinder). Check the high tension lead connector at the
spark plug for a poor connection and the full length of the
lead for breakage or damaged insulation.
