1. Check Spark. Remove air filter cover. Remove spark plug
from cylinder. Reattach the spark plug wire and lay spark
plug on top of cylinder with the metal part of plug touching the
cylinder. Pull the starter rope and watch for spark at spark
plug tip. If there is no spark, repeat test with a new spark plug.

lever to run position (pushed in completely) and pull starter
cord 15 to 20 times. This will clear excess fuel from engine.
Clean and reinstall spark plug. Pull starter three times with
choke lever at run. If engine does not start, move choke lever
to choke and repeat normal starting procedure. If engine still
fails to start, repeat procedure with a new spark plug.
