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 grip and watch for
spark at spark plug tip. If there is no spark, repeat test
with a new spark plug.
Remove spark plug. Move choke knob to RUN position
