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.
With the on/stop switch in the OFF position, remove
spark plug. Move choke knob to RUN position (pushed in
completely) and pull starter grip 15 to 20 times. This will
clear excess fuel from engine. Clean and reinstall spark
plug. Set on/stop switch to RUN ( l ) position. Push and
fully release primer bulb 7 times. Pull starter three times
with choke knob at RUN. If engine does not start, move
choke knob to HALF CHOKE and repeat normal starting
procedure. If engine still fails to start, repeat procedure
