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.
2. With the Ignition Switch off, remove spark plug.
Move choke lever to run position (pushed in com-

position. Push and fully release primer bulb 7 times.
Pull starter three times with choke lever at run. If
engine does not start, move choke lever to choke
