POSSIBLE CAUSE

SOLUTION

Engine will not start. (Make sure Ignition Switch is in start position “I”.)

1.No spark.

2.Flooded engine.

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- pletely) and pull starter cord 15 to 20 times. This will clear excess fuel from engine. Clean and reinstall spark plug. Set Ignition Switch to run (I) 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 and repeat normal starting procedure. If engine still fails to start, repeat procedure with a new spark plug.
