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

pull starter cord 15 to 20 times. This will clear excess
fuel from engine. Clean and reinstall sparking plug.

release primer bulb 7 times. Pull starter three times with
