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.
