Outdoor Power Equipment (Lawn Mowers, Snow Blowers, Chain Saws and more) Discussions

first off by looking at your picture l would make sure your flywheel is rust free and also clean the coil (u can do this with emery cloth/fine sand paper or an sos pad), before u say the coil is no good. but in my experince coils rarely go bad and by this picture l'm looking at theres a good chance its to rusty!!, l assume u replaced the spark plug?, the only other thing it could be is the ground wire has a short to ground some where (bare wire touching the block).lets say the coil is bad than yes u will need a air gap of 0.10. the spark plug wire is not replacable on its own.
