He didn't mention the CDI or plug or cap " HE SAID THE WIRE"!!! My stock wire broke inside. Couldn't see it, she wouldn't start for days I replaced the "WIRE" and fired right up. Sure glad I checked that before buying a new Mag. Even though you may get a slight spark outside the chamber w/a cracked wire "as someone else mentioned in a prior post " under cylinder pressure it doesn't spark.. Just hate to see you spend it on stuff you don't need... but hey never hurts to have extra parts .do yourself a favor & Replace the WIRE
