I get a small spark i can see when holding plug against engine.. it wont start the bike or even make sounds of wanting to start... what causes a small tiny spark that wont ignite gas i squeeze into plug hole??? is this a points problem or a bad plug problem? plug was black as charcoal when i took it out.. was a new plug... or could this be condenser i just put in?? i checked all connections.. no bad grounds.. re soldered it 3 times with same issue... what could it be??
