I have a 1988 Bayou 220 I'm trying to repair for a friend. I cant get it to spark. I've purchased a shop manual. I've also replaced the ignitor, coil and pick-up. It still wont spark. When I turn it over with the starter it sparks one time when I let off of the start button?? I've read the stator and it reads good with an ohlm meter. Any help out there??????
