I got ahold of one of these about a year ago and would use it to putter about the lake. Well after de-winterizing the thing, i cant get any spark. I've done some wire investigation but i cannot for the life of me find where the spark is being lost. Its an intermittant drop in spark. very rarely, it will muster enough spark to ignite a couple of rotations and then die again. When i can get it to spark, its usually an extremely weak spark. I'm hoping to find a wiring diagram for it because i have one yellow wire coming off of the ignition control module that seems to lead nowhere. I'd be very grateful to any help, advice, or experience that can be offered forth.
