Ive got a 98 Jetski 750stx with no spark. it started running with really low power and then died and now has no spark. Ive replaced the stator and the ignition box with 'good used ones', but idk how true that is, and i bought new plugs. Ive ohmed out almost everything (kill switch, whole ignition box, plug wires, stator..) and I cant figure it out. The only hint is when I crank it, then let off, i see a nice blue arc for a split second...thats it. Any help would be greatly appreciated.
