[QUOTE="onthewater102, post: 454612, member: 13702"] Did you clean the grounding connections both at the power pack and wherever the motor grounds to the battery or just around the power pack? If so, did you try swapping the coils & plug wires to see if the intermittent spark issue moved to the top cylinder as Pappy suggested? This would confirm that either that particular coil or plug wire would be the problem before you replace it. I don't know if the coil and plug wire are separate on that motor or if they're one unit, you may have an extra step of diagnostics if they're separate. If the problem remains on the bottom cylinder then you know it's not the coils and is either in the wiring or in the power pack. I'd test the wires' continuity and see if there is any resistance indicating corrosion somewhere in the wire as it's an easy item to rule out. [/QUOTE]
