87 Force 35. What could it be? It seems to idle low ok. When I put it on high, I get misfires and the rpms fluctuate. I also sometimes see sparks flying from the stator to the engine block on the side where the ignition wiring is.

Sounds like you have some wires that may have the insulation worn off from touching the flywheel?? You shouldn't see sparks.
