Well, I pulled my fly wheel yesterday and figured out two things. It?s not near the trouble I thought it would be and there is some shigidy going on with my stator. There are two large coils on one side, and one large coil on the other side and then the other copper windings of course. The two large coils have a significant amount of black stuff on them and the all of the pick up points (if that is what they are called) were corroded. Could this be causing intermittent spark on my lower two port side cylinders(4 & 6)? It cleaned up good with some electrical component cleaner and a scouring pad. Should I give it a little die electric grease (to prevent corrosion and rust) then see how it runs or should I just bite the bullet and get a new stator? It still ohm?s out good, and after cleaning it looks good. Also, the fly wheel key has a groove in both sides, is this normal? Should I put a new one in there? And last but not least, can somebody help me out with the torque spec for the fly wheel nut?

If the 2 charge coils are leaking the stator should be changed. The 3rd one is for Quick Start but if it's leaking the stator should be changed too. No need for any kind of grease on the posts for the stator windings. Yes, replace the key. Make sure the bottom of the flywheel nut is clean and flat.

replace the key. you will never know till you try it. removing the flywheel again is not a big deal; looking for torque.

These are the pics I took before and after. I put a bead of silicone on the broken wire insulation but as you can see what ever ozzed out looks like it was getting hot. That tells me maybe the coil windings are beginning to short and melt the laminate.
Thanks for the input everybody, with the help of this forum I am learing all about this motor!
