Suzuki 2 Strokes

Can a T20 rotor go bad? I really can't see anything that could go wrong but don't know. Pulled off the stator after checking and re-checking everything on the planet numerous times and still have weak spark on the right side. (Not hot enough to burn the gas). I noticed that the rotor is scraping on 2-3 areas of the stator. Not sure if that's normal but don't think so. Pulled the rotor off and seems to be on correctly and the key where it should be in the rotor groove.
It will idle with just one side and while running, I have about 8.5v on the left (good side) and about 7.5v on the bad??
Changed out points, condensors, coils, checked all connections many times. Switched the wires at the coils to see if I could get it to change sides. Won't even start at all then.
Every once it awhile it will fire correctly for a couple seconds but not long at all.
Thanks, Doug
It's driving be nuts!

GOT IT!! Different stator! Blowin' smoke out both sides!

New problem. Ran fine for a mile, then started losing power til it died. Pushed it about half mile home, then tried it again and popped right off and ran fine again. Gonna leave it home til I get this figured out. Won't run when hot....HMMMM?? Anyone?

condenser then coil?

ran out of fuel in the float bowls? Blocked breather in teh filler cap.

Thanks guys. Been working on those things to no avail. Now the thing is back to firing on just one side. I'm done for today......
