I was wondering if it's doable with a rebuild kit (if theres such a thing) or would I be better off buying a new unit. I pulled teh cap and wiggled teh rotor, it has quite abit of play from side to side. Also there was a loose steel ball laying in there . BTW it still runs but it could do better. I have a parts motor but teh dizzy has about as much play in it as well. Need opinions,advise.Thanks,Mike in TN.
