Thanks for all the comments and advice. I was putting it back together and the fiber(?( bushing that separates the armature shaft from the rear cap deteriorated and mostly disappeared. I am guessing this bushing dies two things, takes up some slack on the armature and possible does some insulation with the current, not sure about that hallucination though. I plan to hit the hardware store for a replacement unless I can find a reasonable new one. I refuse to buy a $75 rebuild kit for a 3 cent bushing, even if it is to be found in the kit.
Any thoughts?
