Has anyone of you ever re-wound your own stator/magneto coil? or know of somebody who has? If so do you have any advice or instruction to go by? Or where might I find more info on that subject? Also does anybody know of anyone that still does that sort of thing? (or has that art gone the way of all other disposable chinese electronics?) It seems like a simpe thing to do....but I'm not sure if there are any special tricks invovled...or just what may make a coil weaker or stronger.
