Re: Elto Cub coil/magneto substitute question

[mikesea]

I have been looking into coil specs trying to find a listing of coil inside square, plus outside specs. Once we can find the sizes and what will fit then the next step is check the coil pri and sec windings. I think I have seen the Phelon pri and sec wiring specs somewhere? I do know the improvements over a square laminate, to a round laminate is a gain of about 20% with no other changes. That’s why you see round cores being used on motor cycle engines and anything that is pretty new.
So If we find a square coil make sure that it fits the laminate if lose make shims of magnetic steel to get it snug for best coil performance. That is all I know about it I am sure you guy’s know more about it than me the newbie.
