'49 Cub J4 magneto noise ????

Posted by Deerely B Parted on July 19, 2006 at 13:55:26 from (209.102.128.171):

I had my magneto rebuilt some time ago; when it left here, it wouldn't run the tractor but it was quiet as a church mouse. When it came back it runs the tractor GREAT but there is a "twang" coming from the mag when it runs, reminiscent of the noise a screen door return spring makes only much higher frequency and kind of a pulse to it.
Would suspect the impulse spring but I've had it apart and I cannot see where that is the case. Is there supposed to be a paper gasket between the aluminum casting and the distributor cap? Do you think I'm hurting anything by running it? Would appreciate any thoughts/comments/ideas. Thx, Joe Howard
