  You should check the points, make sure that the gap is correct. Also it could be a bad condensor.  These earlier A.R.D. magneto's use the Fairbanks Morse magneto head.  Parts are easily available from tractor supply houses.   ;)

   Here's a website i found that looks real good...........http://www.magnetoparts.com/index.html    ;)   Hope this helps ya.   8)

 I my self have no experience with the Fairbanks Morse magnetos. You'll have to do a google search for info or call some repair shops.   Here's another great site for you to contact ........... http://standardmagneto.com/   ::)
