you can google how to ohm test your coils. its not difficult and know for sure if its your problem, Ive done it. You can remove the winding from you laments and buy new windings and install them on your laments yourself. I had to do that with some Wico coils on an old Firestone I restored.I used some evinrude ones I had. But I ohm tested them first to find out they were bad.
