What is involved in changing my from a magneto, points, & condenser to and electronic ignition? I have an old antique lawn tractor, 18 horse, that I can't get a spark out of. Long story short, family tractor handed down brother to brother, to many hands worked on it. No one wants it, no spark. So I'm thinking of changing to an electornic ignition? Any advice before I begin? Would it require a new flywheel?
Thanks
John
