In either case you would want to check on the points and rotor and cap to make sure the contacts are clean and the point gap is correct. If a distributor you would want to check that battery voltage was getting to the coil. There is a lot more to do if these things don't fix the problem but they are a place to start.

Send me an e-mail and tell me which mag it is and I can then send you the manual for your mag so you can do it the correct way [Reply]  [No Email]

There was 2 common mags used on the A/C tractors. So if you send me an e-mail and I send you the wrong one just let me know and I can send the other one. [Reply]  [No Email]

Blow all sand out of the magnito, and reinstall the bakeite cap,MAKING SURE THAT THE ROTOR STILL POINTS WHERE IT DID PREVIOUSLY. This assumes that you didn't rotate the engine during the above actions. replace the cap with 2 screws, and try for fire. If no fire then your condenser or coil is bad, or the kill switch is grounded out. Good luck [Reply]  [No Email]
