Is there anyway to check a magneto off the tractor? Have been spinning, but cannot get a spark. Not sure if it's possible or not. Thanks.

Have to turn against the impulse so it snaps. Use gloves and mount it in a vise. Ron Mn

I agree with the Green man. If placed upright normal position in a vise with a plug wire out one tower and plug to vise/case/frame and there"s no sort of kill switch disabling it, if you turn the drive CW looking at it, it should at first wind up tight then suddenly SNAP RELEASE at which time that one plug would fire every other time. If she never winds up the spring and snaps/releases shes never gonna fire (impulse assembly or spring problem) although if on the tractor and she was pull started she could still run.

The most typical cause of no fire is the points are burned or pitted or badly gray oxidized in which case cleaning them may make her fire provided the impulse is working

CAUTION !!!!

If mounting in a vise MAKE SURE you only grab it by the bolt flange and DO NOT clamp the case or else you will distort it and the rotor will drag.

Wico mag on a JD turns CCW. I use a vice grips on the lug to make them snap.
