Bryce It sounds like your trouble is in the rotor itself or the cap on the mag. You state you have tried some others and are getting the same results. So either your mag is bad or your timing the mag/rotors incorrectly each time your replacing the rotor. Since you have good fire out the coil when it fires, but not out the plug wires, I think your not getting the rotor timed correctly. Forget looking at the books/manuals on timing the rotor. Bring the tractor up to little before TDC on #1 cylinder. Set your mag timing to just be ready to fire. Then set the rotor to be lined up when it does fire. I will bet your Dad knows how to dead time a car/truck motor. Do the same thing to this one. FORGET using the marks and such on the mag. You do not knew if everything up stream is installed right so just dead time it to see if it will run. Then you know that some one has some thing timed wrong up stream.
Truthfully your trouble is why I usually convert these old tractors over to a distributor and coil like more modern tractors. Put the mag on a shelf for a collector item. There are several kits and many used ones available for a IH "M". They will start better and the on going maintenance will be much less.
