Hey Red Dave - Your logic makes sense - I think you've correctly diagnosed the root of Gene's problem! Another way to check would be to take a voltage reading with the ignition on and the motor NOT running. Measure between the coil "+" terminal and a good ground. With the jumper in place the meter should read battery voltage (12.6 or so), and with the jumper removed about 7 volts. This would account for the weak spark since the coil wants a 12 volt input, but is only actually getting 7 volts. Can also try running the tractor with the jumper in place - I'll bet that solves the problem. Solution then would be to install a "6 volt" coil in place of the internally resistor-equipped 12 volt coil.

Timing Your Magneto Ignition Tractor - by Chris Pratt. If you have done major engine work or restored your tractor, chances are you removed the magneto and spark plug wires and eventually reached the point where you had to put it all back together and make it run. On our first cosmetic restoration, not having a manual, we carefully marked the wires, taped the magneto in the position it came off, and were careful not to turn the engine over while we had these components off. We thought we could get by with this since the engine ran perfectly and would not need any internal work. After the cleanup and painting was done, we began reassembly and finally came to t
