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.
