I have a Massey that has kicked my butt. Bought the tractor fixed it up everything is brand new, coil, wires, plugs, condenser, rotor cap, distributor cap, and new points. The tractor will run great for 10 minutes once it get hot, then it will short out. The coil will be extremely hot. Let it cool it will crank back up, but run super crappy. Tried a resistor on it, the tractor will not even crank when hooked up. Can someone please give me a solution???
