Helping a friend to get his Ford 2000 tractor running. I tuned it up. I put all new parts, plugs, wires, points, condenser, cap, rotor, coil. Checked timing & mechanical advance, rebuilt the carb, and cleaned air filter. After a month he complained of hard starting especially when warm. I noticed the coil had oil in the tower where the coil wire is inserted( the old one was also leaking oil and the wire had swelled from the oil). After putting on a new coil it starts like new. Is the coil overheating somehow? The coil I replaced said on it"s side "for internal resistor" also "made in China". Is there a resistor or should there be a resistor in the High tension circuit? Thanks for the thoughts,original 6 volt system/generator.
