Where is this resistor in the wire schematic?Yes I am loosing the term loosely. Simple facts is the exhaust smells like raw fuel. For the 4 hours it ran with the new coil it was not like that. This tractor has seen mods through the years. The old guy I bought it from reconditions tractors and sells them. The resistor definitely may not be factory, and it is acting weird. When I ohm it out it just jumps from 1.5 ohm to infinity. My meter does not like it. The resistor that is on it looks like a coil of wire with brown lacquer coating. When I did the ignition tune up not 100 hours ago I did not replace the resistor. I replaced points, plugs / wires, and coil. I am pretty sure it all came in a kit and I just connected the new coil to this resistor. I took the resistor out of line just to test and the new coil is hitting hard again, but it is not running right. That being said I think the damage is done.
Is the resistor color coded to understand it's value?
Additionally, the cap and rotor on the tractor, are the contacts brass or aluminum? If aluminum contacts, those tend to corrode or fuzz up in as little as several hours with lots of aluminum oxide. When this happens, things get hot. Additionally, the aluminum oxide will destroy the points by causing arcing.
