Hi guys,I have an old 8N tractor that had been running fine. It started spitting and sputtering, backfiring etc. I've had issues with the points before so that's where I started, new points. That didn't help. So far I've done the following, lol.
Replaced front mount distributor with new one, new cap, new coil, new points, condenser, rotor cap, ballast resistor. New plugs, new plug wires, checked and double checked for correct plug wire placement, it's all correct. Same problem, cranks, idles ok for a bit then starts spitting and sputtering. Replaced gas tank because the old one was rusted and needed replacing anyway, new fuel filter, new carburetor. Checked all wiring, checked compression, it's all fine and it's still doing the same thing.
This was originally a 6 volt system as were they all and I was seeing 12 plus volts at coil, I thought it was supposed to be somewhere around 8V so that's when I changed the ballast resistor thinking maybe it was bad, didn't help.
I'm at a loss, the only thing that hasn't been changed is the governor but I thought the governor was basically to keep it from over-revving.
HELP!
