I have a 1949 8N that was rebuilt a little over a year ago. It was converted to 12V at the time of the rebuild. It has a side mount distributor.
It has developed a new problem, the engine sputters and back fires (maybe once, not a lot) after it runs for about 15 seconds. I was able to limp it back to the garage but barely. I have changed the points, condenser, plugs, plug wires, distributor cap, rotor and I blew air through the fuel line to see if plugged - no issue there.
I have a spare carburetor so I swapped that, same condition. I'm ready to roll the tractor down the driveway and make sure it's lined up with the swamp in front of my house!
I checked spark on all the plugs, getting spark. The points were set a .025" with the gauge that came with the points. The coil is NOT getting hot (at least not that I can feel). I'm stumped on this one and don't know what else to check.
