I've fallen into a routine of having to pull the plugs to the '49 8N, cleaning with carb cleaner (tips are oily and carbon covered) in order to restart. Sunday, I went through the routine, got it started, then looked up what setting the carb should be (it was backfiring). I read to turn main carb adjustment all the way in, and two turns out. Ran fine for 7 gallons of fuel (all day mowing and discing). When she quit, I realized fuel was low, it was a long hard day, and I had done much and it was getting dark, so I shut off fuel petcock, disconnected battery and ran an extension cord to the trickle charger for the night (quit near barn).
Next afternoon, filled her up and pulled a plug. The plugs were gorgeous (no carbon, no fouling, perfectly clean). I tried to start and she fired one two three but wouldn't catch. I pulled plugs and now they were filthy again.
I pulled and cleaned 3 more times and even used starter fluid. Each time I pulled, they were black, oily and filthy again. Gave up for the afternoon. I'm stuck in a catch-22. When clean, it will fire on a couple of cylinders, then only on the first turn when I restart. But it can't put together one whole rotation. It keeps overrunning the starter so you have to wait til starter stops to reengage and try again. BIG PIA! Gaps are at .025" and plugs were installed new a few weeks ago. Suggestions?
