Update to all- organbuilder, you were right ten years ago, when I first fired up the engine, mouse nest stuff blew out all over the garage. The mice had departed before the several hundred mile journey from Vermont. I had since put on a new exhaust system. Right off a couple days ago I found that I had failed to set the idle mixture screw- after three carb rebuilds over the years, I confused a thought of the instruction with doing it- instead of screwing it in until it stops then backing out a turn, I had left it Five turns out- a little rich. That supports Bob's theory- a rich and high idle pumping unburned stuff into the muffler. The dwell was 45 degrees- I reset to 32, and the timing which was right for that 45 dwell was off for 32. I reset the timing but left the ball a little below the needle mark as the engine would almost die when I went to the mark. I did not disconnect the vacuum advance to time the engine, as the manual did not mention that, but maybe they assumed everyone would know that you should? I put on a new muffler. I have not yet gotten a new coil, and I took it out for a test drive (had started and run like a champ for all the testing) and the engine promptly stalled under power going downhill and would not re start. The carb seemed wet with gas, so I left the truck parked on the road for now. This is the same symptom I had once before the muffler blew up- stalling and not restarting. My plan is a new coil and to more carefully rebuild the carb again. edit: will also try a vacuum test and some carb adjusting before a carb rebuild. What do folks think?
