I just got home for the evening and, as stated, wont be home to even look at it again till Mon. But it's bugging the crap out of me every minute.
I mentioned the tractor was backfiring, but it was actually afterfiring. It was spitting gas out the carb and backfiring in the exhaust. I know the difference, it's just so much more natural to type backfire for some reason.
As for the static timing, I checked several times, I checked everything after changing anything. After the initial cleaning the points and slight adjustment, the timing never changed throughout the process.
One way or another, it has to be a compression issue. The fuel is now as it should be, the spark is now as it should be, the only missing major component of an old engine is compression.
Without breaking into it yet, I'm agreeing with the valve issue, whether out of adjustment, or not closing. The occasional puffs of white smoke and sometimes sounding like it might have fired, makes me think it's burning uncompressed fuel.
After having to adjust the carb, replace a less than great spark plug wire, and the issue in general, it's not going to surprise me if at this point I open up the engine and find out it wasn't in the condition he claimed it to be or he wasn't as good as he claimed to be, and I'm going to find a foreign object like a nut or snap ring jammed in the exhaust valve preventing it from closing.
That type of situation would explain the sudden change. I had something similar happen in a fresh rebuilt chainsaw once. Chunk of the old spark arrester sucked back in through the exhaust port and killed it. Tried and tried and tried to start it with no luck, opened it up all too late to find the piece had dislodged from the exhaust valve and destroyed the cylinder wall through multiple starting attempts. That's why I'm kind of leery (other than I just know better) of turning the engine over any more than I had to for diagnosing the problem.
You all got a few days to get your bets with Jonathan on the table... Lol
And I will get pictures up when I see my tractor in daylight again.
