I believe I've fixed it.
I had to remove the battery and batt holder and air cleaner housings to see what i was doing. I removed the shift cables and removed the top of the transmission,(after cleaning the area), to get the bellcrank assembly out. The bellcrank has a pin thru it that was loose, so I peened it down solid again. Also, the bellcrank pivot pin was loose in the top of the transmission cover. I removed an aluminum cap to find that the C-clip which held the pin was broken, which I replaced. So it's back together, and tight, and it seems my problems are fixed, so far.
