Taking notes is prudent, not a matter of old age ;) Once you get beyond 1-2 things being changed, it is impossible to keep track of it all. Write things down, take note of how things are working and put that in your log too.
Always verify the easy stuff. It takes so little time to throw a timing light on an engine, there's no reason not to make sure things 'stay put' if you play with anything related to the distributor.
The 2bbls do seem to have a reputation for poor idle due to these tubes getting clogged. Goes to show just how important it is to have a decent fuel filter!
You're so close. Keep wrenching away, and you should have this all licked within a day or so.
