Vance,
Sounds like you have done fairly exhaustive work on
the carbs...however I wouldn't rule out ignition
problems.
What shape is your distributor in? When I bought my
car I had .035 of float in the dist shaft! Kinda makes
setting the points at .014 irrelevant. I had similar
problems at idle and starting -- at higher rpm the
engine seemed to somehow fool me and "carry" itself. I
would backfire on initial acceleration as my lack of a
good spark was dumping raw fuel down the exhaust.
Other than that, I would disconnect and plug EVERY
vacuum line, esp the anti-run-on crap (my guess if not
ignition related), and re-start the diagnosis process
from there.
Wouldn't worry too much about the bypass valves -- if
you want to eliminate that variable during
troubleshooting, I would just pull them off and duct
tape off the holes.
