ok so progress as of now....
changed jets to 64 (the smallest I have on hand)
no joy
changed power valve (again)
no joy
Plugs show overfueling and idle screws still have no effect... so where is the extra fuel leaking from?
Looking in the carb while engine is running doesn't show anything leaking.
Manifold vacuum is 15.5inches, slowly drifts to 16 than back. Acceleration and decel effect vacuum as it should, so I'd say no air leaks.

I need to find another good carb to use just to make sure I'm even looking in the right direction but my neighbor is a chevy guy (only has Quadrajets).

any other suggestions?
Last day home, ship out @ 4am, so I'll mess with this for a few more hours than get back to it in 4-5weeks.

thanks
Drew
