Do a compression check on each cylinder. It sounds like an intake valve is hanging open or simply needs adjustment. An intake valve hanging open (even JUST ONE) will drop vacuum dramatically. Also it will cause alot of 'crusting' of the carb when it is running thus the possible dirty 'center tube' of the carb. But usualy an intake valve that is hanging open, even just a little bit, will cause the engine to run so poorly that the car will barely pull itself in low gear on flat land.
