If you can screw the idle jets all the way in without stalling the car, then
you have an internal gas leak in the carb. Seeing that a vacuum leak allows
more air into the intake system, leaning the carb by running the screws in,
should make it quit idling sooner, instead of later. Either way, a car
shouldn't idle with the screws all the way in, which makes me think that
something has gone wrong in the carbureator.
