Without air bleeds in the outboard carbs, the vacuum signal when running only on the center carb can get real strong and pull the outboard carbs open some amount thus opening them before you want them to be open.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
