A hole at that location is a Chevy deal with a vacuum tube in it for the air cleaner hot air valves.
No Pontiac Q-jet used this hole/tube.
Pontiac Q-jets has a guide for the pull-off bracket instead of the tube.
What is the stamped application number on your carb?
What is the cast number in the little ring back on the float bowl?
If you have a "Frankencarb" you may have a massive vacuum leak there.

Not all makes/years Q-jets used the spring on the spring on cam follower lever.
1968 and later Pontiac does.
