Default Qjet Connections

I had posted this in another thread but no answers there.

I have a rebuilt Qjet ready to bolt on. It's apparently not from a Pontiac. Have a few connection ports that I'm not sure what they connect to, and I'm wondering if you guys know what the ports are for? The ones circled are the ones in question.

Can I just cap them off?

The big one in the front middle goes to the charcoal canister. If you don’t have one just cap It. The one to the left of that is for the choke pull off. You don’t have the pull off or the linkage that goes to the secondary air flap. You should have them both for cold start-up and to control the rate of opening for the secondary flaps. The other small one to the right is for ported vacuum to the distributor.

Thanks. This one has the electric choke. Do I still need the pull-off and linkage? If so could you post a picture?

Mark,
Your carb doesn't have and doesn't use a front pull-off.

The one on the rear does it all.

Look at the pic of the back of the carb. Choke pull-off is already connected.
