Can you gurus label this carb?

Ok all you carb gurus, lets see who can help me identify all the vaccuum and fuel inlets on my new q-jet carb. The link is to 3 pictures of new carb that have all the ports labeled 1-7. I need to know what goes where and what can get plugged. To let you know, it is going to be installed onto a 304 with no emissions. I think the only things that are hooked up to the current holley are the distributor and pcv valve. The power brakes are running directly from the manifold. Any help would be appreciated.

Re: Can you gurus label this carb?

What about #7, it is right by the choke. Is this a vaccuum actuated choke? hmmmmmmm thanks for your input. Also, I was told that i should lower the float bowl alittle for better off camber running. How do I go about doing it, and how much do I lower it.

Re: Can you gurus label this carb?

I agree with jeepgod. #4 fuel, #5 PCV, #3 vacuum advance, #1 and #2 are bowl vents that usually go to the charcoal canister, but if you are running no emissiions I am not sure what you should do to vent these. You should have some sort of filter or something to keep dirt and stuff from entering the bowl. Somebody out here must know.

Re: Can you gurus label this carb?

It's not the off-camber as much as the bouncing. The float will bounce into the fuel and let another squirt in thru the seat, a few of those and you have fuel running in everywhere.
You want to lower the float level some...If you carefully take the top off the carb, you will see how the tab on the float pushes the needle into the seat, to shut off the flow. I haven't been inside a Qjet in about 10 years, so I'll give you the basics, You want to bend the tab so the needle closes sooner. Usually the float level is measured down from the top of the bowl to the float while gently holding it closed or filling it with fuel. I'd start by lowering the shut-off point about 1/4" , put some wheel brg. grease on the gaskets, put it together, and try it. Tellico will test it for ya.
Take your time, and look around in there so you know how it works.

Re: Can you gurus label this carb?

Looks like a late 70's GM, but there is no choke coil on yours. Let's see if the memory is still good.

1-Smog controls
2-Fuel evap canister
3-Distributor
4-Fuel inlet
5-PCV
6-test port (cap it)
7-TAC contol on the air cleaner

Dritrod already gave you the short and sweet on float adjustment.
