Heres a question that has been picking at my brain. I have a holley single barrel 1946 carburetor on my 3.3l (200cid) engine. I am curious on what these ports for vaccum do? Do they all need a constant source of vaccum? Thanks if you can help me. I can get a "blown up" carb picture of my 1946 if you need it.
