Vacuum advance on 318

A lot of people don`t use vacuum advance but I like it for street driving and gas mileage. First thing you would need to do is get your timing set correctly (factory specs if you haven`t changed things on the engine) and then find the port on your carburetor base that does NOT pull vacuum at idle but only as you increase the engine speed. That should be the correct port to attach the vacuum line to. Next, adjust your idle speed and you should have an effective vacuum advance intergrated.
