Welcome to SV
The carburetor on now is a new Edelbrock 1411, 750 cfm. From what I can tell there are two vacuum ports on the carb. One is for
timed vacuum=vac. adv. for emissions controlled engines and the other is for distributors vac. adv. port for non=emissions controlled engines. Mine def. does not have emissions items on it.
Thanks so far. I will take all the hints I can get.
