Probably a Carter Competition Series AFB 9396S.

According to the info I have the small nipple closest to the linkage is full time vacuum, the small nipple closest to the choke is ported vacuum.

Link to the Edelbrock carb manual, shows the same as the Carter as far as which nipple is what

you're correct. the nipple next to the linkage is full vacuum. ported vacuum is above the throttle blade (passenger side), full vacuum is below the throttle blade, (driver side). no vacuum from either says something is screwed up.
