Go look at your PDF, it shows the nipple on the linkage side (#51) as FULL TIME VACUUM, not ported. Number 50 in your PDF is listed as Ported Vacuum, exactly as I said.

A simple visual also confirms the vacuum sourcing for either nipple, below the throttle shaft is full time (#51) and above the throttle shaft (#50) is ported.


That's an ERROR. I had one, The OP CONFIRMED there's no vacuum at idle on either port. it's a universal carb, EGR does NOT use full time vacuum. And yes I know that, carb 101. Look at the pic of the actual carb, both on the same level.


Calm down gent's!
Look, my carb look very much like the one in the pic. It has the text Carter AFB - Competition Series though.
It has the electric choke and the vapor return nipple (hose is not there anymore)
It has the two nipples 51 and 50 - but none of them gives a vacuum signal at idle. The drivers side nipple sits lower than the pass side nipple and that why I started this thread, I was confused smile
