I have a Carter, not a Holley?

Yup, that's the correct port for the vacuum advance.

Okay, so it was hooked up right. That place where the "wood screw" someone put in there, I am going to remove. My kit will be here tomorrow, if I am not brave enough, I may drop it off at the garage on Monday, and let them rebuild it. I watched a youtube clip, didn't look hard, but I dunno!
I did spray around the throttle shaft when it was running, seems okay there. Shaft is still tight.
