4barrel carb
Expert:  Matt J replied 5 years ago.

The diagram is for a 4 barrel carb. GM just uses a simple carb for there pictures. If you look at the diagram on the carb the letters on the card are the most important info. If you look at the carb you have it will have the same letters.

thanks
Expert:  Matt J replied 5 years ago.
Sorry for the delay I am trying to find a diagram to show you. It hooks to a port that has vacuum when the engine is running if that helps at all while I see if I can find a picture of the exact location.
