Re: Rochester carb help possible bad linkage

the quadrajet was designed to run of the primary smaller barrels as a fuel and emissions saving deal. So when I say it runs fine it does. It runs just like a fat heavy dog though like I had a two barrel carb on a giant 454.

When I mash the peddle is when I guess its less of a bog and more like nothing happens. If I go easy on the throttle it then it runs just fine and I can cruise around no problem. BUT There is definitely no secondary's opening.

So runs/idles/revs just fine on the 2 primary's. + I can manually engage the secondary's at idle and it revs fine.

However, I cannot see a way that the throttle setup can move that middle black tab. It just sort of rotates there. I can manually move that black tab and the secondary's move.

How to get the throttle to move the secondary's is the question.

Ill get more pics tonight.

Also there is a port on the front driver side that is not hooked up to anything nor plugged. Any idea what that is for and should it be plugged?

My efi is hooked up to the carb as well and not the manifold.
