What kinda Quadrabog?

The 72 C20 I got the other week has a weird configuration on the Quadrajet.
Instead of the usual vacuum piece on the passenger side that connects to the secondaries, mine has a large "L" piece going over the top of one butterfly that is hinged at the back of it and a rod goes down into the secondary opening via a slot cut into the butterfly. Then it connects to the underside of the butterfly.
Anyone seen these before?

Re: What kinda Quadrabog?

any guesses? It doesn't have the numbers stamped on the drivers rear side like the others, I heard that Carter made some for Rochester and put a foil sticker or something into the indented circle under the accelerator pump, but mine either fell off or something..........

Talking Re: What kinda Quadrabog?

The Q-jet shown is a pre 1967 model with an air valve dashpot. There is a piston connected to the linkage which acts as a damper on the secondary air valves.

Later Q-jets have the vacuum dashpots on the passenger side of the carburetor which replaces the function of the piston style dashpot.
