Looking at a 7026250

Mudsport96:
So I got to looking at one of the carbs given to me the other day and was wondering what this lever is




since there is no vacuum brake or linkage on this carb,is this spring loaded to have a similar  effect?

carmantx:
That is a 1966 Oldsmobile Quadrajet.  The first year for production.  Many things about that Quadrajet are different and we're soon replaced with upgraded designs.
That arm is the secondary dampener, I believe it is called.  Sort of the pull off for the 66 Quadrajet.  I have one of those on my bench now I am working on.

 From Lars:

 Some very early Q-jets used a small damping piston in the air horn that extended into the main body to dampen the air valve opening, which reduced oscillations when the air valve opened.

Mudsport96:
Cool, thank you guys for the info, probably going to open it up tonight after work and see how it looks inside.

carmantx:
It will look different on inside than most also!
