Yep, the same part was used on the older 50's and 60's Rochester two and four barrel carburetors for the same purpose.

If you look at this exploded view of a 2G Rochester it's part number 62 part of the accelerator pump check ball mechanism.

I fail to see it in any exploded view of a Quadrajet. The equivalent check ball parts are 32 and 33 of the diagram below

What year or part number is the carburetor?

It doesn't go anywhere in a Q-Jet. It's a 2-barrel Rochester 2GC accelerator pump ball spring retaining clip. Throw it away.
