rebuilding carter 2 barrel carb- “small ball”?

I'm halfway through my first carb rebuild and now have the carb apart and soaking. I'm just confused because my rebuild kit came with a "small ball" and it shows it on the diagram, but it's not clear where it goes and I did not see the small ball come out... it may have fallen out, or for all I know it wasn't there in the first place. Can someone clarify exactly where to install the small ball?

Here is a diagram, it's not the exact same as mine but it's close, the small ball is number 26 and is near the venturi assembly on the right side of the diagram.
