AFB Bearings

[Dizzydean]

I was cleaning out my AFB 400 and a small bearing came out of unknown. I checked the check valve and its still in there. Any ideas where this goes. The universal carter kit has one but it looks a bit bigger. No diagrams with the kit. Thanks for your help.

Possibly the accelerator pump check ball?

Large one goes in accelerator pump well and small one goes between booster and body assembly.
