Technical Carter WCFB part ID

A friend is rebuilding a Carter WCFB that was in pieces, and there are some parts he can't identify from looking at carb diagrams.

Does anyone recognise these as WCFB parts? If they are, where do they go?

Thanks!

 

how big are they?

 

Good question. They are pretty small, air-bleed sort of size.

 

The carb has a 2347S tag, and is supposed to be for a '56 Buick.

Turns out they are air-bleeds. The carb was cleaned in an ultrasonic cleaner and they vibrated loose but pressed back in ok.
