I see the area your talking about, Its been a while since I've studied one of them... what keeps dirt water etc. from entering that area if its open to the bowl ?
Seems like I remember its only an opening when the accelerator pump is active??
I'll have to dig one out and investigate more.
Back when these carburetors were used in production most of the air cleaners were only mesh or oil bath which won't cause a restriction due to their design. Pot of oil with air moving by... so these designs weren't causing issues.
Same reason the Model B Zenith could use the oil bath in 1932 without moving the float bowl vent.
