CL77 Float Bowl brass screw

[sibes67]

Carbs are 26's, Keihin's, each bowl has this brass screw angled out the bottom right. Threads have a tiny hole going thru them, and there is a small washer too. What is the function of this screw? I see it on the parts diagram of these carbs, but there is no part number associated with it. Just wondering. Thanks again.

Sounds like a drain screw.
