Mystery Carb Parts

There are two "tubes" on the carbs that are a bit mysterious to me. I'm hoping someone can help me figure out what to do with them....

A: If you blow air into this tube it comes out somewhere inside the main body of the carb. I have seen pictures of other bikes where this tube is just capped off with something like an automotive vacuum cap. Is that the right idea?

B: Air blown in here also comes out in the carb, actually from the little hole that's visible about an inch to the left of the red oval in this picture. However, I have no idea what to do with this one.
