It does breath air in both directions, but not fuel . the steel balls are checkvalves that let air pas but not fuel.
But having 2 balls in one hole makes it just a open hole that squirts gas. I should have posted pics. I have no clue why they had 2 steel balls in there, one was about 1/2inch and the other was just bigger then a BB. I took the small one out.

Idk it just bugged me that i had a constant stream of gas running down my new frame/engine.Damn old timey cobble stone streets shake the **** out of everything. Now if i can just get the carb to stop pissing.
