I'm having the same problem with the float sticking on my Rochester B causing the carburetor to overflow. I tried a different float. I made certain it was adjusted to 1-9/32" and 1-3/4". It is not hitting the sides of the carburetor. I cannot find anything that would be causing it to stick. And the float doesn't have a hole in it either. I've tried two different floats with no success. The problem is intermittent. You never know when its going to happen. Any ideas????
