Carburetor leaking fuel out overflow tube

The number 3 carburetor on my 77 CB 750 is leaking fuel out of the overflow tube. I've never messed with the carburetors before, but I'm thinking that it could be a stuck float. Is there any thing else I should look for that could be causing the problem?

I just had the same problem on my CB350 and it turned out to be a leaking float. The only way to tell is to remove it and shake it to see if there is liquid (gasoline) inside. I replaced it. They can be repaired but not easily. When the solder melts, it ALL melts, as I have been told. This might not be good to try with an open flame!!
