SOURCE: my carburetor is leaking lots of fuel.

it's the float valves either worn got muck in them, most common after bike been laid up for a while, old petrol goes 'gummy' rarely it can be a hold float, so it won't float any more, most unlikely with two gone. if carbs still on bike, hit them with a piece of wood with a hammer, a few moderate taps, that way might free the floats and not damage carbs. failing that it's a strip and clean. if grit and muck in float bowls then drain and clean fuel tank or more **** will just get in.

SOURCE: Gas is coming out of the carburetor overflow hose

check for a bad float. a float with a hole in it will 'sink' and thus, not turn the gas supply off when required.

Let me know what you find.

SOURCE: have completely rebuilt carburetor for

It sounds like one of your floats is not functioning properly and may be stuck,have a hole in it,or perhaps the float drop is too large allowing more fuel than needed to come through the system. Regardless you are not going to like this answer.They will have to come off and be checked and cleaned again. I've done a set of carbs as many as three times to get them right so I feel your frustration. Bottem line is they are frustrating,annoying,and fiddly,and they are either right or have to be done again. Compressed air is handy to help you blow out the tiny grot,and so is a set of needles to clean the emulsion tubes (if equipped). Good luck and be patient!
