OK SO HERES THE PROBLEM... I HAVE THIS 1977 CB550F SUPERSPORT AND EVERYTHING IS CLEAN. THE CARBS LOOK AMAZING INSIDE AND OUT BUT IT IS GIVING ME ISSUES... MY CARBS LEAK GAS OUT OF CARB 2 AIR FILTER?? I DONT UNDERSTAND WHAT COULD BE GOING ON MY CARBS ARE SYNCED TO PERFECTION, I RIDE AND ITS FINE UNTIL I GET TO A STOP OR RED LIGHT THEN IT DUMPS A MESS OF FUEL OUT OF THE INTAKE? THE FLOATS ARE SET AT MANUAL SPEC LEVEL.. NEW GASKETS NEW O-RINGS... WHEN I JIGGLE THE CARBS SOMETIMES IT WILL GO OUT OF SYNC AND DUMP FUEL... ANY HELP? I WILL POST PICS SOON WHEN IT IS PICTURE WORTHY

You need to check the overflow for that carb undo the bleed screw does fuel come out? I had the same prob on my 650 the overflow tube was blocked so it just over flowed out the intake.
The float valve must be leaking or floats sticking for it to overflow like that.

I had a bike that was dumping puddles of fuel and it was a stuck float valve. It was actually just a small piece of debris (duh-briz, you know) Anyway, that was on an 85 nighthawk, I pulled the carbs, pulled the floats out and the valve was blocked by some sand or something, sprayed it out, put it back together and there it was, perfect runner again.
