Question about Motorcycles
I can not get the carberator to stop leaking fuel from the bottom of the bowl, hence it won't start. It tries to but won't. I thought the float was stuck but seems fine. as soon as i turn the gas on it free flows out the bottom. WHY
Fuel is controled by float height and the float needle , is the needle good and clean where it seats and is float height correct ??

Sounds like a stuck float. try gently tapping on side of carb near bottom where float assembly is located to see if it frees up if it doesn't you will need to remove and clean your carb and check your float adj.

I had the same deal. After the rebuild kit, it still happened. Against the advice of my mechanic, I filed the top of the float ever so slightly, decreasing the chance for the top of the float to come into contact with the dome of the carb. 2 years later, no leaks. And always - always - turn off the fuel when not mobile ;>)

This sounds to me like a carb float being stuck open. Turn off the gas and drain the offending carb. Next, turn the gas back on and sharply tap the float bowl with the plastic handle of a screwdriver as the fuel bowl refills. The goal here is to vibrate the float to free it up. If doing this process a couple of times does not free the float I would remove the carb and clean it with a spray carb cleaner. Clean the air filter then re-mount carb. Next Remove the water trap bowl at the bottom of the petcock, (gas valve). Dump it, clean it and re-mount it, ( not all bikes have a water trap bowl ). Install an inline fuel filter.
Please rate this solution. Thanks!

The adjuster tang on the float (in green) rises and falls to maintain fuel level. It pushes on the float needle to stop the flow and drops to let fuel in. Did you loose the needle? If all parts are there, gently bend the tang upward to lower the gas level in the carb.
