so i started up my bike today and the overflow of gas is pouring out of my airfilter, when i took it apart and checked for obstructions there was none the float was floating just not shutting off the gas when it filled the bowl it simply flowed out of the little hole above the bowl i assume thats the overflow hole or is it a defect what would cause this problem plz help
 
What carburetor do you have? 2 stroke or 4 stroke engine?

There could be trash in the needle valve that the float operates. The float might be good but if the valve is blocked open by dirt then it will allow fuel to flow.
Pull the fuel line off at the carb and blow through the carb fuel inlet nipple or spray some carburetor cleaner through it.
Let us know what you find.

It's not unheard of to have a float that needs adjusting. Not a common problem but it has happened.
If you find no dirt in the needle valve try this:
Reconnect the fuel line to the carb with the float bowl off. Open your petcock and gently push upward on the small movable metal part(pivot or tang) that the float rests against. You should be able to stop the fuel flow. If so then bend that tang down just a tiny bit. There are actually two small 'fingers' that the float pushes up on. You'll have to bend them equally. This is typically a trial and error way to get the float to function right.
Get back to us with what you find.
