Sounds like the float may be stuck in the carburetor.

As always, Kato and WA gave you excellent advice.

The float bowl valve is surely stuck. I'm moving your thread to the Pure Dirt Forum, where you will get more replies concerning your dirt bike.

Check and see if the brass peice your fuel line connects too is cracked or loose, mine was. Also if the fuel knew doesn't have a clip on it holding it tight it will leak down and you may think its float but its fuel line.
