sounds like you need to take it apart again and se if someting is binding on the float.

Surprised Gray didnt get to this...float is stuck...when fuel enters the carb the float rises and the float valve seals the fuel pathway into the carb from the fuel tank...the float meters fuel coming into the carb. Often you can tap the bottom of the carb with a large screw driver handle or the like and the float will "unjam" if that doesnt work, you need to pull the bowl and make sure the float is free moving.

Did you tighten the drain screw that drains the bowl its a little allen head screw connected to a hose.
