I think we are all saying the same thing, The float is what opens and closes the needle valve! :-D
When it sticks open the gas will run out the over tube. :-D

perhaps the float has a hole or crack in it allowing fuel to seep into the float. causing it to , well, not float. then it would not close the seat and stop the flow of fuel.

What area of the carb is the fuel coming from, under the bowl out the line conection or so on?

 Float is stuck. Which is basically what everyone else has said, I guess. Most likely debris in carb. Sometimes you can tap it lightly and it will stop. Or pull er off and clean it. May be a good time to drain gas, clean carb, air filter and air box. Look everything over in the carb. Make sure jets are clean, slide is clean and snapping back completely closed and no other debris. I'm not saying slide or jets cause overflow, but debris causes issues with these parts also. Good luck!

Very good advice. Clean it with carb cleaner (spray type) then blow the disasembled parts out with compressed air.
