Gas dripping from a tube at the bottom of my carburetor?

Question

I have a Honda 50 dirt bike which is 4 years old and has been used very little. I took it out today for the first time in a year. It ran fine, but quite a bit of gasoline dripped from a short black tube which comes out of the bottom of the carburetor. What is the tube for and why would it be dripping so much?

Answer 1

the first answer is probably the most likely but don't forget to check the float bowl drain s***w. It may be seeping.

Answer 2

needle & seat is leaking or the floats need resetting..

its an overflow tube for when the carbies have to much fuel in them..
