Carb leak Hawk250

I am having a fuel leak at the brass pin closet to the top of the carb in the attached picture...


Can anyone tell me what that pin is called and what would cause a fuel leak there?


When I turn on the fuel from the petcock - it streams out like a waterfall.

That pin is just a guide for the inner round throttle plunger - shouldn't be able to get fuel coming from there at all.

its the overflow. you can see the cast tube running up to it. your float is stuck open for some reason.

But his pic he’s pointing to guide pin, over flow is from bottom of carb and the hose attached.
I can’t work out why he claims it’s coming from the guide pin cause no way you could get fuel there up that high

The hose on the bottom is for the bowl drain, not overflow.
