Clear tube on the carb

[Mjkx8]

Hey guys, as I have said before I am completely new to this and have a question. I have a Grubee Skyhawk GT5...there is a small clear tube that comes out the back of the carb, what is this and what do i do with it?

Which carb? I see they are for sale with an NT carb, a CNS1 carb or a CNS2 carb, depending on the vendor.

Kinda need to see it. The CNS v.1 the tube runs from the bottom of the carb to a barbed tube on the top of the carb. It's the fuel enrichenment circuit that acts as a choke but off the back of the carb.....

it's a cnsv2...it's just a tube that comes out the back of the carb and doesn't seem to go anywhere.....i hope this isn't causing the mountains of problems i am having with it....i'll try to get a picture today

The tube on the bottom of the carb is a overflow tube, if the float sticks open you will see fuel coming out of the tube. Just let it hang, you don't want to close it off.
