What does each one of these go to on the Honda carburetor?

It's a 2006 Honda trx 90 cc quad and I'm trying to put a new carb on it because it was missing the carb when I got it. I know you stick the fuel line to one but i don't know if it's the top or bottom also what tube goes on the other one? Very confused please help.

One is probably the fuel line the other an overflow.
Do you have it? I think once you are it you'll know. If not post a pic of the other side.

Buy a shop manual from a Honda dealer and follow the diagrams.

Bikebandit.com has schemematics to look at, suggest you look there.

Turn carb upside down. Blow into each hose nipple. The one with the float and needle will appear blocked--this goes to fuel line.

The other will appear to be open at all times, this is feul return to tank or bowl vent.
