Identifying carb port

This is a Wabron carburetor (bowl removed in photo) off my Honda Hobbit motor. Obviously a replacement. I removed the carb to clean it but when I reinstalled and turned the motor over gas started leaking out of the circled port. I don’t recall anything being connected to it before so I’m not sure if I’m missing something. New bike to me that I’m trying to get started for the first time. Would appreciate any advice.

Looks to be for overflow or ventilation .

Check the float valve for proper function .
