Help with my first build please!!!!! And thank you

Feb 8, 2021
So my 2 stroke 80cc motor for my bicycle came with a PZ20 carburetor if I'm not mistaking? I need to know if this is a good carburetor that it came with it should I get something else?? All help is needed on this situation as this is my first build. Also the nipple at the bottom of the carburetor a hose goes on it where does the other end of the hose connect to???
