Need a little help

Hello, a well-known has put me a scooter which he probably hoped I got more than cheap. Have me rank today and seen some strange things that I didn’t know yet but no matter my problem. This vehicle has a hose on the carburetor bottom when starting attempts comes out there a liquid has wanted the A.T.U or heard it somewhere? Everything searched and found nothing! Second also a hose that goes down the back right of the tank after front to the engine where the one with hose clamp is folded off and lies free rum and does not find the counterpart. Thanks in advance P.s. that with the battery was so, is one of many that I did not know yet
