I have recently bought a 2001 Avanti Autopower Moped. My son removed the fuel tank and doesn't remember which lines from the carburetor go where. There are 2 inlets on top of the carburetor. I am assuming one goes to the fuel tank and the other to the inlet I see on top of the crankcase as a vacuum line? Anyone with experience or photos that could help me out I would greatly appreciate it! Thank you, Bill
