Can anyone help? Please excuse me for not know the part names but I am pretty new to this moped stuff. I just bought a moped recently and it runs well but is leaking gas from the plastic tube on the bottom of the bike. It looks like it might be at where it connects to the carburetor (I think that is what it is). Is there some type of sealant that can be used on this? I live in Cincy. If you can help please email me back.
