Army,
I am newish to mopeds, finally owning one after borrowing off and on over the years. So now I need to do my own repairs...
I just picked up a very custom Garelli SS 1978 with lots of cool alterations. But after riding it around for an hour, it started to peeter out. I noticed that the fuel lines seem empty coming out of the top tank all the way to the carb. There is an in-line filter right after the top tank but the fuel isn't even making it to it - there seems to be no fuel running out of the tank/petcock. My thought is that maybe there is junk in the intake from the tank (I have no idea how it works in there) or that the petcock is messed up. It is the 3-toggle petcock that has a closed/open/reserve setting (though I'm not sure which is 'reserve') I was dumb and unscrewed the black knob from the petcock to see what's in there only to have a spring and metal disk pop out and gas running out all over me. I put that all back together (I hope) correctly. It seems to have a slight leak either from the petcock or from the line attached to the petcock after messing with it.
Do I need to replace the petcock? How do I check if there is a problem inside the tank? The fuel is a bit old but looks clean (about a half tank in there.) Or is it another problem like the carb isn't sucking in fuel or air filter junked up? What would be your first moves to trouble shoot. Before the lack of fuel in the line, this Garelli was running along perfectly. Thanks!
