Sure there is, my 50 cc mopeds had a non vac petcock "on" and "off". No reserve as far as I remember.

The 35 cc Solexes didn't have a petcock at all. The gas just got vacuumed into the carburetor and flowed back when the engine went off. They also didn't have a float with needle nor associated problems.
