I have a 1983 Honda NU50 Urban Express. It's got a small 50cc engine with oil injector and one speed belt driven system. The problem is the moped just want to shut off after going for a tenth of a mile. The moped seems like it's not getting gas and dies. But then I kick start it about 10 times and it goes for another tenth of a mile. I was thinking about cleaning the fuel system and the carburetor but I was hoping I could delay in that. Does anyone have any ideas?
