My Ciao ran OK yesterday, but today I started it and it ran for a few minutes then died. When I went to start it I noticed that the guys in the restaurant next to where I parked my moped had hosed off the sidewalk and got a little water on my moped. As soon as it started running I noticed a little smoke coming from inside the engine area. (I'm not sure exactly where.) Also, I noticed some oily, gassy stuff dripping from under my exhaust. The crankcase has always been caked in oil and it ran fine before, but I'm wondering if that might have something to do with it. Although it ran OK for a few minutes when I first started it up, now it dies after a few seconds. Could there be a gas leak or something? The carb is tight, and there are no holes in the fuel line. Where else could it be leaking from?
