I have a 100% stock 1981 tomos silver bullet. It always starts right up and runs great. Last week I was cruising along at around 25 mph when the engine died. I could not get it restarted (good thing it has pedals).
Back home, I checked - got plenty of gas, good gas flow and good spark. It will (after several kicks) start and run on choke. When i give it a little throttle it dies. On these the choke is on the throttle. My guess is the pilot jet is clogged and i need to clean the carb and jet. Does that sound right?
