The Puch Maxi MKII works completely fine someday, but sometimes, after 5-10min of use it starts dropping speeds, and when the throttle is applied, it jumps and only partially accelerates,then decelerates and repeats. It may return to normal for a bit of time, and sometimes the engine dies out, but starts back up immediately. We are thinking it could be the engine's sensitivities to the oil mixture, or it overheating. Anyone else had similar issues?
Also missing some small gaskets in the carb, should i replace those, is that a major problem?
Also the moped seems to work better after adding fresh gasoline. (edited)
