my friend has a mobylette. and it starts fine when it is cold. it runs great and has monster exceleration. but after it is warmed up adn u turn it off by pulling the engine stop lever and keep it off for 5 mins or more it is a REAL bitch to start. like it takes a couple runs down my half mile hill to get it started. what we do is pedal untill the engine starts turning then pull the engine stop lever and hold while pedaling and let go. it starts like this when it is cold. its not spark or fuel cause the carb is clean as a whistle and it backfires sometimes when you pedal and hold the engine stop thing in. it is also not getting TOO warm cause i can hold my hand on the cylendar for 10 secs before i have to let go. also i cant look at the spark plug cause the engine sits too upright to get my plug wrench on it.anyone had this happen or know the cause.. any answers would be greatly apreciated. also this model has a ignition off button when you turn it it also turns the engine off. which should you use and why are there 2 engine stop things?
