Okay Guys, My sons Moped, Is a Vespa ET2. Not The Best But Its A Ped To Get Him Around. A Few Problems Had Been Going On. The Starter Wouldn't go when you press the elec start button, we found the problem, the wire from the button to the starter had been cut through. So we have fixed it, but there is now a problem. When the engine starts, it will not turn off. Even when you switch the ignition off. You phisically have to take the spark plug off to stop it. Any help on what might be the problem here guys?! Thanks, Brian!
