Hello together, I bought a scooter mentioned above cheaply. At the beginning I did the usual maintenance (oil, candle, carburetor cleaned, air filter new, all gasoline and air pipes new) After that everything was still fine, was super satisfied with the scooter. But then at once he makes mute. To shop, still everything is fine. Come out of the shop, want to go home, and suddenly he starts to jerk during the ride. As if something limited w It’s about 30 times, 40 times and then these symptoms come. When it comes to gas, it can also be that it makes them mute. Well, with about 30 to go home and immediately into the garage. Carburettor cleaned again, and candle checked. But it was everything i.o. (deer brown candle) Now I’ve already searched some forums, but all write you should check candle carburettor air filters. That’s exactly what I did and it seems all right. Is there anyone here familiar with the matter is u Is there anything to it? What about this CDI? Can they have a broken or shaky contact? Questions about questions…. I’m grateful for any help and every tip. Greeting Sven
