My scooter, a Kymco Super 8 4T, was still running perfectly before the holiday. After the ten days of vacation he jumped directly as before. I started, and everything was normal, until it suddenly jerked short, because the scooter briefly took no gas. Finally, he took no gas at all and went out. After I had tried it for a long time, he jumped briefly, but ran only a short time before the same problem occurred. It seemed as if he was trying to jump off again and again. he then didn’t run anymore. When the scooter had stood for a while, I tried again, and he jumped on again, but quickly went out again. I looked at the spark plug that I had re-set. It was black, so I cleaned it, and the scooter ran a bit further, similar to the first ride after the holiday. I then tried it with a new spark plug and the air intake valve on the carburetor turned out a little bit, but the role However, r didn’t jump any more. So it can’t be the spark plug. The old spark plug still worked and the new one also worked. I really don’t know what the problem could be, so I ask if someone has an idea because of my description. I’m surprised that the problem occurred after the somewhat longer service life, since the scooter was running perfectly before.
