Hey, my speedfight ran without any problems yesterday. When I wanted to go to school this morning, I noticed that the part stutters quite strongly, about half the gas. When I wanted to go home after school today, he went first, had him run about 30 sec so that he already gets a little warm and then started with light gas, but he didn’t want to dress properly anymore and didn’t sound so healthy anymore, he pulled significantly worse than usual when he was still It’s cold. I stopped after a few meters to see if my friends once again allowed themselves a fun (paper in the exhaust or spark plug slightly loosened) But there was nothing there. After that he almost didn’t touch at all, got him to run with gas yet when I gave gas to drive he went out. Now he doesn’t jump at all. What can this be about? LG Sandro
