Hello! I bought a brand new Dirt bike /pocket cross. I drove with it for about 3 hours and now I have the following problem: As soon as I start it I can drive around the 30 sec, after that there is automatically gas and then dies off. I can always steal this with the start and it always happens the same. To rule out some mistakes I have to say again that everything is new only 3 hours. What should I do now? mfg. Flo
