Hello guys, please help me despair!!! Have a pretty problem and I’m really desperate by now… I bought a Jinlun JL50QT-5 (equal to Rex RS400) and the scooter always goes out several times at the beginning when I start it. If it’s so far that it stays normal but as soon as I give gas it goes out immediately. To the background: The scooter is EZ June 2005 and was driven a total of only 150km after the purchase afterwards he stood up to e in the week only. I then tried to start it and the problem described above occurred. In the meantime I cleaned the carburetor, this was completely green from inside, the spark plug changed and cleaned the air filter and the tank. What else can it be that he goes out as soon as I gas out or how would you proceed to look for the error? Thanks already for your help Mfg Flo
