Rieju Rs2 no power, don’t go

Hello, have me here now, because I don’t know any more. I bought a Rieju Rs2 50 a few days ago. The previous owner wanted to finish you up and drive himself but lost the pleasure of it, because he noticed that you are probably too small for him, and he did not want to continue to grope. Besides some problems with the electrics (only concerning the light), someone seems to have confused cable there. Is there a problem: starting by e-starter works with Choke gan Z well and after a short while she runs in the stand even without choke. In idle turn up also works quite well so far, could maybe turn up a little faster but since I have no experience with the AM6 engine this could be quite normal. So it does not take disturbingly long until you turn up in the stand. However, if I insert a gear and let the clutch come you start to go with the speed in the basement (rolled however at 1-2 kmh) and then wants to go out. I have a I tried to demonize the carburetor, but this one is so tight on the air filter that I didn’t get it down. The spark plug is dark brown (very dark) and slightly damp, which I would push on it, but you didn’t get a load but only ran warm in the stand and I gave a few gassings. This is what I see. no more standard but I can not say that for sure, because the one who had you before could not tell me about it: The exhaust seems to be Malossi, at least Malossi is on the rear silencer. The cylinder has a different color than the head, however, nothing stands on it (both, however, the cylinder is significantly lighter) and the air filter outlet to the carburetor seems to have been glued with hot glue. Otherwise, everything can be done If anyone has any idea what it might be that you want to go out on the run, I’d be grateful for suggestions.
