My DT 50 MXS unfortunately causes problems. It rotates cleanly high up to about 80%, but then the rest is missing. It looks like you are missing fuel on top. It’s all 100% original, also the main nozzle suction nozzle etc. The mixing screw is set exactly according to manual, 1.5 turns out, the needle is in place 2. What I have done so far: I cleaned the carburettor twice, all nozzles are free, every hole. The float is set correctly. The air filter is like new. The connector between the carburetor and the air filter box is right… I removed the cracker and exhaust, was quite oily, I cleaned it coarsely, but I am almost sure that it is not the source of the fault. In my opinion, the spark plug looks ok, brownish, a little rusty on the outside, maybe it runs a little too fat. But it’s always a bit grim, but it’s a little greasy, so I’ve sealed it now. Not at the back, and I definitely drove the DT 50 already fatter and it ran normal… It’s striking that when I start the moped now, it’s short the first two, three times when I turn up gas give, but then no more. It’s like a lack of 10-20 % power. It doesn’t run completely bad, you can drive. But normally the DT 50 MX (is my third) always run around 60, and it runs like that only 50. And at some point it already ran better. Somehow says My gut feeling that the problem is in the carburetor, but I have no idea what else to test… do you have an idea?
