I have a problem that I can’t handle myself. The following problem has been around for a long time, so I tried to solve the problem myself and suspected the error on the carburetor. But unfortunately without success. I turned a lap again today and at the beginning the box ran great, without any problems stuttering. But the warmer the engine got the worse the stuttering. So where the engine was completely cold, nothing was until it got warmer. The candle picture is 1A. So If the engine is warm: From a certain position of the slider (approx. 1/4 gas) the engine stutters. Whether in stationary gas or during acceleration. When accelerating, the stuttering is extreme. If I open the gas tap immediately (except for full gas), it is not stuttering. The stuttering is also when I drive to the Bsp 140 km/h, take the gas completely away and then turn it again to 1/4 gas. So it is not possible to lie on the carburettor, because I checked and cleaned everything there. I didn’t change or screw around. For me, this sounds like a carburetor problem, but I took the carburetor completely apart, looked at each nozzle and checked the suction sockets for leaking. Can it be on the pick up or on the ignition coil? I don’t know what else to do. I can’t remember what it could be anymore. So many components don’t come up anymore. I’ll buy another spark plug tomorrow, but don’t think it’s because of it. Have new spark plugs + other control unit installed. Can jemnad help me or have an idea what it might be about?
