Hello together, to get me for the summer a small Spasmobil I bought myself in the summer a Mbk Booster Rocket as a hobby scooter. The hook was that the scooter did not sprung with the old exhaust, so I ordered a new one and the scooter ran make the first kicks again like a 1. Now my consideration was to combine a 70s sport cylinder in combination with a 17.5 carburetor to have a little more suit. At the exhaust I have myself for a TNT silent pro e I drive the 17.5 carburetor with the original air filter (have changed the pillow for that of malossi). So now comes the hook . I have had by now almost every main nozzle that there is, but I have always the same problem . The scooter starts at first occurs, accelerates perfectly high and after about 200 meters it chokes off as if the float chamber was empty. So to exclude that the carburetor dirt from the tank I pulled the tank and the Benz i filter cleaned, the hoses look good so far, but I just can’t get rid of the problem. After a few hours I am now so far that I think about building everything original again and let it go because that’s how it went. I have another 2-stroke moped, where I also changed the carburettor and it runs without any problems. Is there a mistake on my part that I’m looking over? Vllt can help me. Thanks
