Hello together…have a small luxury problem and that’s my scooter is a 4stroke benzhou yy50qt-2. And if he runs for a long time in the standgas and tukkers in front of him (ca. from 2min.) then he takes bad gas when giving gas….so he murmurs shortly before he then comes….so kind of stutter! in full gas he is good and otherwise also …. carburetor is only newly installed and is about 1200 km in operation…you can certainly vote a little better …. think I…what do you think he does this …? U And how do you get rid of it … it’s annoying because… If I’m standing at the traffic lights with red and want to leave then he does it … how long is a red phase ??! 30-40sec. Is on anyway annoying. Has ever had such a thing before ! Thanks already in advance. Greetings
