Hello together, have the problem that my Benzhou YIYING YY50QT-02 Jack Fox in the stand is pushing properly forward and wants to go off. I already tried at the stand gas. I turned down the stand gas as far as it was possible. Nevertheless, he continues to push forward and the wheel turns cheerfully.. (Because of the low stand gas he vibrates/tucks really strongly in the stand!) I have already done the following things: Carburettor checked and cleaned Varioweights from 4gr on 6gr Does anyone have an idea?? I’m really perplexed.. Greetings Kutti
