Moin, now the ignition spark is finally there and it is running, but it is still not suitable for driving. The scooter has stood for about 5 months, is almost 20 years old and has over 13kkm. After approx. 20 meters (full) gas it simply does not pull anymore and goes into idle. If you then turn on the gas, the engine reacts briefly, but then is immediately idle again. It does not go out. The carburettor has already been cleaned. What could it be about? Greetings
