Hello, I have a problem with my scooter (Yiying yy50qt). He was standing in the shed for about 2 months. Unfortunately, he doesn’t jump any more. I was told that I had to clean the carburettor nozzles. I removed the seat and now look directly at the carburettor. What do I have to dismantle now to get to the nozzles. Does not want to bring it across the city to the dealer to have it repaired. Maybe one of you also had such a scooter and also the problem before. D anke in advance.
