Hello, I have a scooter Suzuki AP 50 Bj. 95 with approx. 20,000km of mileage. The scooter is completely original and has never been throttled. I brought the scooter back to life after about 8 years of service life. I cleaned both tanks for this purpose. I cleaned the carburettor already 2 times (gassers put into petrol overnight, and everything blown out with compressed air). Of course I changed all liquids and used a new battery. I have even checked and cleaned the clutch and installed a new drive belt.The spark plug is deer brown.So, now to my problem: When I start with full throttle the scooter has no power and accelerates very slowly. When accelerating with slow-rotating gas it is partly OK. In the cold state it seems to be better than in the warm. When I arrive at approx. 50 km/h it accelerates relatively quickly to the final speed of approx. 68 km/h. He drives up a mountain without significant loss of strength with approx. 60 km/h. It feels as if the carburetor would swallow itself while accelerating. Strangely, the ONLY when accelerating is like this, otherwise the scooter runs perfectly. Can someone please give me a hint what I can still do to make the start and speed up better again? Thanks and greeting Superpuk
