Hello dear people my father has now bought a slightly newer Kymco Agility 50 built in 2019 with 6000 km used. From 2019 to 2022 he was approved as a Mofa 25 kmh from 2022 to 2025 which is now open with 45 kmh. Before that he had a Kymco Agility 50 built in 2009 with 62,000 km. Slowly he had already made some quirks and therefore he bought a used new scooter. Now the following problem occurs that he starts very hard and when he starts then The speed goes up and down slightly but not always. If the scooter has started once and I turn it off then I can start it again immediately without any problems. If I start it with the electric starter it takes a second and it is immediately on. But as soon as it stands for longer time it does not work as it should and it takes long until it starts. I wanted to replace the complete carburettor because we still have a carburettor there I have to notice that the new carburetor has screwed on completely different parts I think this is a so-called AGR valve for the environmental impact On the left side of the carburetor is something screwed for what is it supposed to be? I send you a photo with I could actually exchange the carburetor from the old scooter or what must I take into account. I have already tried to do the following. Carburetor cleaned stand gas nozzle and petrol nozzle cleaned. n what else it could be like said once he jumped on he goes to immediately again. Would I really be happy about your help
