Kosa picked up today from the service and I will say yes, the tank has been replaced with a brand new one - one without a gasket. The carburetor was also replaced, but probably also with a float, because there is also a butterfly on the bottom with a scythe settler, it is probably better. It does not go like full speed, but certainly better than on the other carburetor, now the tap is turned to Full and after pressing the gas it collects faster and is not flooded with too much fuel. If you want, I can take a picture of the carburetor for you at your request. Because I do not remember what the previous one looked like, but it seems to me that the decanter was rounded and this one is so more angular.
