Why does novarossi say to replace the aluminum rings around the hsn when moving the fuel inlet? I downloaded the factory carburetor settings and it says to replace the aluminum gaskets if you move the fuel inlet. Any reason why? they are not damaged just by loosening the needle housing i dont think.
