    there are 3 screws on the carb. how do i adjust this thing? The idle is a little high and i am not sure where these screws should be adjusted to. The machine was out of service for 6 years. I just replaced the fuel line and cleaned the carb, she starts but not running correctly. It is a s-25 trimmer. Thanks
