I've got a 2005 Johnson 15hp 2 stroke. Runs great, but would like to lower the idle speed. I've adjusted the screw on the front of the handle and it only makes it go higher. Looked under the cover and it looks like I need to adjust something on the carburetor. Think I need to adjust some linkages on the carb or something. Can anyone give me the procedure? Wouldn't think it would be too tough.
