I have a lawn tractor with a Kohler Courage engine. Recently the engine began surging and after looking for guidance I adjusted the governor as per kohler manual. Since I made the adjustment the engine revs at full speed on both low and high settings. I have also reset the throttle cable but there has been no change. Any ideas on what my problem is.
First guess is you misread the instructions.
