I have a Kohler Command CV14s ( on a John Deere Tractor ) am stumped as to what is going on. I can start it and it stays on idle and is fine, when i move the throttle even a small amount the thing throttles up like it is out of control , way to high . When you watch the throttle control on the carb it only has to go a small touch after the low idle to rev so high. The govenor is working properly and the spings and stuff. You can control the idle , but it seems as though it is letting WAY to much gas in and reving way to high. Any suggestions on what to do ??
