I'm overhauling my Kohler 14hp as we speak, noticed the throttle shaft in the carburetor was getting pretty worn and loose. It ran fine before but a leaking throttle shaft can mean a bad idle or other quirks. I took the two tiny screws out of the throttle plate & shaft, pulled the shaft out. It was worm and so was the bore in the carb' so a new shaft wouldn't have helped much. I clamped the shaft in my vise, used the torch and laid a little brass on the worn bearing spots. From then on it's a matter of a good eye and some smaller sharp files. I worked the brass down and kept fitting the shaft into the carb', it finally went in and fit really well, put the plate & screws back in and ... we now have a nice snug throttle, no air leaks, great idle and steady governor control. Also no money spent, no time lost waiting for parts that wouldn't have worked well anyway.
