FOUND IT! Bushing/Gromet Kohler Part Number 25 158 08-S. good luck. Hope you never need one!I'm talking about the nylon gromet/bushing that the gov. linkage rod attaches to the carb lever.
Not avilable? see last post. A serch of the net yeilds many sources.Though I thick they are expensive in the 5-6 dollar range.If you see one on another carb and want to try to put it on your carb soften it in hot water to remove and then re-install without breaking.
They are not available as a repl part.
Some engines have a little long tiny spring that fits around the governor/throttle arm and holds the slack when the grommet is not used.
Sometimes you can just live W/O either one.
