I'm talking about the nylon gromet/bushing that the gov. linkage rod attaches to the carb lever.
FOUND IT! Bushing/Gromet Kohler Part Number 25 158 08-S. good luck. Hope you never need one!
Thank you all for your time and consideration.

I think those are kept in the hen's teeth drawer of the parts bin. Never had to find one.
I did not look closely at the posted image, but some carb<>governor links use a thin long spring to keep tension on both ends. If that spring is missing or broken, slop on either pivot point can get the governor to start hunting as it falls behind the rpm response of the engine. One other thing to consider if you have a hunting condition is the freedom of the linkage to move. The linkage should not bind in any position, full or closed throttle. The throttle spring should go to WOT if the manual control is advanced to full throttle position. I am not directing this at you, the OP, but as a general missive.

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.

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.
