I have adjusted the linkage according to the manual to prevent over speeding of the engine. I have the carb idle speed screw adjusted. I can push down on it and the engine will slow, but then the governor slowing brings it back up. My arms on the governor have a lot of paly in them. Could that be the problem? Other than that, the governor works as it should. Thanks!

If working as it should, it should not be over speeding. Centrifugal force works against spring force. Those worn arms are lessening the spring force and I suspect, allowing it to speed up.
I am a bit surprised that the smarter n'me people haven't shown up. I would be tempted to locate a bronze bushing and minor machining to fit it in to eliminate the slop.

I solved the problem. It was not the governor. The bolt that holds the lever assembly to the lever rod, was stripped and allowing it to move. Replaced the bolt and it idels as low as I want it to. Thanks for the input. Was a bit surprised that no one else commented, but all is good!
