I've been having troubles adjusting my originals governor correctly to get a good range of speed with the throttle. I've followed the kohler manual to the letter and am having trouble. It will speed up to about a high idle and them, with just a little more throttle, will speed away erratically. I'm usually pretty good with these so this has me frustrated. Any ideas?

I am going to take a guess and say that probably something inside the motor is broken. Maybe the weights on the gov. gear have let loose or maybe the actuator arm on the cross shaft.

I think Kelly nailed it. Sure sounds like the internals if nothing else has changed. All springs there and where they should be?

Check all the linkage for slack and wear. If something is sticking or has a lot of slop in it you can get some strange behaviour. I recently fixed up a 3.5hp tecumseh on a tiller that was acting really strange. I traced the problem to a worn lever in the linkage that was making it impossible for me to adjust it. Once I had that tightened up I was able to make the necessary adjustments and got it working properly. I hope it's not something internal!

The throttle shaft was bent at first causing it to stick. I got it straitened out and seems to turn well. Im pretty sure I checked the gear when I tore it down and know I would have addressed it if it was a problem. The cable is a little sticky so that may be a route I take. Maybe for now though, since it won't be doing much work, I'll set it at high idle and puts around slowly. Thanks for the thoughts.
