Engine exceeding RPM after rebuild?

[ran007]

Hey guys,
I spent some time recently rebuilding my Kohler Command Pro 21.. Cleaned carb, replaced breather tube, changed fuel, oil & air filter, and just generally made it look like new. I also noticed that the throttle on the carb was a little sticky in the process, so I cleaned that up and lubed it. Finally, I adjusted the throttle assembly mechanism arms and springs - and I think I went too far.

Well, the engine cranked right up, like new even, but the second I increase the throttle, the engine feels like it revs up waaay too high and too fast...

Does anyone have any experience with the throttle assembly mechanism, or know if what I did could have caused my problem?

Thanks for the help!

get engine model/type/etc. # off engine plate. go to kohler website. D/l service manual. May contain detailed directions for carb adj/troubleshooting.

Yeah, I have a service manual. I'm thinking that the governor lever simply needs to be reset and re-torqued correctly. I took that stuff all apart to clean, put it back together not really noting the settings.

Near the end of section 5 of the service manual will tell you how to adjust the governor.
