Small Engines (Lawn Mowers, etc.): Kohler Internal Govenor, john deere 110, throttle shaft

Question
I have a 1971  8HP Kohler engine.  I rebuilt the Carburetor, added a new spark plug, added oil to the crankcase. It is on a John Deere #110
When I started it up. I thought the engine was going to blow.  It has a very high RPM. I am trying to understand what I did to cause it. Is it easily repairable?

Answer
Hello John:

From your Description it Sounds like the Governor Requires Setting. The Following is an Instruction File I Made for Making this Adjustment. Any Input is Appreciated.  If you Removed/Loosened the Governor Arm to Remove the Carburetor, then Reset the Governor. **To Reset the Governor; Loosen the Governor Arm Bolt and Turn the Governor Shaft Clockwise Until it Stops. Using the Governor Arm Hold the Carburetor to Full Throttle. Now with the Shaft Full Clockwise and the Governor Arm and Carburetor Held at Full Throttle, Tighten the Governor Arm Bolt. If the Engine Still Runs Full Throttle, then Reverse the Rotation of the Governor Shaft, but Still Hold the Carburetor at Full Throttle with the Governor Arm. If it Still Runs at Full Throttle, then Check the Internal Governor.** How the Governor Linkage should be Connected. **The Throttle Cable Attaches to the Throttle Control Bracket. The Cable Moves a Slide that Moves a Pivot. The Pivot has the Spring  Attached to it and the Other End of this Spring Attaches to the Governor Arm. The Solid Link Connects to the Governor Arm and goes to the Throttle Shaft on the Carburetor.  When the Throttle Cable is Moved it Moves the Pivot and the Pivot Pulls the Spring. The Spring Pulls the Governor Arm and the Governor Arm Moves the Throttle Shaft. Usually the Spring is in the Lower Hole in the Governor Arm and the Solid Link is in the Top Hole of the Governor Arm.** You can View a Breakdown of the Engine at this Site Addy; http://www.kohlerplus.com/login.asp and Select Enter as Guest.

Then Select your Model from the Search Results Area. Then Select the Sectional File. Then Select the Section of the Mower you Wish to View Online. If you Hit a Snag or this Does Not Correct the Problem,  I am Here if You Require More Assistance. Hope this Helps. Let me Know What Happens, Please. May the All Mighty Bless You and Yours. Thanks.

Good Luck
