Questioni have a John Deer with a Kohler Command 13. Model #CV13s Family#SKH398V1G21ZB Spec#21509 Disp#398.
My problems is when I throttle up, it is going WAY to fast. I have attempted to adjust the linkage.(W/ no success) I clean the carb out very well. And It just seems to throttle up way to high. Was successful at adjusting the low speed idle. It will now Idle peacefully.
Any Ideas as to why this could be caused by. Could it be something internal?
Thanks For your time and attention.
AnswerHello Joe:
>>The Following is an Instruction File I Made for Setting the Governor Arm Correctly. Any Input is Appreciated.
>>If you Removed/Loosened the Governor Arm from the Governor Shaft or Put the Linkage in a Bind when the Carburetor was Removed, 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.**
>>The Following is a Basic Instruction File for Examining the Inside of a Small Engine and will Assist you in having Access to the Governor, Oil Pump (if Applicable), Cam and Crankshaft Gear. Any Input is Appreciated.
>>**This is a Simple Process. Drain the Oil and Remove the Engine to the Work Bench with the Oil Pan Facing Up. I have a Wooden Rest that was Especially Made to Hold the Engine when in this Position.
>>Using Fine Sand Paper, Remove ALL the Rust and Debris from the Crankshaft.
>>Remove ALL the Oil Pan Bolts.
>>After All the Oil Pan Bolts are Removed; Tap Lightly on the Sides of the Oil Pan to Loosen it from the Dowel Pins.
Sometimes you May have to Use a Flat Screw Driver or Chisel Between the Oil Pan/Sump at the Areas Neat to the Dowel Pin and Loosen the Oil Pan/Sump.
>>When the Oil Pan is Removed, you can See the Governor Resting on Top of the Cam Gear.
>>****If Required: Lift Off and Replace with a New Governor. Check the Engine Block for Debris from the Old Governor and Wipe the Inside of the Block With a Rag, Until Clean. Set the Governor Shaft So it will be Resting on the Governor whine the Oil Pan is Replaced and Carefully Replace the Oil Pan. If the Crankshaft Seal Was Not Leaking, then Leave it Alone. It Should be OK. You can Easily Replace it While Mounted on the Machine if Required Later. Make Sure the Governor Stays in Contact with the Governor Shaft while Replacing the Oil Pan. Re - Mount the Engine to the Machine. Refill With Oil. Your Internal Governor May Differ.**

Then Select the OEM (Kohler) and Enter the Model and Spec Numbers (CV13-21509). Then Double Click on the Model in the Results Area. Now you can Select the Section of the Engine you Wish to View.
