Hello Greg:

If you are Sure All the Bolts are Removed, then Clean the Crankshaft with Fine Sand Paper and Remove ALL the RUST and Debris from the Crankshaft. After All the Oil Pan Bolts are Removed; Tap Lightly on the Sides of the Oil Pan to Loosen it from the Dowel Pins. When the Oil Pan is Removed, you can See the Governor Resting on Top of the Cam Gear. 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 So it is Resting on the Governor Shaft and Carefully Replace the Oil Pan. Remember to Replace the Oil Pan Gasket. 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. These Instructions are Basic. Your Internal Governor May Differ. 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. Have a Happy Holiday Season and May the All Mighty Bless You and Yours. Be Safe and Happy. Thanks.

Good Luck
