Jay, sounds like your Decompression release on your CV15 is shot! Do a compression test! When your pull that engine over is should only have about 75-90 psi. If your getting a reading of 120-150 psi then the decompression release mechanism on your Camshaft is shot or at least severly worn out. Pull the valve cover off the engine and make sure that both pushrods are still where they are supossed to be. It is very rare for a CV15 to shear a flywheel key, but you may want to check that as well.

The newer Kohler units have an automatic compression release
mechanism mounted inside the engine on the valve camshaft.
If that mechanism is not working these units are very very
hard to pull over. The mechanism came apart on my unit. The unit ran fine once it started but it was not useable.

One thing I have not seen anyone mention is the possibility of a bad compression release mechanism on the camshaft. Not something very simple for just anyone to fix but it is a possibility.

I did one of those last month, it was real hard to pull over when starting (like impossible). im willing to bet that the automatic compression release on the cam shaft is stuck and not alowing some pressure out of the combustion chamber so you can start it. if you take the spark plug boot off and it works fine.... fly wheel key, if it still kills your shoulder its your decompression release.
