Ever adjust the valves?

I would look closely at the key stock between the crankshaft and flywheel. Most likely it has sheared.

The above suggestions are probably good. If you changed the fuel pump disconnect the output side and be sure it's actually pumping fuel. Some new pumps are defective right out of the box. That was my most recent Kohler experience.

Not the best picture but this is a screenshot of the service manual for the engine. I put a magnifier over the key on the crank shaft and circled in red where it talks about inspecting it. You have to remove the flywheel to see if it is sheared.
