won't restart

Yesterday my craftsman mower just died while I was driving slowly around the yard. It has a kohler cv14s 14hp engine.
I have since put in a new
spark plug, air filter, fuel filter and changed the oil

I tested the spark plug and it sparked.
I tested the fuel carburetor solenoid and it depresses when I turn the key.
I have fuel up to carburetor bowl.
It won't start when I spray in starter fluid. It seems to try, but not really.

I sprayed out the carburetor. In each orifice, I sprayed brake cleaner and it squirted out somewhere else, so all passages seem open.
gas tank is full


Engine cranks just fine. When I start it in gear, it wants to roll forward, so I think the flywheel key is fine.

Any help would be appreciated.
