Craftsman riding lawn mower starting problems

I am having an issue starting my Craftsman 18 hp Briggs engine riding mower. Starter grinds as if battery is dead or low.

I checked the battery and it checked good, 12.5 volts
Replaced the starter, still same problem
Replaced the soloniod, still won't start same problem
Jumped start to the start from positive side of the battery same issue
checked ground wire, positive wires, soloniod wires insuring they were all tight, still same problem
Remove key switch assembly, cleaned with electrical cleaner both the switch terminals and the wire harness connector, not change.

Out of ideas, turn the key starter grinds but will not turn over.

Any thoughts on what to check next?

Can you turn engine over with spark plug out? Take plug out to see and to make sure the cylinder is not full of gas. If full of Gas the fuel shut off on bottom of Carburetor is not working or key was left on.

Also, you can't judge a battery's condition just by the volt reading. Try turning the engine by hand. Will it turn? If not, try without the spark plug as mentioned. If it does turn by hand, you might want to load test the battery.
