What is the battery voltage when you turn key to start? If it stays above 9 volts, battery , cables, and starter ok.. Remove the spark plugs and see if engine will now spin, may have liquid on top of a piston. If voltage drops at battery below 8 volts, battery , cables or starter is bad.

If no voltmeter, go direct to the starter solenoid, and jump the battery terminal to the single switch wire n the same solenid, and see if engine cranks.

Voltmeter shows no change stays at 12.7 shorting wire from positive on battery to small red wire on starter and motor wil turn and start

OK, check the switch wire voltage from keyswitch to the solenoid, when you turn key to start. Do you get battery voltage to the switch wire? May be a bad key switch.

Customer: replied 4 months ago.
That shows 15 volts
Expert:  Curtis B. replied 4 months ago.

15 volts? at the starter solenoid switch terminal? If so, replace the solenoid!

Expert:  Curtis B. replied 4 months ago.

If keyswitch sends voltage to the solenoid, and the solenoid does not close, solenoid is bad,

Any auto supply should carry a mower solenoid/relay.
