    Well, moved sensor to correct side, installed engine, and now starter will not engage. Fuel pump cycles, lights on dash come on, but no crank! I'm ready to burn it down!

    Loose or broken wire when you reinstalled. Check the fuses. Check battery voltage.

    Battery gauge on mower display goes to 12v with key on. I shorted starter and it will spin but doesn't engage.

    That indicates a bad starter bendix. One thing after another with this engine. How confident are you pulling a starter apart?

    Slow down....and recheck your wiring....
    The starter engaged before the last adjustment...
    Battery installed correctly.??? Fuses ok..???...any extra wires..
    If the battery is hooked up backwards. The starter will spin but won't engage...
    Its got to be something simple...

    Battery is installed correctly, fuses are ok, and there are no extra wires. Turning the key to start does nothing and shorting the starter will only make it spin, it doesn't engage flywheel (shouldn't shorting the starter make it engage and crank engine over?) How should I determine if its the starter or just an electrical issue? I have VOM but electricity is not my strong point. It would be my luck that starter went bad in between me moving sensor to correct location :(

    Check the ground cable on the battery..
    Check battery voltage...check it again while trying to crank..
    Check the voltage to the frame mounted solenoid...yellow wire should have 12v when cranking
