Wouldn't engage starter.

True root cause was a failed safety switch in the transmission. The switch was supposed to close when the transmission gear shifter was placed in neutral. Probably didn't need to replace the starter switch and the solenoid but they work fine.

Worked perfectly

Switch was easy to install and worked perfectly. It was better insulated than the original part. I unfortunately let the engine run out of oil so I have to rebuild an engine over this winter.
