Glenn spotted this one.

“I have used Monarch Governor that was on a Willys 134 L-head engine. The govenor works with all the Willys vehicles that had the 134 L-head engine. The govenor works like a cruise control, the engine speed is maintained at a preset value regardless of the load applied. They were commonly utilized while running PTO driven equipment.

The last picture is what they look like installed. I do not have the contol cable and rods other than what you see on my governor.”
