I apologize Mike, I had originally assumed your were an old timer like me that had built models ever since they made glow engines and your dad and uncle before that.

I've got to tell a tale about now

It was like 1950 and my dad was showing me how to set the needle valves on the lawn mower. Me being a kid and full of questions I inquired about why the throttle seemed to move on its own and not necessarily with the throttle lever. He went on to explain that there was a governor inside the cover of the engine that limited the speed but when you got into heavy grass how it would open the throttle to give more power and to try to maintain the engine speed. He removed the cover from the engine to show me how it worked.

All the while he was explaining, I was trying to see the "little Governor of the State" in the engine and all I could see was a spring loaded paddle that the cooling fins of the flywheel blew air against to limit the speed of the engine. Then latter that night I was wondering why the government would require some dumb thing like that in an engine. The government sure was being pushy. Eventually I figured it out that B&S had put the governor in the engine to keep it from blowing up yet have extra power when it was needed.

Along about then I also asked him why the bottom blade on the three bladed props on the planes when he was in the Air Force was longer than the other two? He went on to explain that the props were made that way to "drain the pitch" out of them. So I went back to my plastic model - turning the three bladed prop - trying the figure out how the bottom blade always got longer? I didn't expect any pitch to drain out of the prop for after all, it was just a plastic model. . . . .
