And what country can preserve its liberties if their rulers are not warned from time to time that their people preserve the spirit of resistance? Let them take arms. The remedy is to set them right as to facts, pardon and pacify them. What signify a few lives lost in a century or two? The tree of liberty must be refreshed from time to time with the blood of patriots and tyrants.

I'm not so sure it's safe to stand so close to that monster.
A rich mixture burns cooler so on the ground you leave the mixture control in 'Rich', open the cowl gills, monitor your cylinder temp gauge and adjust your mixture accordingly. If you leave it too rich for too long you'll foul all the plugs which then have to be removed and cleaned. If you let the mixture get too lean, cylinder temp will rise too high and you'll get pre-ignition that may destroy a piston.
When running an engine in a test stand, a stubby wooden "prop" is fitted to provide cooling air flow over the cylinders. He doesn't have any airflow for cooling so he can't run it long and I'll bet it is running hot.
Wife heard the audio and asked "Is that a car?" No, it is a round aircraft engine like your mother used to fly. "Oh wow!" MIL was a WASP during WWII and the AT-6 was probably her favorite aircraft. She continued flying until she was 88. RIP Grandma Fran.

Two unique things about radial engines, the sound and the smell.
