On the burn out at the end of the day, I use a low throttle setting (fast idle), but then again all of my engines are YS 4-strokes. A full throttle dry run would be very dangerous on a YS and probably other 4-strokes, as it could cause the engine to seriously backfire, throw the prop, or even break the engine.

The procedure I use is shut down engine, pump tank dry, restart engine and let it run dry at idle, then attempt to restart again until I get about 2 seconds of cranking with the starter and no fire in the engine. I'm sure there are other rituals that work well for other pilots, but this seems to do the trick for me. No problems with rust, easy starts next flying session, etc.
