A mixture cut is kinder in the engine pistons and rings and gives indications that more closely resemble a real engine failure in a normally aspirated aircraft. In other words the manifold pressure and RPM indications mimic a real engine failure.
Closing the throttle gives a false manifold pressure indication and the throttle lever is in the wrong place for the drills that need to take place.
I've never had an issue bringing the power up from mixture cut.
Correct, it is a recommendation of Lycoming to use the mixture.
It's also very easy for a student to identifie the correct engine when there is only one throttle to play with.
We have all heard the stories of pleople shutting down the wrong engine.
I have had many students identifie the wrong engine. Glad they did it with me, not when it's the real deal.
