Yes. Most types of damage are not simulated in MSFS aircraft, nor is
cumulative damage simulated (as far as I know).

Leaning the mixture beyond a certain point does indeed stall the
engines in the Dreamfleet Baron model I fly in simulation.

In real airplanes there is a lag. Lean it out slowly. A Cessna 182
manual I remember reading said that it should take about two minutes to
find the peak. This may also not be adequately simulated in
"entertainment level" simulators.

I see a lag in the simulator, also.

I've never heard "a full turn", though I have heard the less helpful
phrase "a bit". Not all airplanes have vernier controls, and I don't
think MSFS aircraft do either.

The Baron has controls similar to the real aircraft, that is, two
levers for mixture.
