It was much easier in days gone by when you could set it by ear.
After the simulated failure and simulated shutdown:- Mixture back up to rich, MP up til you get the borderline of the whooshing sound as the prop starts to bite. Pitch position irrelevant due to power being below governing range, but full fine is the tidiest position and best for a rapid recovery.
Works all weights, all conditions and is as near as dammit to the book settings, without gumming up the neurons with numbers.
Pity you can't do it that way on these new fangled dangles. Life was much simpler back in those days. Those days when maps were paper and not glass, didn't stop working when you dropped them on the floor, and the batteries never went flat. Those days when full reporting was the norm, and we had ops control, and Flight Service to keep an eye on us. Those days when we graduated to bigger things, there was a hairy autothrottle and systems manager sitting behind (electrons not required, just beers later)
