As I was a classic engine mechanic (carburators) for many years (ago) *haha*
it's a simple physics problem:
If you let the cylinders shrink faster than the pistons (often in descent happens to not only stupids)
you'll get mayor problems beyond repair!
If you have a nice warm-up and claps half-closed, open them slowly in climb to keep both in a kind of "scale" v-i-v
The only model I know (but not own myself yet) simulates this is the fantastic SF 260!
If you want a close to perfect Trainer Aircraft get this.
But be a bit careful if you do:
It dismantles itself very realistic in too close turns and rolls!
