Oktas8,
I wouldn't agree that leaving the throttle partly open as the normal thing to do following engine failure. It may result in a perfectly judged forced landing ending up in the far hedge if the engine briefly picks up again.
Even worse, an attempt might be made to fly away from the only decent landing area, only to have the engine fail again with nowhere to go. A situation like this killed a very good mate of mine. He and his student ended up in the undershoot of a very small field, unfortunately they didn't get away with it.
