Sorry Gengis ... it was the way you wrote that made it look like it was the first time you had experienced it. I know you would have known about it of course.
I see your point about throttle wide open, and I guess that probably is the best as your options are increased. However, many a well set up forced landing has been ruined by an engine stuttering back to life at the wrong moment ... hence "switches off" once committed.

My mate with a Zenair 701 has a Rotax 912, it often stops as he rounds out due to its inability to tick over smoothly at speeds low enough to produce no thrust. He prefers that to a higher tick over, the reason is as demonstrated by Gengis. And yes they do shake about a bit at low tick over don't they?
