Had a similar situation a couple months ago when a throttle connection came loose in flight. (Fliton Edge 540 Freestyle with a Magnum 91 four stroke). The plane was happily flying along at 3/4 throttle. Too fast to land, and this engine sips fuel, so I was in for a very long flight. After a couple minutes, I decided to try to get the clunk high and dry by taking the plane up as high as I dared and diving. On the third try, sure enough, the engine finally quit, and got her down safely. There was still over half a tank of fuel left.
