Excellent input from Yard Dart. Where I was only using the pinch test on my two-strokes, I think that running full throttle, then going rich till it blubbers, THEN going lean till it peaks again is a valid approach, which I will now follow. It is so much more precise than just a pinch test. Then the nose-up test fine tunes it in.
As far as the engine failures Adam is/was having, with the number of hard landings you had, it is IMPERATIVE that you hold the plane nose-up and SHAKE vigorously to jar the clunk to the proper position, or the engine will quit in flight. With all the good input since your first post I think you will have consistent good flights unless the engine breaks.
