Just an update from the field today. Engine ran pretty well on the ground, but I couldn't get it to be happy at any less than 3 1/2 turns out on the main needle. I tried one flight at 3 1/4 turns but it wasn't happy - may have been a little lean (though there was still smoke) - it died after about 4 minutes in the air at that setting. After turning out to 3 1/2 it had a happier flight. Very good transition now. I guess I'll just continue to be patient, and let the engine tell me what it likes.
