We have a guy at our field that is ALWAYS trying to get his engine running "perfectly". He will spent hours trying to get the top end and idle set just right, only to have them die in flight. If you want to know who to get tuning advice from find the guy at the field that goes out, starts his plane, taxis out, flies, lands, taxis back, kills the engine, and then heads for the stands to shoot the breeze with his buddies. You want him because he has learned to tune his engine correctly and then LEAVE IT ALONE, and just flies. You really need to make a decision, you can spend all of your time tinkering and worrying about getting the engine set correctly, or you can just set it and fly-- and have more time to spend with your flying buddies!!
