Hi, With my problem it will transition pretty good when the low end is out only about 1/4 turn. If I tilt in in any direction WO or idling it runs great for a whole tank but after I'm in the air it will stall after about 30 seconds. My engine is used and I only have it a week. I never had a problem like this before. Do you have any thoughts ? Could it be anything else besides the needle?
