Lown are you sure it said to turn it 4 to 5 out on the high speed needle value for a rich setting starting out? I thought the book said to set it at 2 and 1/2 for a rich setting. I will check again to make sure though. I have a feeling that I will have to carry extra weight to the feild now to get it started but man do I love this engine. I have a 14X6 prop on the thing and it pulls my sig 4* 60 off the ground like a rocket. Thanks for the help
