Jim, went out with david and adjusted the low end and it flew flawlessly. I also changed all of the fuel lines, put a new OS F plug (the right one this time), added a sullivan fuel filter and changed to a APC 16 X 4W. I'm really not for sure what it was but I think I got the grimmlens out of my motor. Flew a couple of flights and it flew flawlessly, just wish the pilot had a bit more ability. David and I had to screw the low end all the way and back it out about 3/4 of a turn and it may still be a little fat on the low end. I think I'll fly it like it is and let you tinker with it when you get out here Sept. 17. Have you talked to Don about coming out for the fun fly? I will e-mail him sometime next week. David was that not an amazing mid-air I wish I would have had a video camera. But on the other hand I feel sorry for those two. And to everyone else I sincerely appreciate all the input and help you have contributed to solving this problem!
