Ok this is for the engine tuners. I'm having a little trouble with my OS55AX throttle low and high end settings. It runs fine on the ground, but staggers through midrange. By the time it get up near top end it runs fine. I've leaned out the bottom end, and tried to richen and then lean out the top end, but If I fly around at 40-50% throttle for a while and try to rev up, the engine bogs again, and I'm scared to death of losing it. I have dome some fiddling to try to get the mix right, but I must be doing something wrong. I'm using Wildcat 15% and a #8 plug. Any suggestions? I've had several of the shade tree experts give conflicting advice, so I'll just come back here to get the correct answer. Any help is great appreciated.
