Silversurfer thanks i will try and set it the way you explaned got to get me a short screwdriver to do it but sounds like the way to go, now i have just been adjusting then shutting motor down to make adjustments , motor is on the plane and has 2 gallons thru it. Runs good except for the midrange , could be it just needs some time on the motor also, i will let you know later today how adustments work out. Thanks Bruce
