Ok, Your reply told me that I might not have a problem with my gas carbburetor which I wasn't sure about..... and to look at my linkage setup.
You might be right as I have taken off a ZDZ 40 where the servo is hooked directly to the throttle arm and mounting on my Brison 2.4 where as you know has this nice linkage to move the throttle arm. The geometry has changed.

I will get the plane out of the trailer today and also look at my computer transmitter and see if I have the throws set to a 100%.
Thanks
Jim
