Even when I move the End point limit further up (Carb slightly open) the radio still exhibits this behavior. Digi-Trim has no effect on the throttle unless I advance the throttle 2 clicks.

In addition to that the throttle cutoff switch only pulls the throttle closed to whatever end point you have set for it. So, if you have the carb slightly cracked the cutoff will only pull the carb to the slightly cracked position.

I appreciate the response....... if you have any more ideas I am all ears.......
