One of the= nice things about the rotary with the EC-2 is; once well tuned; you don=92t have to make any adjustments.=A0 My lean cruise position is at 10:30 =96 11:00; max power 2:30 =96 3:00; but I can taxi away from the hangar with it at 2:00 position; do a flight to 10,000 ft and return to the hangar without ever touching the knob and it never missing a beat. Not optimum, and EGTs higher than desired; but the point is =96 needs minimal pilot attention.
