Given that most of us are used to adjusting mixture by cranking repeatedly on the big red knob, it does take a little mental adjustment to get used to the small adjustments needed with the EC-2. But I'm pretty well dialed into it now.

Mike;

One of the nice things about the rotary with the EC-2 is; once well tuned; you don’t have to make any adjustments.  My lean cruise position is at 10:30 – 11:00; max power 2:30 – 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 – needs minimal pilot attention.
