      Hi,

      the mixture lever does not have an effect in my plane. I am flying at 7250 ft, throttle at full and propeller adjusted to 2200 rpm. When I move the mixture lever to cut off, the engines cuts off as expected.

      At any value between cut off and full mixture, the lever has no effect. Neither RPM nor EGT change. I have attached 2 screenshots for visualization.piper misxture low.jpg

        Do you have automixture turned on? It's somewhere in the assistance settings, or something like that.

            The mixture lever works. Whether you get the expected fuel flow at cruise flight is a different matter, though.

              Thank you for all the replies. Yes, I was not aware that automixture was set in the assistance options!
