Hi Paul, Gordon, int.al.
    Why is the lever action so important? How often are we likely to adjust
    the mixture? Mount the valve on the engine side of the firewall with
    the shaft coming thru into the cockpit with an extension to the inst.
    panel and adjust the mixture with the knob. I suspect the reason we
    have mixture 'levers', is because that is the type of control on
    Lycosaurus carbs. If we retain the screw knob, it is "vernier"
    adjustment already.

    BR, Dave McC



    You mean a solid shaft extension right? That would be better than a
    cable because it would eliminate any potential slop. It wouldn't
    need to be that long to reach from fiewall to instrument panel. This
    should work well.

    Regards,

    Gordon.

      Yes, I think you mean rigid;  a tubular shaft, say, a 1/4"
aluminum tube.
      I have a selector knob on my Stinson panel connected to the fuel
selector valve on the firewall by a 5/16 tube and it works fine; for
the last 48 years anyways.
