The mixture lever in the Spits and Hurricanes is now finally correct, thanks to the determined and knowledgeable efforts of their aircraft advisor, IvanK.
The mixture lever is mechanically linked to the throttle. When the throttle is fully back, the mixture lever is forced to remain fully back in its "Auto-Rich" position. For virtually all flying situations this is where it should remain -- takeoff, climbing, diving, combat, even general level cruising. When the throttle is moved forward, the mixture lever is then mechanically able to be pushed forward into its other position: "Auto-Lean". There are no intermediate mixture settings in the Spits or Hurries, it's just one or the other.
When to use Auto-Lean? Generally on extended patrols or CAP duty over shipping in the channel. Here boost absolutely MUST be reduced down to less than +3 lbs (using throttle) and revs maintained in a moderate setting of 1800 - 2200 rpms (using prop pitch) in level flight only. The first hint of trouble: pull mixture back to Full Rich, increase revs to 2600, and push throttle to 100%.
I have the same prob with the undercarriage control assigned to an axis on my CH Quadrant. Sometimes it doesn't "take" the first or second time. Must be a glitch.
