The Stromberg leaning mechanism works using pressure differences within the carburetor.
These differences are pronounced during cruise flight, where leaning makes sense. During full throttle and while idling, the pressure difference is not great enough to create a leaning effect. See it as a safety feature. You can not accidentally kill the engine on a full throttle climb out or on final with the throttle shut. The engine keeps running even when fully leaned out.

I pull it all the way out, and maybe a TINY change in engine sound, but oh so tiny. Heck, that is how I used to shut my Cessna 172 down, was to pull the mixture knob all the way out and starve the engine until it quit running. Is my plane unique, or is this another ercoupe thing? Any advice would be appreciated. Oh, I have a completely rebuilt Stromburg carb on my C-85 engine.
