If a C-85 is "prop-challenged", does the prop turn up book rpm on the ground? If not, maybe the engine or the prop needs attention! At full rich and high altitude a Stromberg is being asked to do something no carburetor can do...deliver best power with a non-optimum fuel mixture, to say nothing of the fuel waste. I've heard more than a few claim the Stromberg mixture control doesn't make any difference. If it's in good condition and the holes in the disk and body are clean, that mixture control does all anyone could ask (except function as an idle cut-off, which it was not designed to do). Descended into a sea-level airport pattern from an extended "high" flight without changing my mixture (just plain forgot), when I throttled back a bit things got real quiet. As another once put it, that fan out front keeps the pilot cool, and if you don't believe that, watch him sweat if it stops! As soon as I pushed the mixture back in (immediately), all was well (prop kept windmilling). It's truly amazing how time stands still when your adrenalin "pops"...seems like you think things through forever and react like a slug at the time. In retrospect, reaction was almost instantaneous. As a separate consideration, has anybody seen a 337 to remove (or disable) the mixture control? Is your insurance good without it if your airworthiness isn't? Now I'll have to admit on that coupe the "automatic" mixture enrichment had been removed (same questions apply) or this might not have happened. I've yet to "be aware" of this actually functional on a coupe...maybe most are removed? Regards, William R.
