Beats me! The 140 pilots were talking about it. That's one of the reasons I want to install a temporary gauge and do some experimenting. I definately believe it can help detect the onset of carb ice, even before a power loss is evident. I think it might help set mixture, since the amount of fuel in the mixture can affect cooling of the induction air, and therefore density and breathing, which might show up ever so slightly on the gauge. One thing that puzzles me, is why (from what I'm told) Cessna hooked the gauge to a boss on #2 cylinder, above the intake valve. Seems like that would cause a flux everytime #2 intake opens. I'm not about to drill and tap a hole in my cylinders just for an experiment (the boss is there, just not used. A holdover from the old fuel injection system, I think). I'll tap into the induction spider, instead.
I don't expect any industry standard revelations here. Just covering old ground our predecessors thought worth the effort.
