OK, anybody have a plausible theory on how adding carb heat will  
REMOVE the water?  Just making it vapor makes it combustible???

I recall reading in some flying magazine article about having to use  
carb heat (seems like it was partial carb heat) in a C172 during  
heavy rain.  If my memory is correct (not necessarily guaranteed)  
that was for a specific C172 model and engine combination.  Later  
models of the C172 did not have this recommendation.  I don't  
remember ever seeing a similar recommendation in the Lycoming O-320  
or O-360 powered Pipers or Grummans that I flew. Maybe I should look  
through the old POHs that I have in my library.
