Dean, I think we are in agreement and I'm not sure how the wires got 
crossed. My original claim was referring to engine oil thickening as the 
temperature drops. Obviously if an engine has been sitting out in -20 temps 
for hours it doesn't matter much if it is windy or not , the oil will be 
extremely thick.
What I was making reference to was that a warm engine will cool off much 
faster if it is parked in the wind as opposed to one that is parked in a 
shed or sheltered area.
The term "wind chill factor" refers to heat loss. Humans (and warm engines) 
lose heat much quicker when they are exposed to the wind.
And I'd agree, wind chill factor has little to do with carburetor icing. Its 
the humidity.
