Good post, and good reminder. One comment. As I understand it, carb ice
is most common on warm (70 degree or so), humid, days. As the
temperature drops, so does the moisture in the air.


The most ice-susceptible air, I have found, is that between 20F and 55F,
with very high humidity -- not to say that a higher or lower range would
not cause ice.

It is good practice to install carb heat and USE it -- especially in
high humidity conditions.
