That's pretty much the explanation I've heard/accepted. I'm not too familiar
with the Cont. induction system, but I think the carb body isn't heated by bolting it
to the oilpan. I've gotten carb ice in my Lycoming O-360 a couple of times... usually
in classically expected conditions (40-50degrees, foggish, low MP at low altitudes so
lots of expansion)
