[AT] Carburetor Icing (Off Topic)

[Mattias Kessén]

the difference is one is a live object the other one is dead. this gives
that the live object has it's own heating trying to keep it at 37 degrees C
(somewhere below a 100 F I'll stick to C because that's the most natural
when we talk about freezing points, though the freezing is irrelevant when
talking chilling or heating and that's what we're doing, huh?) If you on the
other hand have a dead object like a motor it becomes more like a live
object when firing it up. It will try to reach a certain temperature, in
most cases you will have to cool it. When cooling most radiators uses the
wind chill effect, if not plese explain what that fan is doing there behind
the radiator?

Some hasty thoughts, cause I don't really want to particapate in this mess,
But many have been comparing apples with oranges and many have been wrong
and many right, so am I.
