Carb and manifold icing is simple physics, clearly spelled out in all

BRAGGING about their ice-proof engines, as if the laws of physics
don't apply to them. (Which is really kinda scary when you think about
it. I mean, these people are allowed to breed and vote and share air-
space with normal people... )

There's a particular type of homebuilt out there that does not have a standard
carb heat setup...it apparently just uses the ambient air in the engine
compartment. It has an accident rate due to carb ice that's over twice that of
the overall homebuilt fleet.
