REFLECTOR: Low CHTs

[John Dibble]

This time of year my CHTs are low and my oil temp is also, making it difficult to heat
the cabin.  I'm thinking of putting butterfly valves in the engine cooling inlets,
similar to what is in my engine intake air for carbureator heat.  Rather than run
cables, I'm thinking of using a bi-metallic spring, like is used for automatic chokes
on cars to open and close the valves.  Ideally the spring would work off of CHT, but I
think this will be to complicated, so I think using OAT would be more practical.
Any thoughts whether this is a good idea?
