Gosh, this is getting close to being like a political or religious argument.

Just in case one of the "fly boys" does not chime in, here's some information on carburetor icing and heat. Seems the problem is greater in carburetted aircraft engines than in fuel-injected engines.

One of the reasons that updraft carbs were commonly used in early engines was supposedly to eliminate the problem of fuel droplets forming inside the intake manifold.

Maybe the thermostatically controlled damper was placed in a standard 216/235/261 intake/exhaust manifold combination because the exhaust manifold was directly bolted to the intake manifold and the proximity of the two manifolds allows adequate heat transfer when the valve is closed. Thus, there is always heating of the intake manifold in the standard set-up?
