Also internal intercooler icing which severly limits the benefit of turbocharging and intercooling. Theoretically, you could have -40 intake temp with an efficient intercooler, however cooling the air that much freezes any liquid in the intercooler. You basically have to keep temps around 5-10 degrees, robbing you of a lot of free power.
I have had carb icing on a downdraught butterfly carb on a motorcycle. However, the issue that I had is not one which I have seen any mention on in the aviation scene. My issue was not that the throttle was choked, the issue was that the ice didn't allow the throttle to close. This meant that I was able to ride in 4th at 30mph on a "closed" throttle. I surmise that the ice built up on the sholders of the valve meaning that the butterfly couldn't fully close.
Crappy 1950's technology. Carbs, ice, lean/rich mixtures adjusted from cockpit. Disposable air filter sitting in jetted air, then needs warming the air? Intake manifold prone to leaks. Then ventilation flaps controlled from cockpit. Get a life Lycoming and Continental. It is 2023.2 Ecu;s Dual fuel injection per cylinder.
More accurately 1930's technology. By 1940 aircraft engines already had liquid cooling and fuel injection. US technology is far behind, they still believe this is high tech.

Not entirely their fault since the fan makes certification for new systems so difficult and expensive it’s more economical to use these old systems
