Excellent lesson. The instructor mentioned something I was waiting to hear and have not otherwise. That is, that upon passing through the Venturi the accelerated air then expands into the larger diameter portion of the flow passage / throat of the carb. Am I mistaken in thinking that it is this expansion of the air that causes the cooling - just as a compressor driven refrigeration system works? Much text in sources refer to the 'acceleration of the air' through the narrowed region that causes cooling...that doesn't seem to jibe with physics. TIA

So why does ice form at lower rpm when higher rpm has a much greater airspeed through the Venturi which results in even colder temperature?
