I am not a physics professor by a long shot, but I have studied this. When fuel vaporize, it suck heat from the surrounding air. This can lower the temperature to freezing. This is the same reason why water on shirt cools you. As water evaporate, it sucks heat away from you. Vapor lock is different. There, the vaporization of fuel is no were near enough to freeze the carburetor, so it just goes dry. Ben
