[edit] WHY CARB HEAT

The present explanation (as of 19 Oct 2007) is only partially correct, as it ascribes the cooling effect in the carburetor only to the venturi effect, yet it states that fuel-injected engines do not need CH - does nobody see the inconsistency in that reasoning? Both engines have butterfly valves. The answer, of course, is the tremendous heat absorbed by the liquid (gasoline) being evaporated at the carburetor. I have rewritten the article to point this out.Raymondwinn 07:07, 20 October 2007 (UTC)
