So I got this carburetor repair manual from a company called Rochester, who have been a division of General Motors from like the 30's to the present.  Since like 1990, though, they have only made fuel injection stuff.  So the book I have is from 1956, and it details the repair and rebuilding procedures for the carburetor on my old tow truck.  So I was reading this the other day, and in the beginning of the book they explain the basic principles of a carburetor.  To put it simply, a carburetor is the thingie on the engine that mixes the gas from the tank and air from the atmosphere, and this is what burns inside an engine.  So in the book they have this dopey picture of these big fat while globs with the word 'air' on them and these little black globs with the word 'fuel' on them, and theyre jumping into this giant funnel.  That's the technical diagram?  Nevertheless, I read on, and the good people at General Motors went on to say that a carburetor must perform its duties in a multitude of conditions, from frigid temperatures to sweltering heat.  To demonstrate the cold theory, the show a brand new 1952 Chevrolet driving apparently in northern Alaska, because it is being driven by eskimos, in full fur dress and hoods, who are waving to more eskimos dressed in the same fashion, and drawing the attention of yet another eskimo crawling out from an igloo.  Did people really think that's what went on in Alaska in 1956?  Eskimos would go hunt an elk for 3 days, skin and tan it's hide, then decide to crawl out of their igloo to go for a quick spin in their new Chevrolet?  Then, to make things even more uncomfortable stereotypical, so show how it would work in hot temperatures, there is the same brand new 1952 Chevrolet with it's top down somewhere in the Middle East.  The car is being driven and uccupied by several Arabs, all of them in traditional Middle Eastern dress, turban and cartoonish moustache and all.  And once again, waving to a gentleman wearing a jockey's cap piloting a camel with a number on the side of it across the desert dunes.  I know that as a society is doesn't look like we've advanced that far, especially in this time of censorship about the war, but I figured I'd just tell everyone about this little slice of history so show that we've at least come a little bit...I guess.  Although I'm sure there are still plenty of people who think that this nonsense goes on...oh well.
