History of "Carburetion Day"

Known for many years as "Carburetion Day," and shortened only in fairly recent years simply to "Carb Day," it refers to the day on which cars qualified for the starting field are given the opportunity to practice in "Race Day trim," as opposed to the less-economical setups required for out-and-out speed during time trials. A major portion of this used to involve adjustment to the carburetors, but even after the introduction of fuel injection in the late 1940s, the original term "carburetion runs" continued to be used. For the record, the stock-block Ford-powered Lotus cars of Jim Clark and Dan Gurney in 1963 were the last to actually use carburetors on Carburetion Day.
