Indy 500's Carb Day-- Part 2: The "Shake Down"
But, the Indy 500 is steeped in tradition so even though no Indy cars had a carburetor since 1963, the name continues.
Carburetion Day was held on randomly selected days the week before the big race. It was not open to the public until the mid-1950s.
In 1969, it was held on Thursday and continued intl 2005 when it was moved to Friday.
Carb Day dives teams and drivers the opportunity to "shake down" their cars and make sure it is mechanically sound.
