> There are very few carb'd cars on the road these days in the USA. Yeah, there are less, but on a summer weekend in Southern California you can expect fumes from a number of car-culture enthusiasts and their cars. My favorite : Carbureted rotaries. The smell of unbalanced air-fuel ratio plus the smell of motor oil being burned in combustion. It's like the two-stroke of the streets. Even better when it has lost a coolant seal and you get that nice sticky white-blue coolant component to the noxious cloud left behind.
