I have a paperback from Lindsey(sp?) Publications from the 1980s which has a dozen or so 200-mpg carbs.
The crux of it is that you push the car up to 35-mph,start the engine and engage the transmission.The car will go down a straight,level road,under perfect weather conditions,at 35 mph and return 200 mpg.The engine won't idle.It won't race.It will only work in top gear at 35 mph.
Most folks can live with that,right?
I think there is a photo of the book's cover in aerohead's aerodynamic photos album archive.
