Tim, there is very little actual difference, other than the California emission standard for any given model year were tighter than 48 State, so expect a leaner calibration across the board, if comparing carburetors by part number, for example 17059206 vs 17059506, etc......Cliff
Are the leaner "cailbrations" are in circuits that can be recalibrated fairly easily?
