Was looking up carb parts for my 1981 115 Johnson and noticed that the same year 90 hp has a larger high speed orifice number than the 115. Wouldn't the larger hp have a larger orifice number? The 115 is a size 60C and the 90 hp has a 65C while the 140 hp has a 67C. Isn't the higher the number the greater the fuel flow? Why the larger orifice number on the lesser hp?
