I understood what you were saying, the first two numbers are the port and starboard carbs for the 86-early 87 140 as they were jetted differently on each side. The second set of numbers are for a completely different set of carbs as the upper 4 carbs are one number on the 225's and the lowewr 2 are another number. If you have those 2 numbers both attatched to one throttle body, then they are most likely a pieced together set. Also some of the early 86-87 225's if they were short shafts got the 200XP carbs. I would stick to the smaller of the 2 sets which are most likely what should be on it. IIRC 120 carbs are 1 1/8", so 1 3/8" should be 140's.
