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.

Ferm,
So you are saying I need to install the "smaller of the 2 sets" which is the 1 5/16 ? Note I have the larger currently installed 1 3/8 just wanted to be sure. Thanks

I would leave the ones on it on there if it were me. I'll try and do some more digging later and see what it should have on it though. If it stops raining I'll go out and measure mine since my 140 has a set of 86-early 87 140 carbs on it with those numbers.
