1987 140 V4 Looper Carb Question

[Skools Out]

the 120's and 140's have the same carbs only difference is the reed set and jets, a 120 has small throat reeds and the 140's use the same reeds as the upper 225's had. I've converted several 120's to 140's by changing the reeds carrier and reeds to 225 uppers plus rejet to 140 size jets.
