    V-4 Looper Idle air bleed oriface - which one?

    94 120 V-4 Looper, Minlon (plastic) type carbs. I'm trying to figure out a rough idle problem and I think I may have found it... there are 2 fixed air bleed orifaces, one for idle and one intermediate.

    V-4 lower unit swap standard to commercial V-4

    I have bought a 94 Evinrude 120 V-4 (looper) with bad gears due to water intrusion, but I fished the boat w/owner several times prior to failure and it ran strong, so I bought it as a fixer-upper. Anyone know if a 92 Evinrude commercial V-4 100hp lower unit w/same length shaft will swap? Looks...
