Can I use BN40i-38-26 and -27 carbs vs the 40i-38-29 and -30 that is OEM? The carbs look the same. The only difference I can see is the jet size. The factory spec on the OEM Mikuni 40i-38-29 and 30 dual carbs for the high speed jet size is 142.5/145 for the mag and pto carbs. Can I use the 40i-38-26 and 27 carbs with 140/142.5 sized jets with out any problems? Is anything else different?
