I will pull them apart tonite and see EXACTLY what jets are now there. You would want to check with someone with more knowledge than I on what stock Mach Z settings are, and if these will work as is or what if anything to be recalibrated. #3. i am happy to hear that you really need a set. I really need to SELL this set! Back with you later tonite. Thanks! Andy

have they been bored or are they stock 38

have they been bored or are they stock 38[/b]They have been bored. These carbs came from Chuck Walters. Ski-Doo Master from Lewiston,MI. Needle Jet= 8AGY-41,center postion. Tubes=327-04. Mains=440,450,450. I stand corrected on my initial post. These appear to be jetted for the 780-800.

Who wants the 40 flats?
