#1. yes they can be spaces back with minimal effort. the holes are still in the rack to go back to 780-800. #2. 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

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.
