I thought with EVO you could not make any changes to the carb other than Main, needle position and idle air screw. I thought inner and outer pilots, floats etc. were all fixed (float height ok within the legal range. I was told that for micro anyway. odd deal though is the smallest jet made for the carb ia a 112 and will probably be too large for micro but thus far the range of legal jet (115-130) for micro are still all that will be legal. Micros will be crazy rich is my guess.
