With the the 340 warmed up and running,I loosen the lock screw, then turn the nut ccw to raise the float. Nothing happens. Why?

The nut then turns and nothing else. Take the screw off, remove the nut and then the gasket. Then put the nut back on with no gasket and unscrew the needle assembly out a turn or two and re assemble it. 2017 Contusion Blue Challenger T/A 392 M6 "BLKNBLU"

The square sides of the needle valve actually chewed into the square sides of the nut, and caused the slip. Can't believe that the brass needle is harder than the nut material. Com'on Holley! Thanks guys.
