Ya carb was completely disassembled, cleaned very maticulously. Not a rookie at this stuff just stumped on this one. Why does everyone say to remove all freeplay from cable??? 2mm are you measuring the air box side of the carb where the slide meets the body[ where the jet needle sticks out of body]? As far as the air screw it does change the throttle response but still will not idle.. 1 1/4 out  bout as good as I could get it. Any leaner more turns out had a nastly lean bog, more turns in responded very slugish.
