The scew marked L will adjust the fuel mixture up to half throttle, the scerw marked Ior T will adjust the actual tick over speed, set the L screw at one and a half turns out from closed, start the saw and warm it up, if it will not idle screw the T screw in until it does, start to screw the L screw in, the revs will increase as the mixture leans off, it will reach a point where the revs start to drop as it then becomes too lean, back the screw out at this point 10 minutes on a clock face, now adjust the T screw to put the idle speed correct.
