well i would start by screwing both screws in LIGHTLY untill the stop (clockwise) then you should have H,L stamped next to them,or under... anyway turn both screws out only 1 and 1/2 turns..it should start there, and your L screw is for idle mixture. and H screw is for High revs mixture,pr full throttle..you can play with either,untill you can hear it revs smoothly .. hope that helps. ;o)
