Carb: Adjustments?

Set both screws one turn out from closed, start and warm the engine adjust the L screw first this will adjust the mixture from idle to half revs, unscrew to richen the mixture, when you blip the throttle and have good acceleration stop adjusting, adjust the idle screw for good tick over, the H screw will adjust from half throttle to max revs, this should be checked with a tachometer, engine over speeding can cause engine seizure
