Re: Whats the air screw setting for a yz 250 93model
One and a half turns out,,from fully screwed in,,,,give it half a turn in or out and when the bike idles at its highest,,you are spot on and can then turn down the idle from the idle screw.

Hi..both screws r on outside of carb your air flow screw is the bigger of the 2 with a spring on it usually by top where throttle body is.. Outher is kinda set in on same side b careful u dont loose lil washer and turn small turns to fix your issue.good luck bud..
Black spark plug means too rich , you will have to replace the spark plug since it has foul up and reset the air mixture screw on the carburator 2 and 1/2 turns outwards.
Check the air filter too.
Hope this helps.
