    pilot screw

    Could someone please tell me the pilot screw setting for a 83 110 I think its 2 ½ turns out that’s usually what everything is. Also the valve will hit the spark plug when its pointing towards it so I put 4 washers on the plug for a quick fix its got a NGK plug long shank I would assume the 110 had a short shank plug???. Thanks for any help

    Does anyone know the pilot screw setting on the carb for a 125 or a 185 I just need a general setting. Is in leaner and out richer.

    Turn it all the way in - leaner - until it bottoms out genly, than back it out appx 1 and 1/2 turns it it should run or something is clogged etc. Out is richer or more gas

    Good luck!!

    Just some FYI for everyone. I've been doing a lot of reading and playing around trying to learn how to tune a carb. If the pilot screw is on the motor side of the carb, it controls fuel(in=leaner, out=richer) if it's on the back side, it controls air(in=richer, out=leaner)

    And I don't have my manual at hand, but I think 1 3/8 or 1 1/2 would be the factory setting.
