CACRWLR 0 Posted September 18, 2017 Hi, This might be a dumb question, but can you adjust the carburetor pilot screw on a '99 King Quad while the carb is on the atv? There doesn't look like there's much clearance between the pilot screw and the cylinder head to get a screwdriver in there (if I'm looking at the right screw). The engine runs pretty good; there's just a slight hesitation in the lower rpm ranges. Thanks. Share this post Link to post Share on other sites Like what you are reading?
