Just wondering if some one could help me out by telling me the factory settings for the air/fuel screw on a '04 ex (how many turns out). Thanks ahead of time.

no its not on the side its on the bottom. the one on the side is the drain screw for the bowl.

(smacking self in forehead) oh maybe thats why the thing is leaking like crazy! Can you or some one do me a REALLY big favor and take a pic of where it is on the carb please? Pathetic huh, lol.

I don't have a pic available but i'll try to explain...

It's on the underside of the carb on the part inbetween the carb bowl and the cylinder. It is more visible from the right side of the quad BUT looking from the left side it directly behind the bracket that holds the idle adjust screw.

One more question, since i backed that drain screw out 2.5 turns do i thread it all the way back in or do i have to have it backed out some?
