Feel like a Dummy-I'm new to blue, always had Honda in the past. How the heck do you adjust the Pilot Screw on a WR426/01. I looked in my owner's book and it looks like you need to remove the top of the carb. to get at it. Want to adjust the air/fuel mix and can't belive need to take the top off. Still have a POP when I let off the throttle and want to try adjusting to maybe solve the problem.

Bottom front of the carb, right in the front center. You'll need a small flat screwdriver to fit in there.

Adjust 1/4 turn at a time. A little bit of pop is ok.

That is a fuel screw, not an air screw like on 2-strokes. Yzernie is right on the money. Why you think you have to pop off the top of the carb is a mystery to me. The only reason to do that would be to change the needle...or slide. The pilot(fuel) screw is located in a recessed round tube-like area at the bottom of the carb on the cylinder head side...not the airbox side. If you get one of those little mirrors, you can locate it easily for the first time.
