Walmart has a screwdriver on a spring which bends and comes with different sized flatheads/Phillips. I bought one last week and it fits perfectly. NAPA has one too, but you will need to get your own hex-flathead inserts yourself. Also, you DO NOT need to remove carb to adjust screw. Worst case, just remove the air filter housing bolts (2) and disconnect hoses at the bottom of housing on back side. Then push it towards the handlebars to get it out of the way. Screw is indeed hard to get to. Before I got my spring screwdriver, I would make a small adjustment with a short thin screwdriver, then put air filter back on, test. Repeated as necessary. FYI, my Kawa manual states 1 3/4 turns out, but that is only a starting point. Good luck.
