I just got the Motion Pro FCR carb tool. It is excellent. It comes with a round handle that accepts the bits, two flat screwdriver bits of different sizes, a hex bit to remove the the bottom cover off the carb, and a case. It works perfect for adjusting the pilot screw on the bottom of the carb, and that's the main reason I got it. It only costs 11.49 too. Just thought I'd let you fellow carb workers in on the info.
