I cannot belive I have every size allen wrench, BESIDES the one I need. I have the size before it, and after it. Im going to pick it up tomorrow so I can get into the float bowl on the carb and change my jets. I just need to know what size I need for the little allen screws on the carb (the ones around the corners of the float bowl, and top of carb, and the one on the clamp). Thanks, Mike.
