Alright old guys( Not a bad thing, lol) you seem to know the most on the carb tricks. Trying to learn some of the finer points of carb tuning. Say my eddy performer is running a little rich or lean, and its more than the tuning screws will fix. what am I going to want to look at when I tear the carb down. I know jet sizes and other parts I have read about, and know what most do, but dont know say what sizes I would want to use. So could I by any chance get a bit of a crash course to start me on my way. Thanks
