Evanman, most of your worries are going to be confined between the slow, main jets, and needle. About the only other things that can be changed on these carbs are the starter jets (choke), and altering the cut-away to enrichen the throttle valve. Sudco and Carb parts warehouse (carbparts.com) both have pretty good documentation on CRS carbs that you can print out, that will help you tune on these suckers. It really isn't that bad. If you find the exploded diagrams, you can get an idea of where everything fits.
