downdraft weber rebuild

[snootcheez]

hello all, im new to this forum and z cars. im working on a 73 240z with the downdraft webers on it and the car runs rich..very rich. i need to rebuild the carbs and wondering which jets are the best for getting the most out if it. im thinking about maybe adding a little extra horsepower later on so a little rich right now would be ok! thanks! kris;)
