while rejetting my edelbrock carburetor i discovered the replacement needles and jets that come with the calibration kit are marked with a stamped number that is so small it is practically impossible to read even with a magnifier glass. i started thinking about all the "CSI" episodes i watched and put my brain in forensic science mode, at which time i grabbed a Sharpie and painted over the numbers then wiped off the excess ink from the needle. I was now able to read the highly contrasted numbers stamped on the needles and jets. CSI would be proud...........
