On two occasions I have found the jets I have purchased to be marked incorrectly. I bought 5 different sizes sometime ago and started jetting my NT carb for wide open throttle. Everything I tried produced no results or things got worse. I eventually bought a set of needle drills and used them to measure the jets. I was shocked to find that all five jets were the same size but had different sizes stamped in them. Just this weekend I took delivery on a Dellorto Type carb and it came with 15 different jets, sizes 61-75. I got my needle drills out and measured them and out of 15 there were only three different sizes. 71,72,and a 69. All the rest were the same size. I now solder the jets solid and drill them myself and this has made life a lot more predictable. I really like the Dollorto Type carb but that's a different thread.
