Ok so I did a rebuild on the Holley 1945. This was a remanufactured I got a few weeks ago, figured I rebuild it myself. Glad I did too. I also put a size 62 jet in. The jet in there was slightly bigger maybe a 64-65? The only number on it was 298. And it looked old, so they didn't put a new jet in. I have no idea what a 298 is. Any ideas?
