Anyone have baseline jetting specs for a front mount four tube header? Started as CPR std kit for carbureted 03 rx-1 and has 2.250" down pipe and open exhaust. I am looking for main, pilot, needle clip, and fuel pressure specs if possible. Thank you in advance...

I built my own 4 tube header and had to jet up from a 130 to 145 where I'm still a bit lean. I'm going to 147.5 before I run it again. I have 17.5 pilots and the needles are in the middle but I have the springs cut down a couple of coils. The fuel pressure is set at 4.5 pounds. Hope this helps. Ken....
