Hi new here but have gotten a lot of good information from this place. I just got a 96 xp and am replacing grey fuel lines and rebuilding carbs using osd back to oem kit. It looks like they may have been gone through before. They had a silver spring in them. When I test it with that pop off psi was 29. When I put the black spring in that came with kit pop off psi was 35. They are both within spec. Which one should I use?
