I purchased an 84 fJ60 from my Uncle in Montana a couple of years ago. We trailered the rig back to CO, and I finally have some space to work on it. So far, I have boiled the rusted gas tank and relined with red kote, changed plugs, wires and oil. This site has been amazing and provided endless information and resources. I’m thankful for everyone sharing their knowledge with us novices.
This weekend I removed the Weber 38dgas from the desmogged 2F for a rebuild. I have changed the idle, main and air jets based on a post from @Dizzy (elevation in Nixon MT is 2100’ vs 5280’ Denver). The rebuild kit I got has a 1.75mm needle valve, replacing the 2.50mm that was installed.
After doing some research, I found the original needle valve for Weber 38 is the 2.50mm. I have rebuilt the carb but haven’t installed it yet (waiting on a single gasket I was shorted in a kit). Should I put the 2.50mm valve back in?What will happen if I leave the 1.75mm installed?
Any feedback is much appreciated. Here are some pictures of the rig and the work completed. Thanks!
