First post though a member for a short while. Sorry to revive this post, but I have a1985 full frame off, 30 over 258, HEI, stock headers, glasspack, and a weber 38 sync. I spent hours reading the advice about the weber, opinions about the weber (I could only find 2
) and finally made the buy. The carb came and I followed the exhaustive setup and calibration procedures posted here and got it right the second time!! (ended up with 60 idle jets and non-standard timing at 10).
Short story is, this forum has all the info you need to make well informed decisions and successfully install and tune a 38 for a 258. I think this combo can't be beat IMHO. Thanks to everyone (I won't name names 'cause I can't remember all the great contributors) for helping me to meet my life-long goal of rebuilding an old CJ. I won't say the process was painless, but I'm not dead yet
