I put a Weber 32/36 on my 235 - I'm running Fenton headers, HEI ignition, everything else is pretty stock. Had engine rebuilt 15,000 miles ago.
The standard 140/140 jets left me way too rich, I swapped for 135/155. (thanks Rich!!!)
Still too rich, I put a 130 in primary side. Not much difference. With idle screw not touching the linkage, and idle mix screw adjusted for good running, (around 1 turn out) - I'm still running more RPMs than I should....
Does a 120 or 125 primary jet sound right to you with Weber experience?
