i have seen a site with the schematic for an exhaust gas analyzer. i think your 75 exhaust could have a fitting for an O2 sensor. the analyzer displays mixture readings by LED's. looked buildable. my mechanic adjusted the pressure sensor (74) to get close. valve lash made the biggest difference in all things tried. idle still oscillates but runs very good! i've read pressure sensor has greatest affect on emissions controls/mixture controls.
