Guest Anonymous Posted May 23, 2003 Share Posted May 23, 2003 I have a light stumble/misfire with my '73 tii. Recently converted to Pertronix/MSD. Noticeable at highways speeds and at idle. Hooked up a Heathkit CO Analyzer and it runs perfect except when there's a misfire (jumps to rich, then back to normal range). Should I be looking at timing? plugs? plug gap? Mess around with mixture screws? Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted May 23, 2003 Share Posted May 23, 2003 It's right in the mouth of the throttle body. Run your finger over it, it should be dry. If it's leaking, find a replacement. Quote Link to comment Share on other sites More sharing options...
