Ratlover, you are correct.
I knew that bumping back the timing would help, but until I got the 5 gas hooked up, I was just peeing in the wind.
Today, I got access to the analyzer. Found one very small intake leak on #2 cyl. intake runner. We were able to tweek the mixture some to compensate for that until we can fix it. Infared thermometer showed that cyl running 55 degrees cooler on the exhaust too.
Then we slowly bumped the timing back 2 degrees at a time and slowly the HC dropped. The max limit is 350 in gear, we finally stopped when it hit 276 and held steady. CO was kept right at 1% at idle. Tomorrow I'm off for one more official test. It idles fine, but is a total mutt off the line. Don't want to drive it any more than necessary like this so I kept it here again tonight and let my son take my '86 home. Hope I get it back!
