If it were mine --
I'd get it running sweet first, then worry about smogging it -
Oversmogged? I like that.
BACK TO BASICS!
You connected the line to the air cleaner - then plugged it? Why? Make sure it's not leaking. Better yet, plug it somewhere else, not at the air cleaner.
That line is supposed to provide oxygen to the cat so it can burn the unburned fuel. The cat may be plugged by now - coked up - but don't worry about that yet!
First - get the initial timing set - set it to 8 degrees.
Then make sure the distributor vacuum is coming from PORTED vacuum, not manifold. Find the PORTED vacuum source - connect it direct - no solenoids or other switches.
PORTED has very little or no vacuum at idle, then slowly increases as the R's are increased. MANIFOLD vacuum is strong at idle - that's the wrong one.
See how it runs now - bet it's better,
Next - do a search here for "propane trick" - read it ALL! Make the device, use it to make sure there are no vacuum leaks - manifold, carb base, brake booster - pinch off the auto trans vacuum line too.
Fix any leaks.
Now test it for mixture - per instructions. Set the idle mixture screws.
Now you have a starting point.
Until you've got the basics set correctly, using prayer beads, praying to the east, using the wailing wall, killing a sheep at midnight, doing nutter butter bypass, swaping to FI, etc will NOT help at this point in time.
Once you have all that in order, let us know how it's doing.
Meanwhile - check your local smog laws - best way - go to a local smog station and ask them what the requirements are - leave the Jeep at home till you know what you'll need to do (avoids complications,) just describe it to them. Many of those guys will bend over backwards to help you.
