Tulip (Plymouth Voyager) 2.2L carb E-test fail

[Wizard]

Plymouth Voyager 1987 carbed 2.2 (early year).

Tulip was taken in for E-test, drove 25 minutes to get engine good and hot, past few days I drove total of about 58KM for past few days.

Idle:

HC 232 (limit 300) pass
CO 2.16 (limit 1.5) fail
NOX n/a
RPM 888 valid
Dilution 12.15 valid

40KM/H:

HC 101 (limit 105) pass
CO 1.06 (limit 0.75) fail
NOX 1375 (limit 1192) fail
RPM 1979 valid
Dilution 12.33 valid

Carb is 5220, 2.2L, rebuilt 2 years ago.
Air pump is working
Coolant is good, new thermostat.
Oil still fresh and amber-clear.
EGR is working and new.
Catalyst converter NOT replaced YET.
PCV replaced and freely breathing.
Compression ratio I took in 2004 was around 165 for all cylinders, if I crank too many turns, can pump up to 180 PSI.
Head is not "correct" for carb (using fastburn head 782 in Tulip's) and dated 1989, I did not replace head BTW. The 2.2 carb uses bathtub head (287).

History: Carb was ruined and messed with to run rich because of manifolds leaking. All fixed prior to E-test.

Note: note the PCV system I installed, note the hose from aircleaner to "another PCV" is hollowed out and using it as elbow nipple. The correct PCV is black one on left feeding into manifold vacuum.

How's your air filter? Also, I'd look into replacing the cat as well as checking the timing. But that's not "too" bad for a carb'd car. Better than my Rampage did! lol

Recent filter, replaced this last year remember tulip was run very intermittently and timed the ingition to 12 BTC as specified on the emissions sticker in 2004.

I could ask the mechanic to check the timing just in case.

Wizard, get the cat replaced. it'll get rid of most of your CO and NOx.

you're from peterborough right?? That's really too bad, I know an etest guy here in London who was able to get my Omni to pass and it passed with FLYING COLOURS. so well in fact, that I'm starting to think that he tried a couple of times, got fed up, and put another car on the machine with my vin....
