1979 dodge mobile traveler 360cl wont pass emissions

Hi guys, I have a 1979 dodge mobile traveler with a 360cl engine, and i cant get it to pass emissions. The CO2 level is the issue.

I have changed the oil and the spark plugs and things improved but it still fails on co2.

any ideas on what to try next?
