Emissions help

I agree I think its a bit ridiculous that its required for a car that old at all. The engines not in the best shape but it doesn't burn oil or leak. I do believe the cylinder rings are worn as my plugs have a bit of oil on them but It runs pretty strong and passed the driving portion but apparently idles rich. I've been looking around trying to figure out how to adjust the carb but dont think I can pull it off so I may have to take it somewhere. I plan on doing plugs and air filter myself and hoping that helps?
