CO is carbon monoxide (one part carbon, one part oxygen). Depending on what year the car was manufactured the emissions were lowered by adding an A.I.R. (air injection reactor) and later adding a catalytic converter. The A.I.R. simply injects fresh air into the exhaust manifolds to aid the combustion of unburned fuel and dilutes the exhaust gases. The converter uses precious metals as a catalyst to help lower the amount of unburned fuel in the exhaust gases. If these systems have been eliminated the car probably won't meet the standards set for the year of prduction. You can lean out the fuel mixture if the car is carburetted when you have to get it checked and then change it back afterwards. The car will run terrible when leaned out and the exhaust fumes will burn your eyes but you should be able to limp it in to the testing station. Some places here in the U.S. won't even check it without an A.I.R. and a catalytic converter installed. Check your local laws and build the car accordingly. The only other option is to race it at the track on the weekends. Good luck.
