A properly tuned engine produces considerable carbon monoxide. Internal combustion engines are at their best "a bit rich". A properly tuned engine connected to a hot, clean, hi-cap catalytic converter (with suitable air injection into the exhaust upstream...) should produce no carbon monoxide. Even brand-new cars produce tremendous amounts of CO and CH for that first minute or two after each start... once the cat "lights off" CH and CO drop to very low levels. That is my understanding ... from like Popular Mechanics and stuff; I am not a combustion guy. (Except on weekends.)
