I believe you are mistaken about that, Bob; the CO is (and was) measured in
percent.

FWIW, the state of CA applied the following standards to my 59 TR3A (back
when all cars had to be tested on transfer of ownership) :

Cruise HC 	400 ppm
Cruise CO 	6.5%
(note that "cruise" in this case was defined as a certain rpm with no load)
Idle	HC	1200 ppm
Idle 	CO	8.0%

BTW it passed easily, AFTER I richened the carbs back up.  First time I took
it in, the machine rejected it as being too clean !

Also worth noting, perhaps, that the emissions control devices are designed
to meet a much more rigorous standard than the simple tests done during a
"smog check".
