First test:

Test RPM %CO2 %02 HC PPM C0 %
Idle 674 12.0 3.6 300 max 651 measured 3.0 max .24 measured
2500 2585 13.76 1.3 350 max 36 measured 3.5 max .07 measured

What the heck do I know. It looked pretty good besides the idle HC numbers. After this test, I replaced the vacuum line from the base of the carb to the vacuum advance can. I removed and plugged the vacuum line to the dead cruise control. I replaced the carb base gasket and checked for additional leaks with a can of carb cleaner around the intake ports, all vacuum sources too. I bumped the idle slightly.NO EGR, NO cats, NO thermo air cleaner, NO spark retard, stock dual exhaust.
The second test, the truck WAS a little cooler. It was before 9:00 AM.

Test RPM % C02 %02 HC PPM CO2%
IDLE 862 11.36 4.4 300 max 1003 measured 3.00 max .16 measured
2500 2478 13.48 2.1 350 max 55 measured 3.50 max .05 measured

Maybe someone can decipher these numbers! Please excuse how close all the numbers appear to be jammed together. I tried to space them apart further but they cram back together! The reason I asked about catalytic converters is that I could weld a pair of high flow cats in CHEAPER than rebuilding or replacing this carburetor.

I don't mean to dump on smog techs, its just that it costs money EACH time they test the thing, and I figured that they were in a better position to diagnose a problem.
