'84 pickup wont pass emissions
I'm at a loss at this point. It's a 22R carburated. Recent work on the truck includes:
new exhaust & cat
plugs, cap, rotor
PCV
oil & air filters (oil change, duh)
The truck seems to be running as smooth as ever, but the CO reading is high. Are there any tricks to get a car to pass the test, even if the fix is just temporary? I've heard alcohol in the gas, but not sure what kind of alcohol or if this is even a good idea. Anything else?
Thanks in advance! I just want to get this thing back on the trails

Thanks, any other suggestions?
I'd like to get any info I can before I take it in to get tested again. I've had to pay for the test three times now

This is more of a last resort. I've done this in a parking lot near the inspection just before taking it in. Find the air adjustment on your carb. Lean it out while listening and watching a vacuum gage if you got one. Lean means it runs hotter, so don't leave it like this after inspection or you'll burn valves. good luck. let us know your results.
