pumping air directly to cat

I think it's because I'm in the SFV, and it might go by address, not where you test? Yours may be AQMD - South Coast?

But it's an interesting observation. SUE DA BASTARDS!

Since this thread has sort of become the "show us your numbers" thread, I finally got the cruiser smog tested today and it passed. These engines can pass legit if everything is working correctly.

• Original block with 277680 on the odo
• Overhauled head 2 years ago (& manifold)
• Cleaned out, semi rebuild carb 3 years ago.
• Recurved dissy
• All smog equipment installed (and apparently working)
• Timing set on 7° timing mark (though tech wrote down 10° because he was too lazy to check the timing)
• Fresh mid grade Chevron 89 octane gasoline with no ethanol added
• 5 gallons of gasoline in the 48 gallon tank (which annoys the tech during the EVAP test)
• 31" tires. 3.70 gears.
• OEM cat

But frankly, if my engine didn't pass I would have been at a loss as to why. I had gone over every component very carefully prior to the test.
CA makes you earn it!

What's interesting is that @Spike Strip 's test shows the max allowed limit for NOx much lower (751) than my max allowable limit (1073) and we tested in the same county. I wonder what's up with that?

Nice work. Your CO is f'in low!

So I did as per dr. Jim prescribes. Vent abv. I went in and still failed. I was running fine on Nox and HC but CO was 3x the limit for boulder Colorado. After Jim’s treatment the pendulum swung the other way. Negligible CO and HC and nox was just over the limit. Went home and put a few caps of distilled water down the carb and reved her up to clean the prison heads. Retarded the timing to about 5 degrees btdc. Just skated by. Again. I now have until 2021 to move out of this draconian city....
