holley sniffer test
Im currently running a holley 600 carb with the vacuum secondars on my 91 camaro 350 with a california emisions legal cam. I was wondering if I prevented the back barells from getting fuel, and lean the front barrels, could I possibly pass the emmisions test, I have a brand new cat, and full exhaust with no leakes. Or if anybody else knows anything else I can do to help me pass, thanks I need more time so I can put a tpi kit on my car

You should be able to pass with ease. You might not even have to do anything to the carb...I'd give it 50/50 it'll pass as is.
If you really wanna be on the safe side..just open up a couple small vacuum leaks..like one or both of the small ports under the front of your carb. Then lower the idle speed to compensate and call it good.
Stop a block before the emissions place and do it...then stop a block after and fix it.

Yep, you can take your ergonomically designed, space age, computer controlled, 4 door, cup holding map lighted split double wishbone split fold down retractable cargo covered moon roof piece of transportation and keep it. For I have felt the thunder. And I know the difference!"

That's usually what I do along with reducing the timeing a little... watch for the glowing headers too! Visual is what kills me ![](https://www.thirdgen.org/messgboard/frown.gif)
