I still like my Thermoquads, but....

Don't forget to back off the timing too if you have it advanced. That will help it pass.
even timing is monitored in CA, if its not within 1 of EPA sticker timing, it will fail and test only stations wont take the 10 seconds to back the distributor off to proceed as its illegal. If NOx is high, its EGR related, if the HC is up, its combustion related. Methanol (HEET) in the tank helps with HC levels. We suck........I tell you Rob, its the most unfriendly classic car state in the union with their SMOG laws, yet there are thousands of 2 stroke STIHL leaf blowers in use every day here and you can smell them 50 yards away as they blow their nasty 2-stroke smoke. But trying to get that segment of the workforce to clean it up with newer expensive SMOG regulated equipment somehow "disproportionally affect a certain class of workers"...I though we were a classless society?
