Thermoquad tuning to pass smog

I essentially got a good deal on it because the current owner just wanted it gone, I need it to pass to transfer the title and get tags....In California (even in a no-smog county) It has to pass smog to transfer the title. In California 1975 and older is smog exempt.

I played around a little with it yesterday it seems to have a vaccuum leak somewhere(cover it with your hand and it smooths out and raises RPM) I traced all the emissions lines and they all look good (not cracked or anything). I think it still might be a carburetor problem as it really seems to not run right no matter what I adjust.

I did the carb cleaner around intake manifold, carb base etc. and it all seems fine.

thanks for the information so far.
