I've had to deal with a few hurdles in registering my car here in California. One of which is smog, of course. I just barely failed smog the last time around, with excess hydrocarbons at 25 mph. A couple of people have told me to lean out the mixture, but i've never worked on a carb before. So my question is: How do I lean out the miture on a Rochester 2bbl carb and Is this even the proper course of action? It does smell strongly of gasoline...
