Re: emissions time!
Drop back your timing a bit, set your idle mix a bit lean, change the oil, and put some guaranteed to pass additive in the tank. Just don't take it too lean or you NOX will go high.
If you don't pass by adjusting it on your own, then take it to a shop that works on older stuff and let them adjust it, they know the tricks and do that stuff pretty often. A friend of mine in Tucson went that route and had no problems passing his 72.
