Well, the 84GL finally passed smog.  What it all came down to was
increasing the RPM by about 100 (up to 990 at idle) and then a minor
adjustment of the AMF CO screw and it passed.  In checking past history,
whenever I go in and the RPM is at about mid range or below, it fails.
When it is near the top end, it passes.  Interesting.  I am still
looking for a really good way to adjust the AFM spring.  Will work on it
and report back if there is any breaking news.
