I guess I will have to answer my own posting as I just past the emissions test and I hope I can impart some useful information to others searching this web sight that has been very helpful to me.

I used the % function of the volt ohm meter across the the freqency valve and adjusted lean/rich so it was running about 62%, (or 38% if you reverse the polarity) when it passed emissions. Timing was set at 10 BTDC.

When I was initially trying to set the % there was a wide range in the readings, but it seems they stablied after checking connections to the oil temp. sensor, O2 sensor, and water sensor. By the way the oil and water temperature sensors are normally closed when cold and open switches when at engine warm temperatures.

Even though I passed the emissions, the intermitent high idle is still lurking and fortunanlly did not materialize during the idle/2500RPM emissions test. Maybe it is curred, but I am suspect it is the idle control unit (not valve) or sensors feeding it.
