That's Zeeeerooo HC and CO at idle and 2500 rpm and
very minimal HC at both speeds.  I trusted that the
engine that I used had been well cared for and
invested the money in a factory rebuilt carburetor and
it seemed to have paid off.  The above results are
after a first test where the car failed because the
EGR valve was wrong.  I had enlisted the help of a
very knowledgeable list member to help me spec out the
EGR valve (Thanks John, I mean it.) but we were both
wrong about the type of valve that was required. Also
the bypass valve for the air pump was defective and I
replaced it with a functional valve from a Pacer in my
garage.

It just shows that even 1970s cars can perform well on
emissions tests if they are set up correctly.  You do
not have to disable the primitive emissions control
devices installed by the factory.
