'78 Spider FAILS the NC Emissions test!



Following minor tune-up.  Just replaced dual point 
w/single and rotor/cap/condensor.  Spica cold start 
solenoid adjusted.  Thermostatic actuator within specs.  
Spica pump oil filter and fuel filter replaced.  New air 
filter.  Fresh oil change and filter.  93 Octane fuel.

Converter still installed.  Air pump was removed long 
ago by the P.O. but missed by the emissions inspector.  
Performed vigorous 'Italian tune-up' prior to emission 
test!

Here are the results:

HC     216(ppm)   Standard 350
CO     4.88%      Standard 3.50   BUST!
CO2    10.7%

Engine RPM at Reading 988 (max allowable 1100 RPM).  The 
car's tachometer indicates a 750 RPM idle but the test 
device showed over a 200 RPM error.

Any ideas to reduce the %CO?  The idle speed does not 
respond more than about 100 RPM to adjustments to the 
idle equalizer so I don't think there is enough 
adjustment to lower the % CO to less than 3.5%.

The mixture set too rich?  Car starts and run great 
regardless of temperature so I hate to mess with a good 
thing...

Thanks!

Jeff
