        Offhand, I'd say that your idea of "dirty" needs some revision.

        Here's a comparison of yours versus mine...at IDLE

        Malcom's carburetor       California spec '91 Carat
        equipped '91                tested 6/01
                                              MAX ALLOWED
        HC 228                    HC  0023    0120 (ppm)
        CO  2.23                  CO  0.03    1.00 (%)
        O2  2.03                  O2   0.6     --
        CO2 12.5                  CO2 14.3     --
        A/F 14.9                  A/F  - -
         RPM  914                  RPM  890


        Please NOTE the CALIFORNIA MAX ALLOWED values for HC and CO
        which your carb equipped engine hadily exceeds. The CA average
        test result for the same vehicle year are HC= 0.30 and CO= 0.10
