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
