- Black sooty deposits on the plugs is still a definite indication of a
- rich running car. You replaced the carb but was it adjusted or checked
- with a gas analyser? Are you sure the choke opens up completely? If not
- then check for power TO the choke. Also possiblity you clogged the
- catalytic converter, is power normal? Not too likely on this car but you
- might check the vapor cannister and controls also.....
