Re: motor runs rich plug are black soot
How do you know the carb's adjusted correctly? You have deactivated much of the smog equipment and are running heads that didn't come on the motor, so its not inconceivable that the carb doesn't need re-jetting and/or a different power valve. I'd step down two jet sizes, drive it for a while and the re-assess rich/lean conditions.
