Re: Carb Adjustment Question

The soot inside the carburetor is a sign of retarded ignition timing. Retarded timing will cause exhaust gas reversion into the intake manifold and up into the carburetor. It will also cause poor idle quality.

Try advancing the distributor a couple of degrees and see if it fixes your idle issue.
