Re: Sooty #7
There are two kinds of soot. Soot from running too rich, aka a leaking injector. And then there's soot from excess oil in the cylinder, which could be a ring, valve guide, gasket or porous head issue. Highest probability is the injector. Resistance, as was pointed out, is irrelevant when leaking.
Do you have a photo of the plug and the soot?
