Re: Only 1 spark plug is black??...HELP
I would try a different carb if possible -- preferably one that's 100% ok.
Otherwise, yes the dripping out the squirters is telling you something. Too much fuel level? Vapor pressure (shouldn't be a problem while running). Carb is not correctly assembled (check valve installed in squirter?)
I would take the carb off hot and look in the manifold after a good run. Is there liquid all around the carb baseplate and in the manifold? There should not be.
