Is the choke opening all the way? Sooty plugs make me think of rich running.
Try this: After idling for awhile, while still in neutral, rev the engine up a bit then go back to idle and shift into gear and try increasing RPMs. The revving will "unload" the excess fuel from the cylinders if the engine is idling rich.
