With a fresh engine, piston rings definitely are not sealing. You have oil intrusion into the combustion chamber. Furthermore, there may be assembly lube from the top end (cylinder heads) that are working their way into the combustion process. It takes time for things to stabilize. Clean the plugs and reinstall them. If you repeatedly get that black coating on the ceramic, then your carb is just running rich.
