You're always going to get carbon in the exhaust pipe, so black is normal. Get it warmed up and see if it still has liquid in there, you should be able to tell right now, though, whether it's oil or condensate mixed with carbon. I've built a few engines and have never noticed oil in the exhaust pipe, broken-in or not. Oil leaking from other areas, but not in the pipe. Hope you ran the initial break-in procedure before taking the road.
