you probably have an air leak into the fuel system. If you've replace the 10um Yanmar filter, then check the housing and make sure you replace the O-ring with new. Check the Primary filter for leak as well. Twice I've same problem as yours, lots of black smoke & unburnt fuel. Traced to leaky fuel filter assembly (leaks air in). How that cause black smoke? don't know, go figure. Good luck.
