Yeah, it could be running rich if there is a black carbon buildup on the plugs. If the plugs are kind of oily and black then there is oil getting into the cylinders. The sparkplugs on a properly running engine should look greyish.

Oil is fouling the plugs probably. Leaking past the valves or piston rings.
