The plugs coming out should be light tan/gray in color. This is the tell that the spark plug is running at the right temperature and that the engine is in good shape.

Dark or a black wet or dry deposits indicate an rich condition, too cold a heat range of the spark plug, low compression, retarded timing or too large a plug gap.

Then there is a plug with deposits or melted electrodes. Let us know what yours look like when you change them.
