That is a sure sign that it is running way too rich. When it starts to run out of fuel it leans out, less fuel to air. That also makes sense since your plug is black. You will need to rejet your carb. You can either buy a different jet or solder and drill. Norm has all the details.
Design is easy, execution the hard part.
