Black smoke is caused by too much fuel going into the engine. (often seen when running under load) If the engine smokes with little load and is worse at high RPM, it could be a plugged air filter. I have seen a Cat 3208 cat backfire and smoke as a result of a plugged air filter. The backfire only occured after the engine had reached operating temperature. I believe there was not enough air availiable to burn the fuel. This resulted in a loss of power, which opened the throttle even more. As a result, the unburned fuel was probably igniting prematurely on the next compression stroke causing the engine to run very poorly and backfire. After replacing fuel filters and checking for air leaks in the fuel supply with no success, replacing the air filter solved the problem.
