Black smoke is an indication of to much fuel or too rich a mixture,when flooring the excelerator you have a waste of unburned fuel,it is better to excelerate slower to give the engine a better chance to utilize the gas. you are burning off the carbon deposits inside the engone...flooring it is not a good idea nor is it good for the engine. The better way to clean the engine is to take it out for a 30 min drive at hi-way speeds.
