When you're billowing black smoke you're actually starving the mixture of air and overdumping massive quantities of fuel in the chamber and it's combusting only a portion of it in the chamber, sending the rest out to combine with the air in the exhaust pipe which makes the massive black clouds. You really have to have the fuel turned up to "roll coal"
I could GET that effect by wrapping a plastic bag over my air filter
