Peter.
Black smoke indicates that the fuel/air mixture is too rich.
Carburation varies greatly across the Briggs & Stratton engine range
so it's difficult to generalise about what to do. You need to check
the service info for your particular engine to find out how to clean
jets/adjust mixture. If you get BLUE smoke, that's burning oil caused
by engine wear.
