Black spark plugs indicate that the fuel mixture is too rich in fuel. White spark plugs indicate that the fuel mixture does not have enough fuel. The proper color for spark plugs is tan.
Black spark plugs also indicate that oil is entering the combustion chamber and burning. If your lawnmower is 2 stroke, this is probably normal due to the gas/oil mix of fuel added to the tank.
If your lawnmower is 4 stroke, you need to adjust the carbs to reduce the amount of fuel in the fuel/air mix.
