That is called dieseling. It is caused by carbon buildup in the cylinder head or plugs that create hot spots which ignite the fuel rather than the spark plugs.

Happens on carb engines because after ignition is turned off the cylinders draw fuel and air as long as the motor is still rotating. In a fuel injected motor the fuel is stopped when ignition is turned off.

Solution is to use some decarbonization product to remove the carbon.
