Important: 
   •  Before you remove the valve locks, rotate the engine so that the  piston
in the cylinder you are working on is at  top dead center (TDC). This
     will eliminate the possibility of the valve accidentally falling inside    the
  cylinder.    •  Break the spark plug loose, and clean any dirt and debris from  the spark
plug recess area before removing.
