Next you will need to remove the old head gasket. This can be done with a sharp chisel by gently scrapping perpendicular to the cylinder block; the gasket will peel off. Light scratching can occur, be careful not to angle the chisel and leave any large marks.
Using your sandpaper rub down the block and the head to remove any light scratching and left over dirt. Using a circular motion helps maintain an even sanding job. If the head is warped you can tape some sanding paper to a piece of glass and rub the head against it in small circles. This will insure a perfectly flat head. You can colour the head in permanent marker and this will show where the high and low points are as you sand.
Once the surfaces are prepared you may install your head gasket and reassemble the lawn mower as shown in the video.
