how to change spark plugs
Clean away any dirt and debris from the spark plug hole. This can be wiped away, but blowing it off with compressed air works even better. Remove the plug with a socket or ratchet wrench. Make sure you have the right size for your plugs, usually a 13/16 inch or 5/8 inch wrench. And, you may need an extension, too. Turn the plug counter-clockwise to remove it. Put the new spark plug in.
