gday glen,
to check the compression of a cylinder you need a pressure guage, looks like the ones you check tire pressures with. It has a threaded end that you thread in the place of the spark plug.
Make sure you disconnect all spark plug leads, so the engine won't start when you crank it over <img src='http://www.squidfish.net/forums/public/style_emoticons/<#EMO_DIR#>/laugh.gif' class='bbc_emoticon' alt='
' />: , and you take out one spark plug at a time and thread the pressure guage in its place. you then crank the engine until you get a stable pressure reading on the guage and note it down. do this to all cylinders and you will know how good the engine is compression wise. <img src='http://www.squidfish.net/forums/public/style_emoticons/<#EMO_DIR#>/wink.gif' class='bbc_emoticon' alt=':lol' />
Not hard to do but it will give you an indication on the condition of the engine.
