You will need a compression tester. Once you get one, warm up the engine, then immediately remove all 8 spark plugs, and wedge the throttle wide open. Disconnect the ignition coil. Start at whichever cylinder you want to, and attach the compression tester. Crank the engine over for 5 consecutive rotations. Go read the gauge. That is your dry compression for that cylinder. WRITE IT DOWN! Then go to the next cylinder and do the exact same thing. WRITE IT DOWN! When you have done this to all 8 cylinders, you have finished the dry test. Next you need to do it wet. For that, you will need a quart of oil, and either a squirt can or a small funnel and a piece of fuel line. You are going to do the exact same thing you did for the dry test, except just before you do each cylinder, squirt or pour the equivalent of three soup spoons full of oil into that cylinder through the spark plug hole. After you've put oil in one cylinder and attached the tester, crank it over 5 times and read the gauge. WRITE IT DOWN! Do this for all 8 cylinders, and post the results here. This test will tell us a great deal about the condition of your engine.

Take care
