The procedure for testing compression is as follows:
1. Warm the motor to operating temperature.
2. Remove all spark plugs to make the motor easier to turn over and save the starter motor.
3. Wire the carburetor primary throttle blades wide open so the motor can breathe.
4. Disable the ignition system so that you will not cause a fire.
5. Turn the crank through at least 5 compression cycles on each cylinder. This procedure will top out the readings. Make sure you have enough battery to accomplish this.
