Engine Compression

Check compression pressure with engine at normal operating temperature, all spark plugs removed and throttle valves wide open. Ensure battery is fully charged and starter is operating properly. Install remote starter in starter circuit. With ignition switch in the OFF position and using the remote starter, crank engine at least 5 engine revolutions per cylinder to determine engine compression. Compression readings are considered within specification if the lowest reading cylinder is within 75 percent of the highest reading.
