Engine Compression
- Check compression pressure with engine at normal operating temperature, all spark plugs removed, high tension cord from ignition coil.
- Disengage clutch (to lighten starting load on engine), and depress accelerator pedal to full throttle position. Crank engine at least 6 revolutions to determine engine compression.
