ENGINE COMPRESSION
Ensure battery is fully charged. Check engine compression with engine at normal operating temperature at normal cranking speed, all spark plugs removed and throttle wide open.
VALVE CLEARANCE
Note. All models are equipped with hydraulic lash adjusters. No adjustments are required.
