Refer to Safety Precautions on page 25.
Excessive valve clearance will cause noise and
eventual engine damage. Little or no clearance
will prevent the valve from closing and cause
valve damage and power loss. Check the valve
clearance when the engine is cold at the intervals
specified in the Maintenance Schedule.
The checking or adjusting of the clearance should
be performed while the engine is cold.
The clearance will change as engine temperature
rises.
