ENGINE
TUNE-UP
PROCEDURES
There is no scheduled interval for performing an
engine tune-up. As long as the engine performance is
satisfactory, no tune-up should be needed. Minor
adjustments in the valve and injector operating
mechanisms, governor, etc. should only be required
periodically to compensate for normal wear on parts.
