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.
