5-5 BREAK-IN OPERATION

An engine that has been completely overhauled by being fitted with a new piston, rings, valves and
connecting rod should be thoroughly RUN-IN before being put back into service. Good bearing surfaces and
running clearances between the various parts can only be established by operating the engine under
reduced speed and loads for a short period of time.
While the engine is being tested, check for oil leaks.
Make final carburetor adjustment and regulate the engine operating speed.
