Robin EC12 - Break-in Operation

6-5 BREAK-IN OPERATION
An engine that has been completely overhauled by being fitted with a new piston, rings and crankshaft
assembly
should be thoroughly BREAK-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.
