Next two hours:
Accelerate at full throttle onto plane,
then reduce engine speed to three-quar-
ter throttle (approximately 4000 r/min).
Vary engine speed occasionally. Run at
full throttle for one minute, then allow
about 10 minutes of operation at three-
quarter throttle or less to let the engine
cool.
Your new engine requires a period of break-
in to allow mating surfaces of moving parts to
wear in evenly. Correct break-in will help en-

life. NOTICE: Failure to follow the break-in
procedure could result in reduced engine
life or even severe engine damage.
