Bob What the manual means is to break it in a rich backed off from peak in a two stoke condition not in a blubery rich four cycle condition and to do it at full throttle. Never break in any ABC, ABN in a blubbery rich condition or you will end up with second rate or worse engine. Those initial thermal cycles are absolutely critical to the life of an ABC/ABN engine Run it at the proper temperature or ruin it.
