The OS 46AX engine is decribed as an ABL engine (advanced bimetric liner) and I could not find where it said to break in the OS 46AX any different that what the instruction manual says.

The consensus of most experts is that they should be broken in rich, but not sloppy rich. Here's a thread that has lengthy information on breaking in this kind of engine:
