BOHICA29,

In time, you will develope your own routine for breaking-in a new engine. For now, follow your instructions very closely, and if I can offer some advice, don't be afraid to run your engines a tad on the rich side. Remember that a motor "unloads" in the air (which is why the manual recommends you not tune your engine to "peak" RPM's). Besides, a few extra paper towels to clean the oil residue from your plane at the end of the day is alot cheaper than having to replace motor bearings.

Treat your OS right, and it will last you for many years.
