ORIGINAL: Sport_Pilot

Some engine manufacturers (including OS engines) have now updated their manuals with a procedure which looks similar to the one at the beginning of this thread.
I have reviewed several of the newer models for OS, they are still recommending breakin at a four stroke for there ABN engines.

The procedure from OS I was referring to, is [link=http://osengines.com/faq/product-faq.html#q2]this one[/link].
The manuals are still written by not-so-enlightened PR people...
