Well, I have never heard of that; and I have been a certified mechanic for 18 years. I know that you should run the engine between 2000 and 2500 for about 20 mins or so varying the rpm a little as you go. I don't think that starting a brand new engine WOT is a very good idea. The most important thing to remember is to not allow the engine to idle. You can start/stop if you like; but no extended idling. Joe 61-G [Non-text portions of this message have been removed]
