Default Engine Making Metal (Was: Nasa Icing courses)
Running the engine too slow at startup. Apparently, the cams in some
engines get lubrication mainly from the oil splashing around inside the
case. In some engines, 1000 RPM may not be sufficient for full
lubrication after startup. My A&P suggested 1100 - 1200 RPM.

Isn't that a stitch? Your A&P says 1000 RPM is too *slow* for proper
lubrication. Jim Macklin (and many others) says it may be too *fast* to
run your engine before proper lubrication has occurred. Who is right?

And my A&P says 1000 RPM or slower, primarily to save your prop on loose
rocks but also to ensure long engine life.

Argh. Wouldn't you think there would be SOME science to this?
