 Gary,
 As for  "running the engine at full power for at least a minute".
 I read in one of the EAA books a recommendation to tie the plane down and do
full power tests before first flight.
 I did this once when troubleshooting something else.  Watch temps - the test
will last long enough for a turn around the pattern.
 I didn't trust the wing tie down points and tied to the main gear.

  The best method is undoubtedly to make sure ahead of time that the engine
will run for at least a minute at full power - but how do you do that?  That
also has some uncertainty.
