 Actually I broke the engine in per book.  And I ran the engine with mineral
 oil and high power settings for 60 or 70 hours on advice of the mechanic
 even though chances of rings seating any better were slim.  Don't know if
 rings are the problems in mine - bore scope was always good in about two or
 three exams by the mechanic according to him anyway.
