So throughout the repairs or tear down of the top end, did you ever really nail down what was causing this "rattling" ... was it valves floating with really weak springs or perhaps preignition due to an extreme amount of carbon build up and was that from too rich a fuel mixture or was it using excessive amounts of oil ? . Then the matter of the mystery air loss in two cylinders as you pressured them up. Just curious to find out what was really going on inside that engine.
