Thanks Bruce.

As a postscript to the crankshaft/bearing rework, I neglected to mention that one of the main reasons that I wanted to tighten up the bearing clearance was so that an oil film could be maintained as the crankshaft turns. With all that looseness, the oil just tends to run out of the bottom of the bearing very quickly. Now, when it's running, the oil cups remain full for an extended period.
