Bruce, that is a gorgeous engine, and you did right by it. I can't believe how smooth it runs at low speed!
In a way, you remind me of me. I tend to agonize over the amount of play in crank bearings, rod bearings, valve linkage... and a part of me is always scolding, "Let it go, it runs fine...", and usually I listen.
A good example is the Carette engine on my bench now. I've already decided to make a new crankshaft and install bushings, but I keep thinking I might as well go ahead and make some sleeves for the loose connecting rod and valve linkage. Then I think, why? It won't make that much difference, and it's not like it's going to be run very much -- at least not like when it was new. It will spend most of its time on the shelf. And so the conflict rages on...

exactly! absolutely "everything" can be improved... but at what cost (in effort) to the minute difference it may make. This was an easy fix and something that will last for another 70 yrs. I hope.
