Those not familiar with this engine, Bogs has written a book to help beginners build an engine. It is a wealth of information. I am not sure where it is hosted now, I am sure if you ask, he will direct you to it. Download it and read it. Even if you don't plan to build it... at least read it.
Hm, sadly I don't see any of the photos in Part 10 and later, only a couple of YouTube videos, and it doesn't look like they made it through your transfer.
