I didn't catch this whole thread but it looks like a fun project.
I'm curious how the final cost compares to buying a finished unit.
A friend of mine bought a china-diesel genset a year or so ago
and it was pretty much a turn-key operation. I don't remember the
price but I think it was quite reasonable. He uses it regularly
and it seems to be running well.

Another thing I am curious about is how long the love-joy
coupling lasts. I think you have a 2 cylinder diesel and I
suspect the coupling will be subjected to a fair amount of
pounding.
