Update:

I re-torqued the head and the exhaust/intake manifolds (not so fun re-torquing the manifolds!). Observations:

1) Exhaust leak seems to be fixed. But one of the manifold nuts, the one that's right next to the carburetor close to the firewall, wasn't very tight. That is one I can only get a wrench on, so it's very hard to get tight. I cranked down on it as hard as I could, but I thought I did that earlier. Bears continued checking.

2) The head definitely needed to be re-torqued. So it was good I did that.

3) I figured out that I had way too much oil in the oil bath air cleaner, which seems to have contributed to the excessive blowby I observed earlier. I drained the oil bath air cleaner (haven't refilled it yet) and put it back on, and the blowby seems greatly reduced.

4) Looking at the exhaust now, I don't see any signs of burning oil (though this is the first time I checked), so that's a good sign. Exhaust looks really clean, transparent.

Hope to post some pictures soon.
