Welcome aboard, Silver Fox!
You obviously have a lot more experience with the engines than I do, but I should stress a couple of points just so you don't think that I'm totally nuts. There is no way in the world that I would ever consider making one of them airworthy. Note that I suggested it as an emergency motor for a possible boat, to be used sparingly. As for a weakened block, those things were pretty damned strong to start with. Weaker would still probably be acceptable. The alcohol fuel at low altitudes might not be that much of a problem since I've already scarfed the superchargers for use as air pumps in camp. Tweaking a carb is something that Hypatia or I can do in our sleep, unless the thing needs to be rejetted. (That would let me out, but she can probably do it.) You don't have that much compression to worry about. The one thing that totally weirds me out, maybe because I've never dealt with a radial engine, is your reference to 'compression bearings'. That is a totally new phrase to me. The only thing that I can possibly think of within my own experience that you might be talking about is a 'rod bearing'. If that's what you mean, then I believe that there are ways around that as long as you're willing to settle for severely limited performance.
Another thing that puzzles me, though, is your contention that the seals will be okay. The seals in a car engine are pretty much shot after sitting 10 years, and they generally aren't subject to 'jungle rot'. If you can elaborate upon this subject, I would much appreciate it.
Arildno, if you hadn't mentioned being gay in the other thread, I'd be having some real trouble trying to figure out what the hell your posts here were about.

As it is, huddling for warmth is okay, but don't try too hard to keep me away from the women.
Moonbear, I can sew, believe it or not. It's usually restricted to embroidering disgusting things on jackets, but I can put a sleeve back on if necessary. And I made my own wallet, which is starting to wear out now after 20 years. The most that I ever got out of a store-bought one was 3 1/2 years.
I'm going to post this now, because I don't want to lose it while I go back and check over some stuff. Back in a bit.
