This must be the ultimate "good news, bad news" message. I'm really sorry to hear about the problem, but at least the mystery is solved. Rust has been a problem for a few people, and Finn recently posted a message about the rust he found in his junk yard engine. I also had similar rust in my "new" engine that came from the RX-7 Specialties generator engine batch. The problem is that someone ran the engine, then drained the coolant by disconnecting the hoses. Obviously, this doesn't drain the lower half of the engine. The answer is to use the block drain at the bottom of the center housing on the plug side. If anyone has an engine sitting around in storage, I'd recommend opening that drain to see what comes out.
