I frickin'
KNEW I was doing something stoopid - I just figured out what my malfunction was.
The black gasket goes AROUND THE OUTSIDE of the alloy ring. Uh, yeh, that looks much easier...
Just took me 10 minutes, outside, by torchlight. Had to stretch the gasket twice, one thump with the palm and it seated, nip up the grub screws.
