I managed to remove the plug and reanneal the copper washer, then smoothed it out with 600 grit sand paper on glass so it was super flat - still drips!
Off to the store and got their last two 22mm ID copper crush washers (900.4230) - yippie - installed one and it still drips.

The plug threads in and out easily so no issues there.
Should I try 2 crush washers?
Some sort of thread seal plus the crush washer?
Any thoughts or tricks I am missing here?
Thx
