interesting thread. Not clear if the burner was ever really sorted out. I found a comment on the web that suggested that the ceramic can burn out. There are ceramics about that will take higher temperatures but none I am aware of in this form.
I found a couple of bits of information
A cavalier view of the setting up of a burner but its short clear and to the point.

I suspect I would try fitting the end of the burner on the torch as supplied directly into a burner tube as at some gas setting it should provide the right mix.
And one design. I would double drill the hole to try and get the final size correct, just removing a touch with the 2nd one maybe by hand.
