After some suggestions that I reseal the gas-jet thread with some PTFE tape the flame has now become a concentrated blue tongue of flame. It turns out that my removal of the jet from the pipe had broken the seal and was allowing gas to escape through the screw thread and get sucked in where the air was supposed to go.
OK, I’ll admit that I preferred it when the thing was just putting out a veritable inferno, but the blue flame is probably more useful, albeit quite random at times.
I also had to clean the gas jet orifice, which is about 0.1mm diameter. I used a piece of thin enamelled copper wire to clean it.
The ebay listing this slightly dodgy burner came from is:-
