Thanks, Graham, you are right.
I thought the fuel was coming out of the little hole on the top of the carburettor, but on looking again I can see it is flowing through that hole from the pool on the other side. As a test, I wrapped rags around the union and they quickly got soaked while the top of the carb remained dry.
I disassembled the union and got a very sticky bitumen like substance around my fingertips, which took ages to remove and took my fingerprints with it! I think the previous owner had had a go at sealing the joijnt. The bolt head is in a bad way so I have ordered a new union bolt from A7 Components plus a set of new fibre washers. I'll cross what's left of my fingers and hope that fixes it.
To tie up a loose end and answer my earlier question - Burlen's Zenith rebuild set does include the needle valve.
Thanks for the help.
