My HS4 carb left a lovely small puddle of fuel on the bulkhead when I tried to start the car (unsuccessfully!).

I assume the fact that the carb leaked and that the car wouldn't start are related, but I've never heard of carbs leaking fuel in that place.

It is right under the adjusting nut, but the small pipe going from the float chamber to to the adjusting nut bit of the carb is also wet so probly the float chamber is leaking. At the top where fuel enters the float chamber there is absolutely no fuel and its completely dry!

I don't know if this has any relevance but the adjusting nut turns very freely, more so than my other HS4 carb!

So any ideas what it could be? I want to get the car started!

Sounds like its the seal on the pipe from the float chamber to the jet.

Its not unusual for the adjusting nuts to be tight or easy to turn. Unless the jet has actually siezed in the adjuster and when you have tried to turn it you have stressed the pipe.

To be honest I cant see a small leak from there stopping the engine from starting. Unless the float chamber has completly drained, take the top off the chamber and check for fuel.
