So it has got the EB weak needle fitted and is still running rich. A quandary indeed.
Indeed. Now that I've centered the needle I'll put the carb on tonight and see how it runs. Float need was a long way out from the 3mm too so could have been both acting to flood slightly

No, wasn't loose, I only noticed it on the bench after I took the jet out and it was sitting in a place that meant it must have came from inside the carb rather than to the jet (given its top hatted nature)
In any case, cleaned the sparks, reattached everything and it seems to be running leaner with no soot pouring out when bipping the throttle. I've got the seats out to sand and paint the floor so will only know after a decent drive to check the colour!
Thanks all, will report back if any further developments!

If I had to take a wild guess, that top hat collar must have been slid onto the jet before it was last installed, and when you took the jet out it fell off again.
That would explain the rich running, it would be just as if the choke was partially out all the time because the jet would never be able to return to its normal position.
Just a thought.
