Thank you. Never perfectly but certainly not as bad as is it now. It had however started surging at idle and it was pronounced enough for me to feel that I'd better have a crack at the carb. It would never idle much below 800 but I have previously run a vacuum test on it and it was stable and didn't show any problems but i didn't note down the readings.

There were a few things I noticed while working on the carb. The return spring on the choke shaft was not attached so the choke could flop around quite a bit. The accelerator pump linkage was extremely loose with a lot of play in it. (it certainly used to stumble on acceleration from idle). Idle was not being set by the idle screw as there was a significant gap between the end of this and the throttle mechanism. The gaskets typically crumbled as I removed the carb. I'm not sure if any of this is relevant but I appreciate the support and guidance.
