Tell us more, what air filters do you carry?
Have you checked the choke?

Thanks for the link Murdoc lots of good info on here, I'm running a standard air filter. I'll read through all this and try again. I'm not going to give up 🤣🤣

Don't give up, the solution is out there and the results are so worthwhile

At risk of covering checks already made, it doesn't appear to be an "adjustment" issue as there's no response to turning the air screws.

With size 40 idle jets this should be happening and clearly it's not. That's the issue, seems that idle jets or circuit is impaired (that's fairly normal if left for years etc) making any refinement redundant until you've got flow going.

In effect the elevated idle is having air that doesn't get paired with any fuel to give correct running when you shut the throttle. If it just gets enough revs going it will start to gradually draw through the main jet supply just sufficient to keep it running lean at those revs.
If the idle jet delivered fuel competently it wouldn't rise and also give you a response to air screw too.

Thanks everyone for all your support and advice.  I think there going to have to come off again and more time in the ultrasonic bath 🙄🙄 I think it's definitely down to blocked pilot ways... the saga continues  🤣🤣
