So I'm a bit reluctant to mess with the throttle idle screw, as we put the idle screw next to the metering head back to where it was post broken connectors on the AAV and she's running like a dream albiet a tiny bit rich still. A friend is going to look at setting up the timing on Friday to ensure it's tuned properly.
I've still got to find an air pipe that has nearly chaffed through on the AAV but she'll last for now.
The car is not hunting at all now.
I think I can close this rather long thread off.
Massive thanks from the boy and me to all you guys that helped get us back on the road.
