Just pulled the carb.
My memory was not good!.

178 main
40 pilot
N1EF 2nd from top
#7 slide
Air screw 2 turns

Plug is currently black but I was just off idle for 300m with a half full 20l Jerry can on my lap before it was shut off.

Idles perfect and i think it pulls well from low to high.
bit smokey at 50:1 at idle
maybe loads up if idling for any length of time but couple blips and it's cleared.

Edit
Checked float before and after
Was in around 6.5mm to the highest point
Set it to 8mm reducing amount of fuel in bowl.
Does that look correct?
