That evening with the car back together we ventured off to our friendly mechanic for him to start a program of getting the car to run properly

This time he cleaned up the throttle body as it was full of crap and also the idle valve





We also found another bodge, a suspicious nut being used on top of the fuel regulator. At least it’s the right thread



It certainly ran better after these tweaks but still more to do with quite a few evening visits I am guessing.
