Thanks for this which is very interesting. Actually what I wrote was that I had changed the head gasket, however having just checked it must be a Ruby head as it has two bolts/nut holding down the water inlet pipe. I can see that the plugs are located exactly as you describe. Wii get some hotter plugs and see if that helps.
Also Stuart Giles suggested that the richness could be caused by excess fuel in the chamber. I have lowered the fuel 'thingy' by 40 thousandths (by adding another washer). Will see if this makes a difference. Engine is sounding sweet at tickover but seems to get lumpy at and above 2500 revs. Am thinking this might be a another issue.
Thanks for your help
