Quick Update:
Plug caps arrived and fitted - made no difference
Also received my infra red temp gun - fantastic little toy! and indeed £8
At idle from cold it seems after 5/10 minutes that the cylinders are about 160 degrees or so at header, apart from no4 which is around 200 degrees. I haven't had time to play with the mixture on 4 to see if it would bring it into line with the rest, but I also wonder at this stage whether a partially blocked idle jet would lean it out and cause the discrepancy.
Gives me something to play with on my week off anyway.
