The origonal one - Newcastle upon Tyne, in the north of England that is.

I'd fit a thermostatic one, surely that would give the best of both worlds.
My thinking is that a lot of the cooling that the pistons get must come
from the oil that's splashing about in the crankcase rather than the water
jacket which has only indirect contact.

The plugs are the usual light brown sort of colour, and don't show any
signs of overheating.

I not sure exactly what the advance is, but I normally set it on the road
by finding the point at which detonation occurs under low rev/high torque
conditions and then backing off a few degrees.

The water temperature is normally fine, I never get any overheating
problems

Andy & Tony,
Thanks for your replies, it looks like I need to look at
the mixture, although it's always seemed to be OK it's probably better to
err on the side of caution and run it a tad richer.
