I fitted a Smiths water temp/oil pressure combination gauge to my steed and I am observing higher running temps on the freeway than in the city.
No blown head gasket, pure water in the rad (yes I know but I chose to do this, will add water wetter for anti rust later today), timing seems okay.
Outside temp hovering around 100 degrees, indicated in city around 190 but out on freeway it indicates 210.
I have also been fiddling with the carb adjustment and I think I have it right (no more fouling of the plugs) but upon shutdown it diesels on.
Thanks.
