I definately am convinced now that it's an electrical problem. I was coming back to work from lunch today and the temperature was reading high and out of frustration I gave the instrument cluster a whack (think old school b&w TV styles) and the temperature went back down to where it should be.

Does anyone know where I can buy the original wiring and plugs for the carburetor/choke/temperature sensor area ?

Thanks again,

AARON.
