Funny thing, this carb oil business. I ran my B year round in Montana
and North Dakota without any such difficulty. I always have subscribed
to using the same oil in the carb as I put in the crankcase. I was
probably using at least a 5W-30 in those temps, but I can't remember for
sure. Yeah, it got a little stiff, but that made the "accellerator
pump" function work better until the engine got completely warm.
One concession I made to the extreme cold (we ALL did!) was to install
an electric block heater and plug the car in overnight. This served to
keep the coolant warm and may well have had a small affect upon the carb
damper oil.
The only time the car failed me in this extreme weather was when I
stupidly "high centered" the low-slug GT on an unplowed street. Took me
forever to dig that sucker out.....
