My '75 Royal Monaco Dodge 360 2V Holley 2245 used to ice up in humid weather around 40…no matter how well the heat stove and thermostat worked…what a pain…flood out every time unless you babysat the thing.
I think if it was a flashpoint problem, the engine would never have started in the first place rather than stalling out while running.
Unless he started it inside a heated shed and then went out into the cold.
They probably have extra low flashpoint gasoline formulas just for arctic use, you could probably fill the tank with liquid butane and use it like gasoline.
Long time lurker, first time caller. How does Antarctica enter into this? What did I miss? Isn’t it a desert anyway? Oh wait, never mind, I missed it. Sorry.
Latent heat of melting and of vaporization are significant amounts of energy (32 degree water as opposed to 32 degree ice. It takes alot of energy out of the carburetor body wehen the fuel vaporizes…vaporize enough and you’ll get the moidture to freeze at 80 degrees.
