Winter Operation

[TraumaOne]

I live in Michigan, it gets very cold up here in the Winter. When I bought my Super A the guy I bought it from gave me a type of heavy vinyl sash to hang on the sides of hood when I'm out working in the cold. He explained to me that the Carb will "freeze up" if I don't use the sash to retain some of the engine heat.

Thoughts on this? I have seen a few pictures of others doing it so I'm curious how common this is?

Thanks,

Running 2 Cubs and a 130 for many years way north of your location. Never had to do anything like that. Sometimes pushing snow for many hours. No problems freezing up ever.

I'm also in Michigan. When it is super cold I do remove the grille, install a piece of cardboard that covers about half the radiator, and reinstall the grille. The only thing I worry about freezing up in the operator.

When it's cold and there is moisture in the air, snow or just moisture, ice will accumulate on the carburetor. Usually doesn't hurt anything.

Central Iowa, we used what we called heat housers on the tractors to provide some engine warmth for the operator.

And an edit: We also covered part of the radiator.

Yea, I could see that. His explanation seemed really strange to me, maybe it's possible he was using old fuel? I'll probably roll the dice this winter and just see how it goes without it.

I'm guessing that his water separator (fuel bowl) was full of water and not functioning.
The fuel and water must be able to separate. (The water gets a bit hard in the cold weather) The air source comes from the air cleaner, so it shouldn't be sucking any snow into the carb. I have seen frost grow on the outside of the carburetor while pushing snow, but that isn't inside the carb so I don't know what that would hurt.
Mostly, the side curtains help the engine warm up to operating temperature. Its not a bad idea to use them, but I don't think it is a necessity.
