Takes a while before SAE30 will start flowing well. Also takes a while before a carbureted engine will actually drive a transmission without stalling.
I usually run 0w-20 in the Focus in the winter. It flows instantly. It has EFI, so it starts instantly; no cranking for an hour while I pump a gas pedal and hope and pray it might start sometime this year. I usually wait until it idles below 2500RPM and I take off.

I've been born and raised close to the arctic circle. Every year the people there drove their cars in temperatures from -30 to -40 °C. Even carburetor cars didn't suffer from those problems. Carburetor will do just fine if it is in a good shape. Battery has to be also suitable for cold winter. I never would use SAE30 oil in cold temperatures. It just doesn't work in cold temperatures. Keep your car in a good condition, use modern synthetic oils and you will survive cold temperatures without any major problems.
Problems will happen if:
- battery has enough capacity only for a nice sunny summer day
- carb is worn out
- choke is not working
- ignition is weak
- oil is not suotable for cold temperatures
