Are your carbs HS6s (side bowl) or HIF6s (bottom bowl)?
If you unhook a fuel line before you crank is there pressure there?
Are your plugs clean and your ignition system good?
The only problem I have had at low temps was that sometimes it cranked
too slowly.
Better check to make sure that your chokes are working also - they are
necessary when it's cold. For easier driving during warmup make sure your
air intake flapper valve is working so you are pulling air from around the
exhaust rather than in front of the radiator.
I'd cover up about 2/3 of the radiator with cardboard for the duration of
the cold weather also. Your thermostat will regulate the temp but a radiator
full of very cold water may chill your engine before the thermostat can
shut it down, giving you poor temp control in very cold weather.
A field expedient that some would call cheating is to take a spray can of
starting fluid and giving a shot of it into the air cleaner box. (Don't
smoke while you do this.) It sometimes works wonders although you shouldn't
need it. It may also attack paint so be careful where you spray it.
One more question - are you using "winter" gasoline? The gasoline sold in
hot weather has a lower vapor pressure (= higher boiling point) so it doesn't
vaporize as well in cold weather. Winter gasoline has butane and other
higher vapor pressure components blended in so that it will vaporize when
the weather is cold. (In very hot weather it tends to evaporate faster.)
So if your gasoline is some you bought in July or August, a new tank of gas
might be helpful.
Also if you are running on the lean side that adds to the problems.
