cold car STILL wont start!

[rfisch]

My 65, unfortunatley, had to sit out over night because the garage is full of the new cabinets for my house and now it wont start. It ran fine yesterday when I took it out of the garage but this morning when I tried to start it it would only run for about a half second then die. I initially thouhgt the fuel line may have had some condensation that froze so I unhooked the fuel line at the front of the carb and turned the key for a second and it seems to be working fine, so then I took the carb off and took it inside to clean it thinking that it may have had a small piece of ice in it somewhere causing the problem but I had it inside for quite a while and cleaned it really well, replaced some gaskets, adjusted the choke settings and what-not, but when I put it back on I still got nothing. It got down to about 5 degrees over night and I know I shouldn't have left it outside but I also know that it got that cold back in 65. Now I can't even get it to fire using starting fluid. The plugs and wires are only about 5 months old and seem to have stayed dry. I just can't seem to find a problem anywhere. Can anyone help?
