Too cold to start car

My current carb was setup for drag racing by the previous owner (or actually it was the guy before him). No choke, larger jets, and power valves plugged. About 2-3 years ago, the gasket around the metering block was leaking so that's when I rebuilt the whole thing and put it back to stock specs with the original jet size and power valves. I'm definitely no expert, but I watched plenty of videos and bought a few books on holley carbs. And it ran fine for the next year without a problem until my cam snapped and destroyed my entire engine.

A heater wouldn't work for me, my house has no outlets on the outside except for the one on my porch I put it. I'd have to run an extension cord halfway around the outside of my house or leave a side window open.
