Tell Me A Choke

I have a ‘68 Plymouth ‘Cuda I’m wondering what possible reasons
there are for my engine running way better in warm weather (68° F and up) and crappy when it’s cold out (45° F in the morning).
The engine is bone stock except I’m running a 1405 600 CFM Edelbrock. I’m
told this carb is jetted on the rich side, no choke, so you’d think it would be better when it’s cold out. What could I be missing?

You’re missing the reason that all OEM
carbs have chokes! When cold, atomization
is lousy, so much more fuel must be
added to keep it running.
