Possibility #1: '84 Accords had major cold start problems and there was a service bulletin issued in 1984 to install a "cold start driveability kit". I think it was some sort of insulator that went between the carburetor and intake manifold. Hard to say if those parts are still available, and anyway, I'd be very surprised if your car hasn't had it done already after 20 years.
Possibility #2: Yes, your car does have an automatic choke. I used to own an '84 and got very familiar with its cold weather behavior (lived in Iowa at the time, no garage, but it always started). The cold start procedure should be: push the accelerator to the floor once (2-3 times if it's very cold out), then turn the key with your foot off the gas. It should fire right up if it's not like 20 below or something -- when it was that cold, I usually had to hold the gas pedal down about halfway while cranking. You'll know if the automatic choke is working because those things had a screaming fast cold idle (like around 3000 RPM). Let it run like that until it seems to be running smoothly on all cylinders, then tap the gas and it should drop down one notch. The idle will not drop the rest of the way down until it's good and warmed up. If the car starts OK, but won't stay running without your foot on the gas, I'd suspect the choke.

Acts like the automatic choke is not working properly (if it has one). Once it warms up or comes out of the garage warm it runs fine. Any suggestions? Thanks in advance.
