Holley jet ?

Looking at Holley's numerical listing, it should probably have a 70 primary jets, 80 secondary jets, .028 primary squirter, .031 secondary squirter...sounds like it's pretty close to that. You can reference the chart with the number from the front of the choke horn for a baseline. You could also try abodyjoe's setup, though it's a different carb on a different car and may not work as well for you.

Removing the choke is most likely the cause of the cold running problems. If you mess with the jetting, idle mixture, and squirters to get it to run well cold, it probably won't run as good when warm. You can either live with the cold running problem or put the choke back on.
