When cranking my car I have to keep the throttle at about 2,000 rpms to keep it running. As the motor warms up the throttle response and idling of the carburetor goes back to normal. Is their a solution, maybe some adjustment on the carburetor that I could try to help aid in fixing this problem?
Thanks

It sounds too lean at an idle OR the plugs are a bit too cold.

Reduce the idle air bleeds about .015 OR try a hotter plug and check the effect. AIRBLEEDSDOMVENOM.jpg

Forgot to mention, it is also very hard to get the motor started. I'll be honest I haven't touched the idle mixture screws since taking out of box, simply due to my little knowledge of working with carburetors. Currently running AR3934 plugs.  Should I see where the idle mixture screws are set? Thanks.

They should be between 2-3 full turns out.

If they are already that far out, then go smaller on the idle bleeds.
