Is older carb chevy 350 normal to not want to stay running until hot?

Its a early 80s 35o motor with a holley 4bbl 750 carb. I am wondering if it is just one of those old car quirks to need encouragement to stay running on startup. when started, the rpm will just fall too low and it will stall out unless tapping on gas. After its warmed up or on hot hot summer day, it doesn't

The automatic choke needs to be inspected and the carb needs adjusting. If the vehicle has been sitting for a while the gasoline may have had ethanol in it and plugged up the jets.

Holley 750 on 350 is way to big.
Choke is out of adjustment.
May be jetted wrong………………..Go to a 600 cfm or max 650.But best yet is to get rid of Holley and put the stock 4 bbl QJ …it will run way better.

Hi simple it needs so sort of choke mechanism this produces more fuel to the engine during the warm up period.

Sounds like an automatic choke problem to me.
