My car does that as well. I pull the choke out all the way when I start until its running. Then I slide the choke in until about halfway-ish or so until the car warms up. Once the car is at temperature, I push the choke in and go on my merry way. Easy peasy.
It could be just the choke, it could be the carb needs to be slightly adjusted, but either way its super simple and I wouldnt worry about it.
