By design, the choke plate tension is set by the index position of the black cap that covers the choke housing, unless you live where it's really,y really cold, that index is usually best set at the middle mark. Once set, there is a small vacuum operated diaphragm (called the choke pull off) on the right side of the carb that is supposed to pull the choke plate open to a specified position when you start the engine. you set that opening by inserting a specific drill bit between the carb throat and the plate edge and then bending the small linkage that attaches the diaphragm to the the choke plate. If you don't have the carb with the pull off, there is screw near the top of the choke housing that you adjust until the plate has a 1/16 in gap. this should be done before the choke spring is installed. You may need to Google for a photo of your carb to see what i'm discussing if it isn't apparent to you.
If this component is malfunctioning it will result in what you've described.
