Motorcraft 2100 carb Qustion HELP CHOKE

I installed my Motorcraft 2150 carb with electric choke few months ago along with team rush upgrade. its a (4.2 90 wrangler) nuttered and timed..all that done correctly. MY problem is it sometimes dont start right up and sometimes does. Like sometimes ill get in there turn the key giv it some gas and feel like its goin start and let off and its like putting or something.. like starving for gas or something. I beleive it has to do with the choke. It runs really good and strong besides that with no misses or anything.
My neighbor told me that there are settings for summer choke and winter choke...When I installed this carb I did no settings on the choke at all can anyone help me out on this? I know the problem im having is just a simple fine tuning that I never had done.

I hope this helps, Adjustments are very easy.
I always pump the pedal twice before starting from cold and tickle the throttle as needed.

Alot of the how much you adjust the electric choke depends on where you live and how cold it gets. Here in Colorado 2 times per year at least. Negative temps all the way to 100 requires several adjustments along the way. I like the manual style better for that reason. I never have any trouble with a manual choke being the problem for cold start issues. I have one vehicle left with a electric choke and soon it will be manual.
