Rebuilding it is cheap and will most likely work out. If it is too worn out, you can still get a new one and are only out a few bucks (maybe nothing if you sell it for parts).
This guy has good kits and you can watch all the videos for a step by step breakdown of how to rebuild it. Get the best kit you can and get all the stuff for your choke. Let it soak in cleaner for awhile as it probably has a lot of varnish.
Then check all your vacuum lines, set the timing, and tune the carburetor in with a vacuum gauge.

I agree with everything above. How many miles on it? If the OEM factory carb is rebuildable, and they generally are, most people will be better off in the long run for most purposes. With long use, the throttle rod, that the butterflies attach, will waller out the holes in the carb body and introduce a vacuum leak. This is something to look for.
The problem with rebuilds or remanufactured carburetors is they may have been "mixed and matched" Frankencarbs with parts that aren't quite right for the application. It is a gamble buying one, no way around it. What is important is that you kind of go through everything one step at a time. Everything. Plug wires & ignition, distributor, cylinder compression, vacuum gauge, get in the manuals and make sure everything is at factory spec. Even the correct thermostat will make a huge difference in how it runs. Most of it probably doesn't cost anything other than your time. There's a certain logical order to a tune-up, if the ignition isn't right, the carb tuning that follows will be problematic. The shops don't do this stuff anymore because they have to charge too much, but that's how you'll get it running down to the gnat's ***.

Hey guys and gals! I need some advice, please!
What I got:
1973 Ford F250
it runs the 390 V8
Automatic, 2 Wheel drive
ALL ORIGINAL - until after I start messing with it.
What I need:
Well, as the title says, I need a new carburetor, with an electric choke, and 2 barrel.
My options:
I really have no idea. I can go with the Motocraft and know that it will fit and work, but I would like something with more power, I do not care much about gas mileage, this will be a hunting rig, so it needs to be able to get up and down, and tow a trailer. From what I have learned recently, Edelbrock is out because they do not create a 2 barrel carb.... WHAT???
I am sure there is a Holley, but will I need an adaptor, or is there one that will bolt right on? I tried to figure this out, but I couldn't. Are there any other companies I should look at? is 500 more or less than the original Motocraft (or whatever it is that came on the truck originally).
Thanks everyone! I am excited to start rebuilding this vehicle once I can get the choke issue addressed, and get it running. I will possibly keep a thread in my introduction on how it goes, with pictures! lol

Plus the swap to a 4BBl Aluminium intake will shave about 60 lbs off the front end.
