Default Carb problems

Ok so I have a 85 f150 with a straight 6 that is having some carb issues. First of all there is no ID plate on the carb so i'm having trouble IDing which carb i have. I beleive that its a carter but unsure of the model. Second The butterfly air inlet will not open up once the engine warms up. The choke has an electric choke which someone wired into the alternator however it's not receiving power(where should the electric choke wire into?) It appears that at one point there was a choke with a vacuum pull off because I found a vacuum line that was plugged that wrapped around to the left side of the carb. Next The throttle position sensor is currently disconnected once I found the other end and connected it the truck would bog down as you got up to speed so I disconnected it(Do I really need it?) I'm trying to adjust the carb but right now until i get all the other bugs worked out I'm kind of stuck. what should be my best course of action? Below are some pictures of the carb I have.Click image for larger version

You do need a properly adjusted throttle position sensor. For the choke, you can convert it to a manual choke.
