carburetor problems
hey everyone i have a 1976 ford f150 it has a 400 from a 77 ltd, i dont know what carburator came with it stock. in lmc truck they have a 2150 regular and a 2150 for a automatic transmission but how do i know what carburator i have, the part store said there should be a tag on it but i cant find it. anybody know if that is the stock carb and which one i should get because the ltd was an automatic and the truck is a 4 speed.

The difference is the kickdown linkage. The LTD would have had an automatic, so it has the kickdown linkage already. Since your truck is a 4-speed, there's no need for kickdown linkage, so you can get the standard carburetor, regardless of the fact that your current carburetor went with an automatic transmission. What matters is the transmission that's in the vehicle with which you're going to use the new carburetor.

thanks for the information didnt really know about the kick down and another question it has the electric choke but i dont know what wire goes to it because it isnt plugged in. and would it be better just to switch back to a manual choke because it already has one in it its just not hooked up and im not really sure how to hook it back up and what parts i would need to do this?

The stock carburetor's electric choke is powered from the stator (S) terminal of the alternator. It also uses a metal line to draw in fresh air heated by the exhaust, hence the term "hot-air" choke.

As far as the manual choke, some people opt to go this route because it's cheaper and easier to fix than an automatic choke. The advantage is that it gives you more control over its operation, but the disadvantage is that you have to mess with it yourself. Many people claim that automatic chokes are too much trouble and never work properly, but the truth is that if set up correctly, an automatic choke can be problem-free for all four seasons. As such, most choke problems are user-error.
In the interest of answering your question, most manual chokes come in a conversion kit with the cable and the brackets necessary to connect the cable to the tang that the automatic choke used to operate.
