What's a Carburetor, Dad?

The carburetor on the Old Blue has a problem. When I'm driving and come to a stop or turn a corner the engine dies. To alleviate in recent weeks, whenever we come to a stop sign or light, Cricket reaches over and pulls out the choke a little to keep the engine running... so Uncle Ken has sent a carburetor with the marking C5TF C  (the one on the truck is marked with  the same) and encouraged us to swap out the old carburetor for the rebuilt one he sent. I'm trying to find what we have here:

Once again the guys at the FTE forums are all over this stuff ...

1. The one or two letter carb ID tag suffix identifies the type of carb, what its applications are.
2. The carb ID tag prefix of C5TF was used with many 1965 (1966/69) series' of trucks and was the 1V, 2V & 4V Auto-Lite & Holley carbs.
3. If you don't have or know what the suffix is, you're SOL
4. Post 25: C5TF-B or Y = 1965 F100/250 352 Auto-Lite with M/T / No such thing as C5TF-D
A few more examples:
    C5TF-C = 1965 F100/250 352 with A/T.
    C5TF-H = 1965/67 F100/350 240 Auto-Lite 1V with A/T.
    C5TF-N = 1965/67 F100/500 300 I-6 Auto-Lite 1V with M/T.
    C5TF-AH = 1965/69 N500/600 240 I-6 Auto-Lite 1V with M/T.
    C5TF-AU = 1965/66 F600/800 361 Holley 2V.
There's at least 30 more C5TF prefixes for other carbs.

Another site says: "This carburetor was made by Ford , . It is a F2-2100 . This carburetor has a part number of C5TF-C and used on 65-66 Ford trucks""

So we will add this little task to the "Todo" List and read up on what it takes to swap in a rebuilt C5TF C.
