Those diagrams come with the rebuild kits.

If your diagrams from your rebuild kit doesn't show your part, you might have gotten the wrong kit for your carb.

Most carb rebuild kits will have several different diagrams because one kit will rebuild several different carbs. However there are several different kits avaliable as well, and each one is for a different set of applications.

The best thing to do is to get either the casting number off the carb; It's a 4 digit number with a possible 5th letter on the throttle body as example: 7429 or 7429S; or use the carb tag number if it's still attached to the front of the carb. That will insure the correct kit is being purchased for the paticular carb.

People have been known to swap carbs without thought to correct application though.

 

I think misguided swapping is exactly what happened in my situation. I have a Holley reconditioned Carter Carb, I believe is not the OEM model. NO TAG, only a Holley sticker which corresponds to a YF, the casting number is 7051s and as far as I've been able to tell I have a D5TE-AGB Carburetor. Holes have been plugged and it has an electric choke which I don't think it came with??? I've seen a couple online that look exactly like mine but with the climatic choke. All the diagrams I have including the one which came with my kit DO NOT show that part. I even purchased an e-book which was supposed to be for my model, and it was very helpful, but DID NOT, show that part. So did the goof ***** add a part I don't need or what?

 

Well this YF was installed on certain models in the early 80's on canadian models and certain vehicles over 10,000 GVWR only.

Check to see if your truck isn't a canadian model.

If it's a USA model, then someone swapped it out or you have a F-350, as this carb was also used on 1978 and earlier 300's here in the states.


What are we working on? Year Model? F-100/150/250/350? Transmission, etc...

Also the chokes on the 80's models are electrically assisted thermostatic chokes. So they are basicly both.

 

7051S is the Carter number. Most parts catalogs list carburetor numbers to kits. The problem is most places are all computerized and the kids working the counter don't generally know how to access the cross reference.

 

1982 Ford f100, 4.9L Six, C6 Tranny and it's a U.S. model according to the VIN and it's GVWR is 4750, so it's a little guy. Are you saying the 80's model chokes worked the same as Climatic chokes without electricity? I thought Electric chokes needed a constant 12v line in order to work properly.

 

I haven't figured out which engines used the electric choke and which didn't. Dad's '81 351M F150 4x4 had the electric choke heat stove but it had never been hooked up from the factory - no wiring for it nor marks on the connector. Instead it relied on the hot air stove from the exhaust manifold. That is, it did until the tube rusted in two for the hot air stove and the choke didn't come off. So, I hooked the electric stove up and it worked fine.

The factory shop manual shows the electric choke in the wiring diagrams but doesn't designate which vehicles used it. And, the other '81 I have, Rusty, doesn't have any wiring for it either. Based on my very limited experience of two 81's, two 82's, and one 85 I would say that not many of them came from the factory with the electric choke in service. But, maybe someone can clarify this?

 

Go to napa for the rebuild kit, they seem to know whats what a lot better than most other parts stores.

 

Gary, that's interesting, I hadn't learned that yet. The wire was not connected but either was the tube. Actually I'm still trying to locate where that tube goes. The Guy I got the truck from had the heat tube hole plugged with a plastic screw.

 

immto, the choke heater is a 7 volt unit on a Ford and is fed from the stator terminal on your alternator. If you have the infamous 2G alternator it should have a pigtail on the alternator harness.

The heat tube goes to a hole on one of the exhaust manifold runners either number 4 or 5, it will be the one behind the center of the manifold set. You will probably need a choke tube repair kit if the tube broke off in the manifold (very common). If you have a long enough 1/4" drill bit to reach the hole, you can simply drill it out to fit a piece of 1/4" tubing.

 

Thanks for info 85Lebaron2, I hope to have time to mess with it again this week. I also messaged Kyle to see about getting those diagrams to help solve my carburetor mystery.

 

I think the wire off the stator to the choke is white/black-stripe.

 

Hey another problem you guys might be able to help me with is since the kit for my Carb didn't list my make and model, since it probably didn't come that way stock, I had to kinda guess at the float distance. Any thoughts?
