Carb ID
I have a 67 ford f-100 with a 240, the truck is running rich right now and I think it is a stuck choke. Can anyone help me id the carb, it is a Carter with numbers 2253 and 7186S near the bottom.
Thanks in advance

Hi,
Not familiar with that particular carb but most chokes work about the same.When the engine is up to operating temp is the choke butterfly open all of the way? This is the large hinged "flap" on top of the carb.
What gives you the indication the carb is running rich? Black smoke, strong smell, fouled plugs?

I went to carbs unlimited to see what I could come up with for you and using one of the numbers you gave it came up as a Holley 1 barrel.. But they do have good pictures that may help you in finding out what you do have.. I don't give up easy, so we'll see what comes up..

You have a Carter YF-1A carburetor. The float level on it should be 7/32nds of an inch. The idle speed adjustment screw should be 1 1/2 turns OPEN. The idle speed should be 550 RPM with an automatic transmission and 650 RPM with a manual.
2253 is the Carter casting number for the unit; 7186S is Carter's model number for the YF1A unit.
Is there a surviving Ford carburetor ID tag on it? For a 67, it should read SOMEWHAT like C7TE-9510-A. The 9510--base number for a Ford carb--may or may not be on the ID tag. Then again, the tag may be gone after this length of time. But, with the 7186S number, if need be, you should be able to get parts for it if need be.

I went and checked a website about the YF-1A Carters on the 67 F-Series. According to it, the Ford ID number should be C7TE-9510-S or C7TE-9510-T.
According to it, the 240s all used the Carters and the 170s all used Holleys.
I hope this helps you some!

Thanks for all the help guys, yeah i have all the symptoms black plugs, black exhaust and the strong smell. There is no id tag still with the carb. Is the YF-1A the right carb for the truck, it seems like it was rigged up from another vechicle.

I checked Ford, Motor, Chilton, Haynes, and Clymer--although I am not much of a Clymer fan at all--and ALL of them specified the Carter YF1A for your 240 and a Holley for the 170. I had two Ford F100's with 240's--a 67 and a 74--and both of them had the YF1A.
Does your 67 have a manual choke or electric choke? Insofar as I am aware--although, admittedly, I could be wrong--all the 240 and 300 Sixes before 1973 used a manual choke. IF that is correct and you have an electric choke, then someone put that particular carb on your 67 from an engine built after 1973.

It is a manual choke on my carb, it just seems like it is missing parts because there are brackets mounted on the side of the carb with nothing on them. Also should the carb just be sitting on the exhaust manifold with a spacer between them, because this carb sits on something(not sure what it is but has a part number E2TE-9D448-N1A)
Is there any manuals that would show how the carb hooks up to the engine that you know of?

If memory serves me correctly, 9D448 is Ford's base number is for an EGR valve spacer plate for an 82 F150 with a 300 Six. The 240 was stopped after the 74 model year. For a pic of the YF1A on either a 240 or a 300 Six--or, alternatively, a Holley on a 170 Six, try visiting www.tocmp.com. Or, you can look at a Chilton's or Motor's or Hayne's that covers the hand choked carbs. I have several views of them but I am afraid I've no idea of how to get it from the book page to the Net.

Although, admittedly, it looks somewhat as if the carb is sitting on the exhaust manifold, if you look at it closely, it is sitting on the intake manifold. If you look, both manifolds are so close together, they almost appear as a set. You MAY not need another carburetor, but you need a spacer plate that matches the intake. Take a look at the intake manifold and see what its casting number and casting dates are. If you let me know what those numbers are, I can tell you the year and design year for the intake manifold.
