I picked up a 1961 F-250 late July and drove her 2,000 miles home over the Rockies and across the plains in 95 F heat. All went reasonably well given any number of getting to know you surprises. I was doing 10 - 15 mpg at about 60 mph. Idle could get rough and fall out after hours of hot running. Couple mornings it was hard to start after a day's work. So I am suspecting a leaky manifold gasket and the carb could use replace/ rebuild. This is the 223 cu 6 cyl with a 1bc carburetor. The only markings I can find on the carburetor are: 12 R 1958.
So can anyone help with the following questions:

1. What is the carburetor on the F-250?
2. What replacement carburetors can installed (and where can I find those)?
3. Where can I get a rebuild kit for the existing carburetor?

Thanks so much for the help. I think it will make a difference.

Thank you Bill. I cannot ask for a better answer than that. I told after the post that 12 R 1958 is only a casting number. In my wanderings I have also run into The Carburetor Shop.

 

I am looking for a rebuild kit too for a single barrel on my 1963 f100 shortbed. Its the original carb for sure but I dont know what kind. Hres a pic..

 

Hey Matt, Tough to tell from the picture. That air filter is definitely not stock. Call The Carburetor Shop ((573) 392-7378). I did not try Green Sales (800 543 4959) per Number Dummy but no doubt they will get you the rebuild too. FYI, The Carburetor Shop did not have a replace, just the rebuild kit.

 

should be a model 1904 holley

 

the 1904 is for the 1961, the 1963 could be a ford f-1 model 1100 ,holley models 1940 or 1909

 

i like the 223, my 63 merc longbed has one and after i got it home and tuned up i had to flush the fuel tank and replace the steel supply lines to the carb. i went to my local parts store and they hooked me up with a reman carb. i keep abot 80 to 85 kph(50-55mph) and get 23 to24 mpg. these little sixers have a nice sound and rythym at that speed (should check with a tach one day ).
the carb i put on was an autoline reman, i'll have to find the bill to get a part number, but these things are available and reasonably priced
