Default What Model Carb?

What model carb am I looking at here? There is no stamped number (like 97) that I can see. Also, are the tops hard to come by? This one is broken where the throttle linkage attaches. Thanks.

I'm not an expert but it looks like an early 97. Cain't read that circle on the bowl, can you post a better pic. Walt

I'm no expert either, but it's definitely a model 48!

Thanks guys, based on my looking at 48's online I was coming to my own conclusion, but I appreciate confirmation.

Question for our resident carburetor rebuilders. What distinguishing features would allow someone to quickly identify the difference between a Stromberg model 40 and model 48 from say a few feet away?

Well, nothing is a safe call at 10 feet because lots of the differeces interchange and many elderly carbs are mixtures.
A relatively big difference visible on the one up above is the right side linkage...a 97 choke lever would have a tab at top rear with a little hole in it and the casting would have a matching boss to hold the springloaded widget that secures choke in off position. Naturally, many free-range 48's now have 97 parts there...
Now, spot a 40 in a pile of 48's...

The only surefire way I know to spot a 40 is to remove the airhorn and examine the idle transfer channels, or lack thereof.

That's a little harder,there are NO small # 48 on the top lip or the lip of the middle section indicating a 35-36 #48. Best way is as Max said is open it up. OMO ken ct.

Everything else, like the cast-in Stromberg part numbers, requires serious scrutiny... however if you can read those at 10 feet, the Air Force may well have a good career for you. Or maybe the East Overshoe Bird Spotters Club...
And never trust anything that is removable, as a bunch of the 48's I have contain a generous sprinkling of 97 type parts, and some of the 81 and 97's have 48 stuff...
At the core, the main body casting is the main thing I guess.
After 75 years of commercial rebuilders, hotrodders, and farmers messing with old Fords purity is hard to find. 94's are even worse it terms of mixed part possibilities!

Yes your right Bruce,many parts are changed around by limited knowledge people,they may fit but not work quite right ,ive seen everything in the book on these bastaredized carbs. You have to know what goes with what. Assumeing a person has a good supply of cores and parts most can be brought back to original to the year of all correct parts. OMO ken ct.

Thanks for answering my question gentleman....
I can ID the 81's, large or small 97's, and 48's, but on some of the Stromberg cores I have there are no outer markings that I could find that would have put them in any of the previously mentioned Stromberg number categories, so I am thinking they are most likely 40's.

FredB, I apologize if I took your original post off course.

The people that rebuild them will have gauges to measure the venturi size
but it can be easily measured with a set of home made inside dividers made from a piece of 1/8 welding rod or a coat hanger..

"many parts are changed around by limited knowledge people,they may fit but not work quite right"

There are also carbs that are assembled with mixed parts (like 48/97) by very knowledgble experts to yield superior results for high performance or special purpose applications. Just say'in.

Model information, like 48 and 67, is missing from many of the things, especially the early models and 97 types made long after Ford use, but Stromberg was pretty good about putting the size in tiny print on the right side of the bodies.
