Steve - yes, the number on the brass tag. I have both the BB1D and the 517s (there should be a 5 in front of the 17s). Someone on here will want the BB1D. Jon

Peter - the manufacturer has a 350 page manual that covers every contigency in detail for chrome plating and chromate conversion on zinc. 375 of those pages are dedicated to safety. Not a bad idea, as chrome is DANGEROUS, as is the chromate conversion. I have no interest in doing these, just in the copy cad. The copy cad is not real cadmium, but a look-alike, I think using zinc. Trying to find out a real world procedure from someone who uses it. While I am paranoid about safety in my shop, if I have to wear a hazmat suit to zinc plate a few carburetor linkage items (for convenience, not economy), then I will sell the unopened kit at a loss; and continue to mail plating to a custom plater.

The brass ones are still available new; but given the country of origin, the "cone" is probably square! Jon

I failed to see the "pint" comment. Do you have a cat in the garage using the catch can as a restroom? The liquid color would be about the same. I would agree with gamekit that the shutoff valve is faulty. Jon

About 65 years ago, we lived on a farm, and had a pair of John Deere tractors. I ran the newer (1951) model, and Dad used the older (1940) model. Dad told me "ALWAYS shut off the fuel valve, and allow the engine to run out of gas before turning off the key. These tractors have gravity feed to the carburetor, and a spot of dirt will cause the carburetor to leak". One day, came in for lunch, both for me and the tractor, and was in a hurry. Turned off the key, filled the gas tank, and when in for lunch. When I returned from lunch, there was a "wet spot" of approximately 14 gallons of gas under the tractor. My Dad never went to college, but he was one wise man! He said "fill the tank, you can't plow with an empty tank". He then hooked a chain from his tractor to mine, and pulled me away from the wet spot (which more or less dried in a few days), and we went back to the field. NOT ANOTHER WORD WAS SAID ABOUT SHUTTING OFF THE FUEL, AND NONE WAS NEEDED! There was no punishment, except in my mind. I guess 14 gallons of 10 cent gasoline was a pretty cheap lesson! An electrical relay, with an electrical shut-off valve (like is used with dual fuel gasoline/propane systems) wired into the ignition system will prevent the issue. Jon

Anyone here use Caswell's Copy Cad home plating outfit that would answer a couple of questions for setting mine up? Thanks Jon

Check my previous post. Tom at Then and Now should be able to identify the origin of your fuel pump, and should have a rebuilding kit available. Jon -
Would like a expert advice on placement item on carburetor

See thread 1964 Buick 3665s in the General Discussion forum. Jon -
I spent the last hour and a half scanning this thing (I don't have the $12,000 scanner to do it easily ) As reported in the other thread, the tag is on the pump side of the carb in the rear. The tag is part number 107-32 and is BLACK! The carburetor was released to production on 2 May 1963. Jon

The TX-2 is what is referred to as an S.A.E. size 2 carburetor. The S.A.E. size 2 carbs were listed as being a "nominal" 1 1/4 inch carburetor. This terminology confused some early documentationalists. I don't have a good one to measure, but most Stromberg size 2 carbs have a 1 and 7/16 inch throttle bore. The size 3 would be 1 11/16 inches. The Carter BB-1 289s or later 289sd both have 1 1/16 inch venturii. As all BB-1 Carters are straight flange, either would require a cross-flange adapter. Jon

Wayne - think outside the box! Maybe Tom will have the tag color (should be unique for a specific carburetor identification number). Make a trip to the store, and look for beverage cans (anodized aluminum). Find one (hopefully with a beverage you enjoy), buy the can, drink (or drain) the beverage, and use the tag shape you have as a pattern, and cut your own tag! Jon -
The Packard 1934 Super 8 used fuel valve assembly P-18914. P-18914 is composed of P-17924 seat, P-10666 gasket, and P-17810 valve - no clip. Jon

I don't have all of the Carter prints digitized. If the identification number is supplied, I will check to see if I have a microfilm copy. I checked a LOT of Chevrolet and Pontiac prints, and all had the tag on the pump side of the carburetor, the screw in the back (2 o'clock). Some of the later Chrysler carbs had the tag on the pump side, under the screw just to the left of the pump. Jon -
The long answer: The original Senior 6 was equipped with a Stromberg TX-2, with a 1 3/32 venturi (largest venturi Stromberg put in the TX-2). THE CARBURETOR WAS TOO SMALL! Stromberg also found that the 1 3/32 venturi was TOO LARGE FOR THE THROTTLE BORE OF THE TX-2, impacting the vacuum signal. The largest venturi I have found in the UX-2 is 1 1/16 (same throttle bore as the TX-2). VERY EARLY in the life of the Senior 6, the TX-2 was replaced by the UX-3 with a 1 1/8 inch venturi. As the UX-3 has a larger throttle bore, the venturi could also be larger. Jon

The short answer: Stromberg did NOT sell a UX-2 to Dodge for the Senior 6. Jon

The letters/numbers stamped on the rectangular brass tag by the choke lever should allow identification of the carb. Looks like a tractor carb to me. Jon

Pot metal (not really good on some components)

Most Stromberg OE-1 carbs were brass; a few were aluminum. I am not aware of one that is zinc alloy. Jon -

1934 Buicks for domestic (US) sales: 40 series would have a downdraft duplex (2 barrel) carb, either Stromberg or Marvel 50 series would have an updraft duplex (2 barrel) carb, made by Marvel 50 series would have a pressure fuel pump, A.C. number 1521538. How much of the above is applicable to export, I do not know Fuel pump rebuilding kits, if needed, may be acquired from "Then and Now Automotive" in South Weymouth, MA. Tom will want to know the number (generally 4 or 5, but sometimes all 7 digits) stamped on the edge of the mounting flange. Carburetor rebuilding kits, if needed, may be acquired from "The Carburetor Shop" in Eldon, Missouri. The TINY 10-???? number stamped on the UNDERSIDE of the carburetor is required. QUOTE: "It also suffers from cutting out due to an intermittent fuel issue" END QUOTE If in fact there is a pressure pump, the "intermittent fuel issue" may be ignition rather than fuel. I apologize for the quality of the picture; I do not have an easy way to convert PDF files to a format that this forum likes. The only easy way is to snap a picture with the cell phone, which can easily be converted. The picture is high resolution, so it may be downloaded in a format your computer likes. Jon -
The chart is incomplete, as is much data in repair manuals, as they are generally printed prior to the product of the vehicles. Both engines had these carburetors discontinued, and different carbs replaced them mid-production year. The 40/50 7-42 was replaced by 7-46, and the 7-43 was replaced with 7-47. This took place 25 March 1941. The large engine 7-39 was replaced by 7-44 an the 7-41 was replaced with 7-45. The large engine replacement was 24 March 1941. 7-46 was held over for a part of 1942, but then replaced. The Carters also had early and late production. Jon

Wiith the progressive linkage, the engine got a reputation for horrible fuel economy; and then fuel rationing entered the picture. The fuel distribution in the various cylinders is not ideal. This is the idea behind using straight linkage. On a similar note, I used to regularly rebuild Chevy 6 cylinder carbs that came in with the accelerator pump disconnected. If you only can acquire so much fuel per month (and not very much), you tend to try to save what fuel you can. Jon

FOR SALE: a COMPLETE SET of Sun tuneup charts from 1956 through 1982. In a different lifetime, I used to sell individual charts (along with A. E. A.) charts at swap meets, but I would never sell the last chart. As far as I can determine, Sun first published these in 1956, and 1982 was the last year. These charts are 9 x 12 inches, and most are double sided. Each chart covers all kinds of electrical information on an individual year, make, and model of automobile. These are automobile only, no trucks, etc. Will be happy to email anyone a pdf file of a scanned chart; not posting here because this site does not accept pdf files, and my scanner will scan directly to Adobe, but otherwise the output of the scanner has to go through a 3-part exercise to convert to a JPG file. The charts were originally contained in large metal boxes. The boxes go with the set, although I currently have the charts in a file cabinet for easier access. There are 2083 cards in this set. Check the "sold" columns on Ebay, folks are paying from $10~$20 PER CHART for individual charts. Since this might be the only complete set still in existance, I really want to sell it that way. Possibly some folks with library affiliations may see this post. Price for the 2083 cards, and 2 metal cans is US $2500. plus shipping. I haven't weighed the cans/cards (I cannot lift one of the cans full of cards anymore), but definitely in excess of 100 pounds. So shipping charges will be more than a few dollars! Of course, if you visit The Carburetor Shop, and pick up the cards in person, there would be no shipping charge (and while you are here, possibly we could find room in your vehicle for a few carburetors! ) Also will be listing a complete set of the A. E. A. tuneup charts, but I haven't counted the charts. Watch for this listing. 573-392-7378 (9-12, 1-4 Mon-Tues central time) or message. Jon

From the Tillotson factory manual: "GASOLINE LEVEL - To obtain proper level, remove upper half of carburetor, turn UPSIDE DOWN and with the float lever resting on the inlet needle, carefully bend float lever to give a distance of 1-13/16 inches from the face of gasket to the top of the float." From The Carburetor Shop School of Hard Knocks - GASOLINE LEVEL - DON'T bend the float lever, IT WILL BREAK! Acquire a selection a round gaskets of the proper diameter, and varying thicknesses. The gasoline level may be adjusted by varying the thickness of the fuel valve seat gasket. Jon

Any idea what this Carter AFB Carb part does?
carbking replied to DannyGarcon's topic in Buick Riviera
As mentioned, original purpose was a hot idle compensator. But Pontiac found a more nefarious use: Take a look at the picture. The item on the left is the Buick hot idle compensator. The item in the center is the Pontiac hot idle compensator, with RPM and performance limiting "wings". The item on the right is the "dummy" performance limiter added to manual transmission Pontiac AFB's to assure that the more expensive tripower engine would outperform the less expensive 4-barrel engine. Hot idle compensators are normally used ONLY on carburetors on engines with automatic transmissions, except the dummy! Most of the tripower engines are rated 200 RPM higher than the 4-barrel engines. There is just enough air deflection and resistance to restrict WOT RPM. Note that since these are on the secondary side, performance is not impaired until WOT. The numbers are the original Carter part numbers for the items. Jon
