  1. As we are no longer restoring carburetors, we are offering many of our made-in-the-USA rebuilding parts for sale. If you have an interest in Packard Detroit Lubricator parts, please check my Ebay auctions under user name carbking Jon.
  2. Thank you Tom, I will list them. Jon.
  3. Keiser31 talked me into it; something else for the kids to say "why did Dad buy this thing?". I will take it, PM sent. EDIT: For the record, Vernay was one of two companies producing these neopreme tips; the other being the I.E.R. Corporation. Jon.
  4. Tom - if would be too much to ask. I need to find a book so I can get part numbers for the various kit components, and then then are probably Buick numbers, will have to cross-reference them to other Buick carburetors for which I have the Carter bill-of-material. Then I will be able to offer rebuilding kits. Jon.
  5. A wee bit more information from some additional files: The airhorn casting used on the 4050s is shared with 3645s The lower casting used on the 4050s is shared with unique The airhorn casting used on the 4051s is shared with 3634s, 3646s, and 3924s. The lower casting used on the 4051s is shared with a BUNCH of different Buick carbs 1964, 1965, and 1966. I believe this exhausts the information in the files of which I have custody. Does anyone have a late 1960's Buick Master Parts book to check? Jon.
  6. Carb Kit

    Yes, but will need some carburetor identification. 573-392-7378 (9-4 Mon-Tues except holidays). Jon.
  7. What was your biggest screw up working on the cars

    Biggest foul-up??? Real easy. Believing I was good enough to extract performance from a Pontiac 301. After a year of frustration, and lots of dollars (conversion to factory turbo, conversion to special-ground cam by a company that specialized in turbo cams, other mods), finally came to the conclusion I had attacked the wrong component for modification. The engine made excellent power from 2800 RPM to 2900 RPM. What I needed was a 28-speed transmission!!!!! Jon.
  8. Tom - to my knowledge, Federal Mogul never owned Rochester (division of GM). Carter was purchased approximately 1984 (from memory). Google probably can give an exact date, but I am lazy. The size and shape of the font changed over the years. I mentioned the single line/double line only as additional information. My GUESS is when the stamps wore out, Carter simply purchased new stamps, without regard to the font. The experimental carbs would be hand-stamped with an experimental number (started with the letter "X"). The prototypes would be stamped with the same numbers as the production, but I believe without proof, that they were hand-stamped. Back to the Pontiac Super Duty carbs. They were what Carter considered "low production". The carbs were built from castings from other production carbs (some Chevrolet, some Chrysler) and some unique parts then attached, as well as calibration changes. The factory stamping from the original application was ground off. Again, I knew the individuals that pulled the production carbs off the shelf, and disassembled for the castings. Unfortunately, they are no longer available for contact to verify this. If the 4050s/4051s DO appear in the Buick Parts Books, I am going to need to find one to produce a bill-of-materials, so I could offer rebuilding kits. Is there any record of how many of these cars were produced? Were they factory, or dealer installed options? The Chrysler "Drag-Pack" dual quads (200 sets) did make the Carter production literature. Really difficult to document this low production stuff, and as a historian, I like to have factory literature as backup for my database (currently 92,584 application entries). Jon.
  9. First - Rochester did not Carter, Federal Mogul did, in about 1984. Carter used a number of different fonts on the stamping of the AFB carbs. Some were stamped with both the date code and the identification numbers on the same line, others on two separate lines. The Carter documentation quoted is from a 3-ring notebook listing done by a Carter employee. There is no evidence is was done by Carter so absolutely no proof of anything, but I know who did it. The 4050s and 4051s numbers never made any of the factory production literature. Generally, with a low "production" number such as the Pontiac Super Duty carbs from 1962 and 1963, Carter would issue a "TFN" which meant temporary field notice. These were done on a mimeograph machine as needed, but were not sent out with the factory Master Parts Books. I do have the TFN file from the office of the customer service people at Carter, and these numbers are not there. The numbers were assigned, and Buick numbers were also assigned, but this means nothing, as the same was true for the 1957 Pontiac dual quads. In the case of Pontiac, numbers assigned, prototype carbs sent to Pontiac for testing, NO production. However, over the years, I have seen a couple of the Pontiac sets. They were constructed from then-current parts, no new tooling was done. I have enough parts to build the exact carbs, if I wished to do so, as I did acquire the actual drawings for these carbs from Carter. Often, prototype carbs would be hand-built BEFORE production for a given year, so NOT surprising that the 1964 throttle shaft may have been used. I have tried to keep my database as accurate as possible, so show these as experimental. I know a few prototypes were built, but cannot prove how many or if these, if any, were actually sold to Buick for OTC sales from the Carter literature. The information I have: 4050s - Buick 1373999 1966 Buick 425 both S/T and A/T front of 2 discontinued 9 Oct 1970. 4051s - Buick 1379226 1966 Buick 425 A/T only rear of 2 discontinued 26 August 1975. It would be interesting to see if the Buick numbers appear in any of the Buick Parts books. EDIT: for brain to typing finger error, the 4051s was A/T only, not S/T as originally posted. Have changed the post to reflect this. Thanks Tom. Jon.
  10. Carter lists 4050s and 4051s as PROTOTYPE dual quads for 1966. I have no records showing that these made it to production, which is why I do not list them in my charts on my website. No use for someone trying to find something that does not exist. Typically, Carter would produce a few carbs (generally 6 or fewer) which would be sent to the O.E. for evaluation. Following evaluation by the O.E., the carbs would either go into a production status or be forgotton. Often, these prototype carbs would also carry the "experimental" number, generally a 5 or 6 digit number beginning with an "X". I have several of these, but none for Buick. If someone has Buick data that would show these carbs were actually produced, I would like to see it, and would then add them to the web-page. Jon.
  11. Pinging when floored

    Here is a link to a really good article on octane: https://en.wikipedia.org/wiki/Octane_rating While it gets fairly technical in some areas, about midway down the article is a very useful chart showing MON, RON, and AKI for a number of different fuels including various gasolines. This chart suggests that 98 octane in Australia/New Zealand would be 93~94 octane in the USA. Here is another article which I did hoping to make the technical more user-friendly. http://www.thecarburetorshop.com/Octane.htm Like others have suggested, I would vote for timing issues. Jon.
  12. Spark knock in a 32 Packard ??

    Came late to this thread, may be able to contribute. Octane is, at best, confusing, because there are three different systems, and the USA has used two different of the systems in different eras. The three systems are: Motor, Research, and AKI (anti-knock index). Here is an article I did some time ago to attempt to explain: http://www.thecarburetorshop.com/Octane.htm As to the carburetor: Zenith carbs from about 1934 to about 1980 have a round tag approximately the size of a dime riveted to the body of the carburetor. There should be at least one, and probably two sets of numbers. If two, then there will be an inner and outer set. The outer set would be the "customer's" part number (eg. Ford, Chevrolet, Gray Marine, etc.) while the inner number would be the Zenith number, and the number that is most useful. Acquiring the Zenith number will allow you to determine the original application, and therefore the applicability of that carburetor to your engine. Packard in 1932 would have used the Detroit Lubricator type 51 carburetor. While an excellent carburetor when in proper working condition, the design is totally different than most other makes of carburetor, and rarely understood by the owner of the vehicle or his/her mechanic. Also, the DL is QUITE EXPENSIVE to correctly restore. Many of them have been replaced over the years. Jon.
  13. For sale - one fully restored Fish type M-1 carburetor from the 1950's. Looks great on your trophy shelf, and is worth its weight in platinum as a conversation piece. And while it is meticulously restored to original condition, THERE IS NO FUNCTIONAL WARRANTY WHATSOEVER, REGARDLESS OF THE APPLICATION! Highly recommend the only application is your trophy shelf! Price including postage within the 48 contiguous United States is $800. Jon.
  14. Tractor carburetors wanted

    CA - We have literally hundreds of Tillotson carburetors. Similar in company philosophy to Marvel, Tillotson changed models frequently, with very little interchange. Generally (certainly not always), carbs with a change in the suffix letter would be sufficiently similar that the rebuilding kit would be the same. Example: Y-7B, Y-7C, and Y-7D would all share the same rebuilding kit; however Y-7A used a different main body gasket. But a Y-7C would be different from a Y-8C, etc. So we have to find original carbs to have for sample pieces in order to fabricate rebuilding kits. These demand for the kits is going to be like that for Marvel kits (a really popular Marvel kit will sell 3 annually!), but we try to have this stuff available. Actually, Tillotson was a major player in the early carburetor market, with their car market share being primarily among the lower priced vehicles, but they did manage a few of the more expensive cars. Tillotson's influence in the car/truck market began waning in the late 1920's, and died in the 1930's. From memory, the only post-WWII Tillotson on an automobile was on Crosley. I posted here hoping someone might know of an antique tractor salvage yard that might have salvage some Cletrac tractors. Jon.
  15. Tractor carburetors wanted

    I know this is a automobile site, but I also know some also play with older tractors. I am trying to buy certain Tillotson carburetors which were used on Cletracs (Cleveland tractor), for parts samples in order to fabricate carburetor rebuilding kits. I would like to purchase Tillotson carburetor cores : S-6A, S-6B, S-6C, ST-3A, Y-2A, Y-2B, Y-7A, YX-1A, YX-1B, YX-2A, YX-2B, YX,3A, YX-3B, YX-4A, YX-7A, YX-8A, YX-10A, YX-11A. I have bills-of-material on all of the above, but need samples, primarily of bowl gaskets, and fuel valves (a.k.a. needles and seats). Cores need not be rebuildable (cracked or even broken castings are acceptable), but do need to be complete. Would really prefer off-condition carbs, as I am going to disassemble for samples, and this will remove this particular carburetor from the pool of available carbs. And do not need all of the above, as many used the same kit, so once I find one of the various applications using a specific kit, do not need the others. If you can help, post in this thread, email, or call 573-392-7378 (9-4 Mon-Tues central time). Jon.
