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

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

Wikipedia has a good short article on "pot metal". I had a metalurgist test for content on some of the early stuff used on Stromberg carburetors. He commented that the test material contained more than 3 times the lead as more modern (and stable) pot metal, and it was his belief that impurities in the lead caused much of our grief as far as cracking, etc. Stromberg seems to have changed the mixture around 1931~1932, with the later material being much more durable. Different companies solved the issue (or not) at different times. Jon

Hans - you might try posting this question at: forums.maxperformanceinc.com/forums/ Jon

Allen - the limited information I have: Chrysler model L (Imperial) 6 cylinder marine 125 HP engine 289 CID began production with a Holley carb in 1927. The carburetor was a Holley type DD-5BR, Chrysler part number E-6964-M. That is all I have on this engine. Jon

Found the 4A2 and 4A3 in my inventory; thought I had them but could not find them until today. Updated list: Numbered 257s, 262s, 586s, 638s, 640s, 641s, 2035s, 2212s, 3377s, 4403s Coded 4A1, 6A1, 6B1, 6B2, 6C1, 6C2, 6D1R, 6F1, 6J2, 6J3, 6K2, 6K3, 6N1, BB1D Jon

Here is the beginning of the Carter BB-1 updraft carburetor article. There is much data to still be added, as well as pictures of each of the carburetors, but it takes an old geezer time to do things Still looking for several of the carbs. Carter type BB-1 updraft carburetor article Data, as acquired, will be added to the article. Jon

Updated list: Numbered 257s, 262s, 586s, 638s, 640s, 641s, 2035s, 2212s, 3377s, 4403s Coded 4A1, 4A2, 4A3, 6A1, 6B1, 6B2, 6C1, 6C2, 6D1R, 6F1, 6J2, 6J3, 6K2, 6K3, 6N1, 6N2, BB1D Have all of the Chevrolet models, including variations, and most of the universals; but the early Pymouth, DeSoto, Chrysler, Dodge truck and marine carbs seem to be hiding. Original tags are mandatory; condition is less important. As long as the original tag is present, and the carburetor is complete, I am interested. After 60 plus years of doing so, pretty good at disassembling what many would call junk. Need one of each of the above, please help if you can. Here is the link to the beginnings of the article. There is still a lot of data to be added (ie casting number once I get them apart), plus pictures of each carb as I acquire the carb, and have the time (and the weather cooperates!) to disassemble, clean, and picture: Carter type BB-1 article Jon

The Whippet 4 in 1927 did use a Tillotson type S-4B carburetor. The S-4B was zinc alloy, and cracked into many pieces, in some cases, so many they were called dust. It may have been the cause of the engine fire. I doubt seriously if there is a useable original S-4B left in our solar system. Carter listed the BB-1 number 245s as being a replacement for the 1928~1930 Whippet, but there was no listing for the 1927. Checking Tillotson data, the 1928 used a type S-4C. Further checking, the type S-4B and S-4C have different throttle levers. If I were you, and had a BB-1 245s, I would be found trying to get it to fit. Jon

Well, they didn't load in the order I had them??? From the top is page 28, 27, 24, 25, 26. Read them in that order. I need a course in displaying data on this site! Almost like my relationship with Holley carburetors. I have had customers open the hood to show me their engine with a shiny new Holley; and when the Holley sees me, it leaks all over the driveway! Jon

Hugh - I went back over ALL of my Schebler catalogues. All of them list the H as a motorcycle carburetor; however, if one reads the customer list of the 1908 catalog, one finds an entry for Metz - 1 inch model H. There is no mention of the identification number, which I would like to have, if you have it. Here is some information (which you may already have) on the Model H from the 1908 catalog. The checkered background is due to having convert PDF files to JPEG for this site. Virtually all of my 100 plug gigs of carb data are stored as PDF files Jon.

Hugh - if not too much trouble, I would like to have the identification number on the model H for my records. Somewhere there should be a stamping in the casting (generally on top) "HXnn) where nn is a number. Thanks in advance. Jon

Updated list: Numbered 257s, 262s, 289s, 586s, 638s, 640s, 641s, 2035s, 2212s, 3377s, 4403s Coded 4A1, 4A2, 4A3, 6A1, 6B1, 6B2, 6C1, 6C2, 6D1R, 6F1, 6J2, 6J3, 6K2, 6K3, 6N1, 6N2, BB1D Need one of each of the above, please help if you can. Jon

Ramair - thank you! A loan, however, wouldn't work, as I plan on a complete cosmetic and mechanical restoration of each unit prior to the pictures. This is part of my requirement that the original tag be present on any carbs I acquire. I can identify the carbs without the tags, and I have written authority from Carter to reproduce the tags; but it would be somewhat costly. Here is a link to a similar article I did on W-1 Carters for Chevrolet a few years ago: Carter W-1's for Chevrolet I intended to do just the Chevrolet BB-1's, and then decided to expand my efforts. I now have at least one of all of the BB-1's used by Chevrolet, and most of the universal aftermarket units, including the very rare, but not very desirable BB-1 Special that is seldom seen. The Chrysler units seem a little more difficult to find, but I have a couple of them as well. I have enough to start my article when the weather warms, and I can add to it as I acquire other units. I will start with the Chevrolet units, and when they are done, the unfinished article will be posted on my website, and then amended when possible. Jon

Nothing in my files about the Federal Zephyr carburetor; but there is a reference on the internet that George A. Breeze was a consulting engineer for the Federal Brass Works. Jon

Found a 489s and the super rare, but not overly desirable BB-1 Special. Updated list: Numbered 257s, 262s, 289s, 586s, 638s, 640s, 641s, 2035s, 2212s, 3377s, 4403s Coded 4A1, 4A2, 4A3, 6A1, 6B1, 6B2, 6C1, 6C2, 6D1R, 6F1, 6J2, 6J3, 6K2, 6K3, 6N1, 6N2, BB1D Need one of each of the above, please help if you can. EDIT: Removed 289sd from the list Jon

Frank - number 1 was putting an electric choke on my wife's car (a 1970 with automatic transmission) because I didn't (at least I thought I didn't) have time to fix the heat source for the hot air choke. Number 2 was thinking I was a smart enough enthusiast to modify a Pontiac TransAm with a 301 to run as well as a 1969 Toyota Corona 4 cylinder! Both are long stories. Both were lessons. The short versions: (1) My wife informed me she didn't like walking home! (2) Before modifications the Toyota could spot the TransAm 1st and 2nd gears; after a complete engine overhaul and a factory turbo was added to the 301, the Toyota could still spot the TransAm 1st gear. Jon

Shucks, I must be getting old. 1928 Pontiac instead of my guess of 1929. Jon

As previously stated, numbers on side will positively identify, guessing 1929 Pontiac or Oakland. Jon

Looks like an early glass bowl Stromberg. Picture is insufficiently clear to say exactly which one. Stromberg made models A, B, C, D, E, G, and H with glass bowls. Jon

Started working on cars in 1959. The blocked cross-over was one of the top 3 of dumbest mistakes I have made in that time working on my own cars. Thinking about it, it would be number 3. Jon

Late to this thread, and seems the OP has it figured out. In the FWIW category, some 30 years ago, I listened to the internet and blocked the heat passages on a Pontiac. Took awhile to finish the engine (lots of folks wanted carbs rebuilt ) . When I finally got it together, and started driving it, was quite disgusted with performance in town for the first 30 MINUTES! It stalled at every stop sign or light, even with the ambient above 80 degrees. It did start fairly easily. Changing the carburetor to one with a MANUAL choke was easier than changing the intake; and it solved the problem. And no, I WOULD NEVER BLOCK THE CROSSOVER ON A STREET DRIVEN VEHICLE AGAIN! Jon

I have the carburetor, no help on the heat riser. 573-392-7378 (9-12, 1-4 Mon-Tues central time). Jon

My wanted ads for these carburetors are doing nothing! I have added 3 more to the 11 different I had, making 14 different, but I found these on a bottom shelf in my own inventory. Since I have custody of many of the remaining Carter files, empirical research is relatively easy. But I NEED physical carburetors to take my research to the next level. Below is a table comparing the sizes, both S.A.E. flange size, and internal venturi sizes of all of the BB-1 carbs. Please note the largest internal venturi is 1.1875 ( 1 3/16 ) inch. These were primarily used on the Chevrolet 235 CID stovebolt 6. The 2075s will flow the most of any of the BB-1's. It has the same internal venturi as the 871s series (used on the Chevy 235), however the internal portion of the throttle body was tapered, giving somewhat more flow. The 2075s was used on the Chevrolet 261 engine. The Carter BB-1 is a good carburetor, hundreds, perhaps thousands of enthusiasts have proved this; but a carburetor that originally was used on a 261 CID is not going to work well on a 500 CID engine! And while it may work on a 285 CID, probably not as well as a Stromberg or Zenith with the correct air flow. I NEED CARBS! The list needed is in my "wanted" ad. Condition is relatively unimportant, as long as the carb is complete, and the original tag is in good shape. After 50 years of fixing junk sent to me, I am pretty good about fixing junk! So, throwing our some bait Jon
