  1. And just to follow up on my comment about a "new" carburetor: To make one of the e-clones work properly on a Buick engine (at least for awhile), one would need to change: primary jets, step-up piston springs, step-up rods, secondary jets, and auxiliary air valve; AND re-machine primary venturii clusters and secondary venturii clusters. And the original air cleaner still would not fit, plus there are linkage issues. Jon.
  2. To MAYBE answer your question: If you TRUST the aftermarket (Motors, Chiltons, etc.) manuals: 1964 Riv with single 4 barrel times at 2 1/2 BTDC 1964 Riv with 2x4 times at 12 BTDC I don't have the factory manual, and I don't put a lot of trust in the aftermarket ones. Jon.
  3. Suggestions: (1) shop manual - ignore (2) through (4) until you have this one in hand. then (2) compression test (3) ignition test (4) carburetor test (you said new - does that mean new to you original, or new as replacement as in one size fits all, works well on none?) Find out WHY the engine was running poorly, solve that issue to get the engine running correctly; then if your want to downgrade from the carb to the efi, go for it. Good luck, and please keep us posted. Jon.
  4. Probably not a leak: Jon.
  5. Have had a few inquiries as to why I didn't just make copies. While I tried to explain this in the original post, someone once said a picture is worth a 1000 words. So, here is a photocopy of an original page for GMC: Stromberg code book original page And here is a copy of what we now have: Stromberg Code Book new printing Jon
  6. Shirley - THANK YOU for posting! I am always interested in the men behind the carburetor history, but my main focus is the original drawings (or copies) of the carburetors and their parts. Pages from illustrated parts books with listings by part numbers are the most prized, but any technical data is helpful. Again, thanks for posting. Jon.
  7. After years of transcribing, I now have the complete Stromberg Code Book digitized, and able to print "readable" information. While "readable" in quotations? The original code book (I have the original single copy, and a photocopy I did for off-site backup 40 years ago) was mostly typed, but on lined paper, and the typewritten information didn't always square with the lines. Additionally, most later entries were hand-written in red pencil, which over a period of 60-80 years has faded. The code book contains an index of carburetors produced for specific companies, both original and aftermarket replacement, from roughly 1925 (some earlier) to 1974 (last production Stromberg carburetor). There are no calibration specifications, but I can provide those at additional cost for a large majority of the carburetors listed. This book is one of my main reference guides when choosing a replacement carburetor to replace original carbs which are either simply no longer available, or extremely pricey. These carbs were selected and calibrated by engineers for specific applications. I will print and mail these 8 1/2 by 11 laser printed copies at $20./company or $50./3 companies or $100/7 companies. Above 7 companies $12./company. A list of companies and the associated Stromberg code number follows: Jon. Stromberg Code Customer Index Customer name Code number A. C.

  8. Obviously - a man who has been on a Snipe hunt, in this case a Super Snipe. Jon.
  9. Have you ever been on a Snipe Hunt? Jon
  10. Brian - no longer restore carbs due to the demand for the rebuilding kits we make, but give me a call 573-392-7378 (9-4 Mon-Tues central time) and will offer, if you wish, some pointers on the tube and the carb. That Rochester, or the original Carter 4-barrel, Pontiac used both, are great carbs. Jon.
  11. There was originally a steel tube pressed into the exhaust port of the intake manifold, more or less horizontally, which connected to a small chamber on the passenger side. A steel tube then connected this chamber to the choke housing on the carburetor. There is a small internal vacuum passage inside the carburetor has causes the choke housing to have a slight vacuum. This vacuum then causes heated air to be drawn through the tube to operate the choke. To slow the heated air, there was originally a twisted piece of metal, similar to an ancient piece of barb wire without the barb. You can see a piece of the original twisted metal in your picture. The manifold may be heated, and the old steel tube driven out, and replaced with a new steel tube. When we were restoring tripower manifolds, we used stainless, but no longer have any inventory of the stainless. Plain steel normally is good for maybe 30 years. The twisted tube may be fabricated from a piece of flat steel. Don't know if the parts are available reproduction, as they are so easy to fabricate, but you might try Kelsey Pontiac Parts in Iowa Falls, Iowa. Jon.
  12. These numbers cannot easily (if at all) be decoded. They are casting numbers for "blank" castings, prior to the casting being machined. The best example I can give would be throttle bodies from Rochester 2-barrel carburetors for 1957 Pontiac tripower. Front - no idle screws, 1/8 inch pipe vacuum port Center - idle screws, 1/8 inch pipe vacuum port Rear - idle screws, no vacuum port ALL have the same casting number. I am unaware of any EX-32 other than the supercharged Auburn that use 1 3/8 venturii. However I have not checked the prints on all of the EX-32's. Jon.
  13. I generally use steel, as I have the tools to work it. Historically: aluminum, brass, copper, and steel have all been used; and copper a LOT later than some would think. Oldsmobile was still using copper in 1966 on their performance models. Jon.
  14. Not until you do the compression test, and find that all cylinders serviced by the side of the carburetor with the unresponsive screw have decent compression. This comment from the guy that makes and sells carburetor repair kits! Jon.
  15. Curti - not a "one size fits all" answer. Referring to USA-built Strombergs: Many have the internal venturi size cast into the bowl casting. Some have the main metering jet I.D. stamped into the casting. Most will have the part number for the BLANK CASTING cast into the casting. This is not a part number most will find anywhere. It is an internal number for a casting prior to machining. Beginning about 1935, Stromberg stamped the "code identification number" of the carburetor into one of the castings. From my website: "Stromberg The following applies to Stromberg-USA carburetors, and does not apply to Stromberg carburetors produced elsewhere: Stromberg began stamping a ‘code’ number on virtually all O.E. (original equipment) carburetors beginning in 1935 up through the end of production in 1974. Most of the carburetors produced in the late 1930’s were stamped on the throttle body. Others were stamped on the airhorn. After 1940 this trend was reversed, and most carburetors were stamped on the top surface of the airhorn along one of the edges. Replacement carburetors produced during this period were generally identified by tag only (although a few replacements were stamped). The stamped ‘code’ is in the format ‘ccc-nnne’ where ccc is a one, two, or three digit code representing the company for which the carburetor was produced (ie 2=Ford, 4=Chrysler, 7=Buick, etc.); nnn is a one, two, or three digit number representing the next sequential number of carburetor sold to the company in ‘ccc’; and e is a letter (if present) representing the engineering change status of the carburetor. An example would be 7-69A which is decoded as 7 (Buick); 69 (the sixty-ninth type of carburetor sold to Buick – this one fits a 40 series in 1949); and ‘A’ meaning one engineering change to the original specifications. A second change would be 7-69B. Stromberg used both rectangular (held in place by a screw) and round (riveted in place) tags during this period, on those units which were tagged. Stromberg carburetors produced prior to 1935 can easily be identified as to type, as it is cast onto the carburetor; however complete identification is impossible unless one has prior knowledge of the carburetor being identified; and can be quite difficult and time consuming for even someone with the original prints." Jon.
  16. Read down to the paragraph on "Testing": Jon.
  17. From the "troubleshooting" section of our website: HARD STARTING, COLD Difficult starting a vehicle that has been allowed to sit for a number of days (that will then start well the rest of the day) is often caused by modern fuel. Modern fuel begins to vaporize (evaporate) at a much lower temperature than fuel before the 1970’s. Once the engine is shut off, the fuel in the carburetor bowl begins to evaporate through the bowl vent. If there is no fuel in the carburetor, the engine will not start. Pumping the footfeed during this time simply prolongs the agony, as the accelerator pump will pump the fuel into the engine, but in amounts insufficient for starting. If you have this problem, try priming the carburetor by using an eyedropper and filling the carburetor bowl through the bowl vent prior to cranking the engine. If you do not wish to prime the engine, crank the engine for 15 to 20 seconds WITHOUT PUMPING. Then stop cranking, pump the footfeed 3 or 4 times, release it, and then reattempt to start the engine. Priming eliminates excessive wear on the starter. Another possible solution is the installation of an electric fuel pump. If an electric pump is installed, check local, state, and federal laws about wiring; and pick a pump with pressure not exceeding that of the original pump. Jon.
  18. Unless the automatic transmission is also changed to a late model transmission, I would suggest the original hot air choke is head and shoulders above the electric. If one installs an electric choke on a pre-mid-1970's vehicle with the original AUTOMATIC transmission, then my advice would be either: (A) After starting the vehicle in the morning, allow it to idle while you go back inside and drive TWO cups of coffee SLOWLY OR (B) Subscribe to Triple A I learned this lesson the hard way maybe 35 years ago. I was too busy to replace the heat tube on my wife's car, so installed the electric choke. She would start the car, drive it three blocks to a stop sign, the engine stalled AND WOULD NOT RESTART! This happened twice, and she informed me either fix it or buy me a new car! The issue is the choke would be wide open after 45 seconds but the engine would not run at idle (driving kicked off the fast idle cam), and with the choke wide open she was unable to start the engine on cooler (mid 50's) days. Spent the next week-end fixing the hot air choke, and she again loved the car! Of course, one can always block traffic at the stop sign/light for about 20 minutes allowing the choke coil to re-close. Jon.
  19. Well - the Bendix-Technico kind of removes me from helping with this carburetor. I simply do not have the resources. However: Bendix Aviation was/is a conglomerate. Until they were partially disassembled by the anti-trust do-gooders, Bendix Aviation was the parent company of both Stromberg Carburetors and Zenith Carburetors. Think of the relationship that Bendix is to Stromberg as G.M. is to Buick. And while both Stromberg and Zenith DID build aviation carburetors, the ground division of both Stromberg and Zenith was much larger than the aviation division. Do not get side-tracked by the "aviation" in the Bendix name. Stromberg had "sister companies" in other parts of our world from the USA. Bendix-Technico is the sister company of Stromberg in Australia. I am the current caretaker of the remaining Stromberg-USA drawings, manuals, etc. but I have virtually NOTHING on Bendix-Technico. On USA-built B-series Strombergs with the externally adjustable main metering jet, the operational range of the adjustment was from zero to 5 turns. The suggested starting calibration was 2 1/2 turns and then tune from there ASSUMING THE CARBURETOR INTERNALLY IS CORRECT FOR THE ENGINE. Since you have this carb, I would suggest trying to adjust this calibration, to see if you can improve performance. Zero turns is very lean, 5 turns is maximum fuel richness. Maybe someone else has more information than I on Bendix-Technico. If it turns out you wish to change carburetors, it will obviously depend on what is readily available in your area without paying large shipping charges. If the vehicle were in the USA, AND the owner did not require a "period" carburetor (one from the early 1930's), I would suggest a Carter type YF used on a 300 CID Ford 6. Excellent carburetor, and common as dirt. Jon.
  20. I knew I should not have guessed! The pictured carburetor is a Stromberg B series DOWNDRAFT. The original Marvel on a 1930 Buick 40 would have been an UPDRAFT, as is the Stromberg SF series. So, either the engine is from a later Buick, OR, more likely, someone has flipped the intake to junk the "marvelous" Marvel, and replace it with a real carburetor, in this case a downdraft. So the first order of business would be to determine the year and size of the engine; either verifying that it is the original with a flipped manifold or ??? The B series Stromberg is also an excellent carburetor IF this particular one is suitable size-wise to the engine. No need to speculate further until the origin of the engine is known. However knowing the fraction in a circle on the bowl (center) casting will help us determine if the carb is applicable once we know the engine origin. The fraction should be something like 1 3/32 or 1 5/16 or something similar. This is the I.D. of the main venturi, and is the main consideration in adapting a non-original carb to an engine. Also need to know if this carb has the external adjustable main jet (would be a turnable knob pointed up at a 45 degree angle on the edge/bottom of the bowl (center) casting. I cannot tell from the picture. Or, take pictures of the carb from all 4 sides. Jon.
  21. F.H. Ball is probably Franklin Harvey Ball. The son is mentioned in different references as F.A.Ball or F.O. Ball. I have no other information on the son. Jon.
  22. This link explains the Stromberg type SF carb, and there are pictures that will help you with the identification. Jon
  23. I would like to clarify something that was posted to which I have no proof: Carter DID purchase the rights to use the Ball and Ball designs. Ball and Ball were a father and son, not the "Ball Brothers" as I have seen elsewhere or "pump design using two ball bearings" as I have also seen. Carter started producing the Ball and Ball updraft carburetor in 1932 (I have complete access to the Carter carburetor applications from about 1920 forward). This includes experimental, production, racing, and those that samples were sent for approval to the customer, rejected, and cancelled. Ball and Ball carburetors WERE used on a number of Chrysler applications prior to 1932. HOWEVER, I HAVE NO RECORD THAT THE MODEL PRODUCED BY CARTER WAS EVER USED BY BALL AND BALL. Not saying it did not happen, but I have no proof. The Chrysler model 72 used the Penberthy Ball & Ball (Penberthy was the manufacturer of the Ball & Ball designs prior to Carter) model SV-37. The Chrysler model 75 used the Penberthy model DB-20. The Chrysler model 50 used a Penberthy model S-1. All were zinc alloy carburetors, resembled the Carter versions only in that all are updraft, and like most zinc alloy of the time, have cracked into dust. In 50 years of playing with carbs, I have yet to see a serviceable S-1, SV-37, or even a complete DB-20. The Chrysler model 70 used a Penberthy model SV-26. Memory fails, but I think a combination of brass and zinc alloy. Again, NONE of these models resemble the Carter BB updraft. I have examples of all the these Penberthys, but they are useful only for parts if someone wanted to cast new castings. None of them are serviceable using the original castings. The Chrysler model 65, according to my records, used a Stromberg type U-2. Stromberg actually made three different models of the U-2 in dozens of variations. The three different models were: zinc alloy with no economizer, zinc alloy with economizer (Chrysler used this one), and cast iron (primarily used by Franklin). The good news is the type used by the Chrysler 65 is being reproduced in Australia, IF someone wishes to maintain the vehicle as close to original as possible. Jon.
  24. Stromberg made some of the finest carburetors ever made, anywhere, at any price. That doesn't prevent someone from pulling one from under the workbench that is incorrect for the vehicle, or the carburetor being incorrectly set up for the vehicle in question. Exactly which Stromberg are you dealing with? What type of fuel delivery system? If pressure, how much pressure? Where is the backfire? Through the carburetor, or through the exhaust? And GUESSING (never a good idea, but I do it anyway): If you have one of the SF series Stromberg carbs, the SF series use an inverse idle circuit. Adjusting "IN" makes the mixture richer, "OUT" makes the mixture leaner. If the screw is completely closed, that would be the richest idle setting. The high speed adjustment (if present), is the conventional in lean, out rich. The suggested initial setting was 2 1/2 complete turns from lightly seated. IF YOU HAVE ANY OTHER STROMBERG THAN AN SF SERIES, DISREGARD THE ABOVE! And you mention having done everything else, but you suspect fuel starvation. No offense intended, but valves which are too tight will mimic this symptom, as will a defective electronic distributor conversion. In fact, if an electronic conversion is done, ALWAYS the first test is to UPGRADE back to points/condenser. Jon.
