dl456 Posted August 20, 2018 Share Posted August 20, 2018 Hello, Looking for the model number of the B&B carb. used on the Studebaker Big Six for 1920 so I can start my search. Please let me know what to look for or if you know where one exists. Thanks, Dennis Link to comment Share on other sites More sharing options...
carbking Posted August 20, 2018 Share Posted August 20, 2018 If you find out, please post, as I would like the information for my records. In the meantime, Stromberg released a model LS-2 for the 1919~1924 Big Six. It was calibrated with a 1.125 inch venturi. (Opinion) the very worst Stromberg is greatly superior to the very best Penberthy. Jon. Link to comment Share on other sites More sharing options...
dl456 Posted August 20, 2018 Author Share Posted August 20, 2018 Hello Jon, I have a LS-2 on my Special six (288 CI) and I have an extra. I assumed the big six (354 CI) would need something in the range of 1.75" venturi. I would like to hear your thoughts on recommended throat size and best carb. for touring. Thanks, Dennis Link to comment Share on other sites More sharing options...
carbking Posted August 20, 2018 Share Posted August 20, 2018 Dennis - the Special Six used a smaller internal venturi. I am a firm believer that one should pay attention to the engineers. And the Stromberg engineers recommended the LS-2 with the 1 1/8 inch venturi for the Big Six. The Penberthy would probably need to be much larger, as they were not overly efficient. Jon.

George Rohrbach Posted August 21, 2018 Share Posted August 21, 2018 My list has it as a LS2 Penberthy, for the Big Six. Link to comment Share on other sites More sharing options...
STUDE48 Posted August 21, 2018 Share Posted August 21, 2018 The parts book list the ls2 stromberg for only eh (special six)models from 20 to 22 and the ball and ball for the eg(big six) in the same years. Owners and shop manuals confirm the same. If you need it I also have the adjustment and repair procedures for both carbs Link to comment Share on other sites More sharing options...
STUDE48 Posted August 21, 2018 Share Posted August 21, 2018 The dukes auto encyclopedia calls out the model of the ball and ball as an sv-29 in the adjustment procedure Link to comment Share on other sites More sharing options...
dl456 Posted August 21, 2018 Author Share Posted August 21, 2018 Thanks for the comments. My manual says the same. Listing the model of the Stromberg as LS-2 for the EH but omitting the model of the Penberthy for the big six. Anybody have a SV-29 to measure the throat size? Jon, What are your major issues with the Penberthy? Can you recommend a good replacement? I like to keep things original but will make some compromises for reliability and performance. I have a Rayfield running good on my Mitchell after considerable tweeking. Not an impressive or easy to understand carb. Dennis Link to comment Share on other sites More sharing options...
carbking Posted August 21, 2018 Share Posted August 21, 2018 (edited) Factory equipment for the Big Six (as far back as I have material): 1923 Penberthy (Ball & Ball) SV-12 1924 Penberthy (Ball & Ball) SV-12 1925 (early production) Penberthy (Ball & Ball) SV-14 1925 (late production) Penberthy (Ball & Ball) SV-29 Factory SERVICE carburetor 1923 Penberthy (Ball & Ball) SV-29 1924 Penberthy (Ball & Ball) SV-29 1925 (early production) Penberthy (Ball & Ball) SV-29 AFTERMARKET carburetor recommendation by Stromberg: 1919~1924 LS-2 with 1 1/8 main venturi. Think of the physical designation of a carburetor model the way you would a tire. 15 inch tire 165-75R15 (Volkswagen Beetle) 235-75R15 (Ford 1/2 ton truck) other Stromberg LS-2 carburetor 1 1/32 inch venturi - Studebaker Special Six 1 1/8 inch venturi - Studebaker Big Six EDIT: this link for a different model of Stromberg should further explain external/internal carburetor sizes: http://www.thecarburetorshop.com/Stromberg_SF_carburetors.htm And to your final question: Quote Dennis: "Jon, What are your major issues with the Penberthy? Can you recommend a good replacement? I like to keep things original but will make some compromises for reliability and performance. I have a Rayfield running good on my Mitchell after considerable tweeking. Not an impressive or easy to understand carb." End quote I once hauled in a pasture of hay using a Toyota pickup, and it got the job done. The next cutting, we used a Ford 2-ton flatbed. It also got the job done.......................better I made the comment about the aftermarket LS-2 as my professional opinion is that the Strombergs WERE better carbs than the Ball & Ball design (even Carter couldn't make the Ball & Ball design work well after they bought the rights to the design!). Plus, in 51 years I have been unable to find ANY information on the early (pre-1923) Ball & Ball Studebaker carbs, and so far, no one has posted any in this thread; and there are at least some new parts available for the Strombergs, as far as I am aware, nothing for the Ball & Ball units.

dl456 Posted August 21, 2018 Author Share Posted August 21, 2018 Jon, Thanks for the reply. I am digesting this info. and pretty sure I get it. The comment about tires and the link puts things in a clear perspective. Dennis PS: We were lucky enough to bail for a farmer that bought a large implement trailer about 12 inches off the ground. You could stack 5 high (155 bales) and barely break a sweat. Better than a Toyota or a Ford. Those were the days! Link to comment Share on other sites More sharing options...

dl456 Posted August 27, 2018 Author Share Posted August 27, 2018 Thanks Ken, Pictures would be great. I had the car running fair yesterday. Not ready for prime time. It has an adaptor and a Carter B&B on it now. Throttle linkage from the steering sector is missing and the carb. is sitting at on odd angle making it near impossible to hook things up correctly. I also need a distributor cap and rotor for Remy 358-A . Any suggestions? Thanks, Dennis Link to comment Share on other sites More sharing options...
1927Chevy Posted August 27, 2018 Share Posted August 27, 2018 Dennis will post pics this weekend also have info on 1923 big six cap and rotor there, at work during week back to car this weekend. Ken Link to comment Share on other sites More sharing options...
STUDE48 Posted August 29, 2018 Share Posted August 29, 2018 Here is a picture of the linkage from the studebaker parts book 3 series 19 thru 22. I hope it helps. I found it helpful when I was sorting mine out. Link to comment Share on other sites More sharing options...
