cricketkj26 Posted April 4, 2018 Share Posted April 4, 2018 Can one of you folks advise what the correct carb is suppose to be on a 218CID G70 Chrysler? Built in Oct 1925 It has a Dodge Bros Detroit Lubricator on it now. It runs ok but its obviously not correct. Stromberg OS 2 ??

Sasha39 Posted April 4, 2018 Share Posted April 4, 2018 (edited) Looks like they change carbs in mid stream, do you know the Fedco number? It could be a Stromberg, Zenith or a Ball and Ball Here is a G70 with a Zenith carb Edited April 4, 2018 by Sasha39 (see edit history) Link to comment Share on other sites More sharing options...
28 Chrysler Posted April 4, 2018 Share Posted April 4, 2018 Here is the Ball and Ball 1 Link to comment Share on other sites More sharing options...
cricketkj26 Posted April 5, 2018 Author Share Posted April 5, 2018 The Fedco # is WL488H. Is one of the three a better functioning carb assuming they are thouroughly rebuilt correctly and adjusted correctly ? Cricket Link to comment Share on other sites More sharing options...
Sasha39 Posted April 5, 2018 Share Posted April 5, 2018 I would try to find a Cater BB1 245SA for ease of getting parts Link to comment Share on other sites More sharing options...
carbking Posted April 6, 2018 Share Posted April 6, 2018 The three original carbs: Penberthy (Ball & Ball) SV-26 (zero parts availability) Zenith type 105B (zinc alloy, cracked to pieces) Stromberg OX-2 (brass carb, excellent for its day, good parts availability, but parts and/or carb are not cheap). The OX-2 (type O, cross-flange, size 2) is in great demand to replace the later TX-2 (zinc alloy) and UX-2 (zinc alloy) carbs that crack to pieces. The BB-1 is an oft-used replacement carb, but is a straight-flange, so a cross-flange adapter would be necessary, and no offense to Sasha, the BB1A or BB1D would be the correct BB-1 for this application. And as shown in the chart, would require a Carter 72-20 (or equivalent) adapter. Jon. 1 Link to comment Share on other sites More sharing options...

Since we are doing "period" pricing, need to consider "period" finances. Will be happy to sell my new old stock (uncirculated ) 72-20 adapter for $1.00 if it is an uncirculated 1928 U.S. silver dollar! Jon. 1 1 Link to comment Share on other sites More sharing options...

viv w Posted April 6, 2018 Share Posted April 6, 2018 Hi Cricket, my right hand drive model G70 has engine number 101050 and has a block casting date of 7/22/25, the head has casting date 8/25/25. The cars body had long gone by the time I got the rolling chassis, so I don't have a Fedco number. From the number of spring blade leaves I have figured the car was a tourer, and was specially equipped with type 4 Buffalo wire wheels.The car I have, was last run in 1958 and it came to me, with a brass bodied Zenith Detroit SV5B carburettor still bolted to the manifold. I assumed this to be the original carb for my motor, but I stand to be corrected. I will try in the next few days to take a few pictures of the carb and upload them. My carb is nothing like the Zenith carb shown in a picture by Sasha39. Sasha's picture quite clearly shows an adaptor between the carb and manifold. Viv. ps, its interesting that your motor number and mine are only 63 apart and yet my block was cast more than 2 months earlier. Link to comment Share on other sites More sharing options...
viv w Posted April 8, 2018 Share Posted April 8, 2018 Hi Cricket, this is the carb fitted to my RHD G70. Viv. Link to comment Share on other sites More sharing options...
viv w Posted April 8, 2018 Share Posted April 8, 2018 I have downloaded a lot of pictures off the internet and ebay for reference, several of the cars show the carb as attached to the manifold in this picture, the Chrysler 70 owners manual shows a carb as per picture carb 2. The owners handbook also says carb supplied by Penberthy injector company. Hope these pictures help. Viv. Link to comment Share on other sites More sharing options...
Narve N Posted April 12, 2018 Share Posted April 12, 2018 I've got a BB-1 carb that is not a Carter. It is a Ball & Ball "Manufactured for Chrysler Corporation" and looks almost identical to a BB-1D. Is this the correct carb for a Series 75, and somehow Carter later bought the company and shortened the name to BB? Link to comment Share on other sites More sharing options...
carbking Posted April 12, 2018 Share Posted April 12, 2018 (edited) Carter produced the BB-1 carbs. The very earliest BB-1 carbs were manufactured by Carter for Chrysler Corporation (1932). The Penberthy Injector Company produced carburetors for a number of manufacturers from 1916 through 1929. They look nothing like the Carter BB-1. The only resemblance is that both are updraft. The BB-1D is just one model of the type BB-1, and was released after WWII. It replaced the BB-1A. Jon.

Spinneyhill Posted April 12, 2018 Share Posted April 12, 2018 It looks like Carter produced the BB-1 Carb, where BB stands for Ball & Ball. Link to comment Share on other sites More sharing options...

Apologies for the dizzy photo, car is currently at the upholstery shop. Link to comment Share on other sites More sharing options...
cricketkj26 Posted April 25, 2018 Author Share Posted April 25, 2018 Sounds like CarbKing is definately the King of Old Carbs. You Aussies, New Zealanders are always extremely helpful on these old first Chryslers. THanks to all who provided photos and data copies. Great Info! I have a direction to go in now. Cricket Any of you folks from down under know what color the head and block were orignally on these G70 chryslers ? I have looked at every engine photo I can find on the old interweb and no two are the same. The 1925/26 heads were not red heads and my head doesnt say Siverdome on it. Would Silver head and black block or grey block be correct ? Currently the block and head are red with black cover plates. Thanks, Cricket.
