    I haven't been into one of these for probably 40 years, and I don' t remember.

     

    Only the really hard-core restorers put any of the D series Strombergs back on an engine. The D series was Stromberg's first attempt at a downdraft carburetor, and they used updraft technology. Stromberg freely admitted all of the D series carb had major issues, and when the E series came out, Stromberg issued an E series replacement for ALL original equipment D series carbs. Most of them were replaced in the early 1930's because owners enjoyed driving their cars. On top of that, the D series REQUIRE some special service tools (can be fabricated) to disassemble and assemble (main discharge nozzle requires a special tool).

     

    Here is a link to the original Stromberg literature for the DXC-3 used by Chrysler for only a few months:

    A friend has now fully overhauled the carb, the engine has also now been overhauled so once it's back in the car it'll be fingers crossed how it runs. I guess if it's disappointing I'll be looking for a later carb.

    DXC-3 is one of the few Stromberg 30’s carbs I have not had my hands on. All my books are up north, so I can’t check on them anytime soon. The most important thing is not to guess, Carbking will chime in and give you your answer. Be sure to remove ALL the channel plugs and clean the passageways out. Most of the time they have never been removed, even when rebuilt by “professionals”. Recently at Hershey, one was for sale, and a Chrysler friend bought it, his comment was “they weren’t that great of a carburetor”, having never rebuilt or ran one, I have no opinion. Stromberg stuff of the era was usuall decent to very good. You have a cool car, take your time and dial it in, they run like the wind. Ed

    Cannot answer your specific question, but, attached is some data that may help with your rebuild.

  3. Would anyone have knowledge of removing the sump from a 1931 CD8 281c.i. without removing the engine from  the car?   There appears to be a cross-member at the rear end with a rubber stripped bracket that covers part of the sump, if I remove the bracket will the sump slide back enough to remove? any help appreciated.

  5. Can anyone advise me please!  On overhauling a Stromberg DXC-3 carb. for my 1931 Chrysler CD8 Deluxe convertible coupe I noticed that there is a threaded hole in the base of the fuel bowl which leads into a metering jet. The thread doesn't  appear to have been used so I wonder what should be there (if anything).

    2nd series, 260 cu. in. engine, 4.1:1.

    Thank you for the information, I am in the process of buying this CD8 and wanted to find out what comfortable cruising speed I can expect. Since posting I see that I didn't mention it was a convertible which possibly has a slightly higher ratio, also I now have the engine number from which I have found it is the 282cu.i.  model with 4 speed box. Regards Vic

  7. I have a '31 Buick 8 L90 with an incorrect model Marvel updraft carburettor fitted, after hours spent checking and adjusting I just can't get the engine to run smoothly (running too rich). Also with gas at around 7 dollars a gallon in the UK I want to flip the manifold and fit a more economical downdraft.

    Can anyone advise me what carburettor would work?

    Would I bolt it direct to the manifold and dispense with the heat riser? as I can't think it would otherwise clear under the hood.

    Any helpful advice would be much appreciated.
