RE: {Chrysler 300} carb work

Drew, as someone who has used a 1947 Desoto as my daily driver for 22 years, the “new” 300K is going to replace that duty, I have extensive experience with the Carter BB carb.

Jon at The Carburetor shop should have new shafts and butterfly valves and everything else you may need. BUT HERE IS THE PROBLEM.

Even if you rebuild everything you can still get a bad running carburetor. Why? Because Carter used emulsion tubes inside the body passages. The lead gas over time causes these to start to fall apart. You need a special tool and new tubes to replace these. Jon may or may not have what you need. I fought like hell after rebuilding three carbs top to bottom including new shafts and it still idled like crap on all three BB carbs.

Then luck. I ran across a NOS carb. Cost a lot, but I cleaned it and put in new gaskets and fired it up. Runs like a dream and has for 15 years. Unleaded gas will not “sandblast” the emulsion tubes.

You can get a good machine ship to drill out and bush the body and rebuild it with new parts save the emulsion tubes and see how it does. You may get lucky.

Subject: {Chrysler 300} carb work

First I want to say thank you to everyone who answers my many questions. I don’t have a lot to offer since I am relatively young and inexperienced compared to the majority of the group. Next I want to apologize in advance for asking a non 300 question but I think there will be some good insight so I am going to ask. I have a 1937 Plymouth I have been working on lately. Inline 6 very common Mopar engine. The carburetor is very worn. The linkages all leak where they pivot. Are there any reputable shops that can redo a carb like this? Maybe drill the body out and install bushings in these areas? I can do the basic rebuild but the machine work I cannot do myself. Thanks in advance for any help.
