    Difference between a Carter 1 barrel D6A2 / D6A1 Carb?

    Does it tell you the model Plymouth that used it?  That might be the key in determining the difference.

    Carbking said the idle gets fast if the throttle is not held in place with the linkage and spring.  Looks like you proved him correct!

    I really need to thank Terry  and the others for working with me

    I think that the linkage is correctAnd yes CarbKing must be correct as well.

    But the Carb  had to many hands in the soup.

    I am just going to buy one and see if it will do the job.If not then its not the Carb ?

    your thoughts

    Idle is way to high on my 1941 plymouth 1-barrel

    For sure the idle is too high if you do not have to give it any gas to pull out.  Tell me about cold starting, do you pull out the choke first before starting?  When the engine starts with the choke pulled out, does it idle fast?  Does the idle slow down when you push the choke back in?   
     

    I’m still thinking your problem may be with the carb linkage, especially when you say the idle adjustment screw is turned all the way out.  Makes me think something is not connected properly with the choke to carb metal cable or something with the gas pedal linkage.  
     

    Glad to hear you have a shop manual.  That is very important to have when trying to fix problems like this.

    Good observation Grimy!   I missed the throttle knob and yes it’s another good thing to check as you explain above.  

    I have tried everything that everyone has told me to try or do.I do not know if I am doing this correctly or not

    But nothing is working.they tell me it is the carb ? but I have had this carb replaced and kits to the original and no luck

    where can I take this 1941 Plymouth to get it corrected ?

    its the high idol ,and anything over 2500 rpm it will spit and choke ?

    thanks

    thank you

    I bought a service book Plymouth for my 1941 Plymouth

    it has most everything  .I tried to do what you told me top do but it does help lower the idle a bit turned it to 1 1/2  but the other screw is all the way out 

    I still think the idle is to high cause I can pull out and shift without gas and it will go ? will not stall

    is that ok ? as for it choking and trying to stall when flooring the gas pedal it is still there I do think it is the carb

    a friend of a friend has a carb but needs to be  sent out for repair do you know who I can send it to ?

    thank you  once again

    Can you please take a picture of the throttle adjustment screws on your carburetor?  As I said, my pictures are typical and may not be exactly what yours looks like.  A picture of what you have would greatly help.  
     

    Also, do you have a carburetor choke control knob on your dashboard?

     

    Wish I could help in person too!

    and I can not find the fast idle adj. screw 
    looks like there are 2 ?
    the spring near the pedal is there 
    I really need someone who really knows what they are looking for I do not
    here are the pics for you I do not know if this is or are the pics you need 
    I did take pic of the dash you can see the choke and other knobs

    Here are two pictures of a Chrysler design (the rusted throttle body) and a Carter-design as the carburetor sits WITH NO EXTERNAL FORCE APPLIED (picture 1).

     

    Note the Carter throttle valve is closed, and the Chrysler throttle valve is about 1/2 open! You can see the space between the throttle plate and the throttle bore. Under this condition, idle would be about 2000 RPM!

     

    Now look at the second picture, where I have simulated the action of a throttle return spring that would normally be attached to the throttle arm. Now the Chrysler design is closed like the Carter design.

    I am so sorry

    I have no idea as to what you are saying to look at I know nothing about  linkage and carbs.

    was hoping someone could come and work on this  I have had a few people  who tried but ended up making it worse.

    the idol is now to high the linkage i think is wrong, the original linkage that was on this was taken off and so called tossed out

    plus the when the throttle is kicked down it chokes and wants to stall .

    is there anyone in the Ohio W.Vir.  Pa area that can make a house call and make it right ?

    thank you

    The screw with a smallish spring around the threads and located near where the gas pedal linkage is attached to the carburetor is an idle speed adjustment.  The other spring discussed is a much larger spring that is used to put tension on the gas pedal linkage to make sure the gas pedal returns when you lift your foot from the gas pedal. The big spring keeps the throttle linkage in tension so it closes the throttle.  That big spring needs to be doing it’s job so that you can make idle speed adjustments with the small screw.

    I Am so sorry I  have no idea as to what you are saying to me 

    this is why I was hoping that there is someone in my area to come and figure this out

    LOOKING For a Carter 1- barrel Carb. Ball & Ball D6A2 fully restored  


    or someone in the Pgh. Pa. area that can restore the one I have

    this is what also needs to be looked at or done

     

     might be problem with fuel flow from the main metering screw in the carburetor float bowl and possibly the main discharge jet since that is the area A mechanic was most likely messing with.  ed.  You or someone you know will have to look at the carb to see what the last mechanic changed to make the car run leaner in his attempt to eliminate the black smoke.  If the main jet circuit (circuit is the name given to sections of the carburetor) has a problem it will affect the running of the engine like you are describing.  

    why is my 1- Barrel carb. leaking and flooding out ?

    Hello

    when I give the car some gas it goes great but when I ask it for all of it it will sputter , spit, chock and I have to let off the gas and drive it where it will accept the normal 

    why is this .it was running great until this mech. was going to mess with the carb. cause it was running to rich and black smoke out the pipe.

    from he touching it  .It never ran right again.I asked him what he did he said he just placed different jets in the carb. I told him to place it back the way it was I can handle black smoke . but he moved on and passed never did finish this What Mech can take this 1 bar. carter carb and make it correct.

    Who do we trust

    Johnny,

    I found this from you on another thread you have.  You also said you have a new carburetor installed.  Your post indicates the mechanic changed the jets to make the carb run leaner and that’s when the trouble started. To me it seems like there might be problem with fuel flow from the main metering screw in the carburetor float bowl and possibly the main discharge jet since that is the area your mechanic was most likely messing with.  Look at the diagram I’ve attached.  You or someone you know will have to look at the carb to see what the last mechanic changed to make the car run leaner in his attempt to eliminate the black smoke.  If the main jet circuit (circuit is the name given to sections of the carburetor) has a problem it will affect the running of the engine like you are describing.  There are carburetor data sheets similar to the photo I’ve attached that you can buy to help you too. Perhaps carbking has these?

    Hope this helps.

    Forgot to mention- good news on the needle correction!

     

    Here is a YouTube video that shows where the main jet is in the carb float bowl.  Actually it shows the reassembly of a Carter carb similar to yours.

     

    thank you
