    Carter problem

     



    Ok, My brother just switched to a '66 carter 4-barrel on his '66 Catalina 389 and it has a flat spot under light acceleration. Someone had said it might be the accelerator pump but I don't think so because you can hold it at the point where it stutters and it will keep stuttering. I tried putting new jets (edelbrock #1426 .095 orifice) in it and forgot to put the rods in and it ran good but when I put the rods (edelbrock #1455 7042) in it was back to stuttering. The step-up springs are edelbrock silver 8-in. Hg.

    Yeah, I had already been there. But the kit that I had bought only had 3 rods 3 jets and 4 step-up springs so I'm trying to get an idea of what range of rods & jets I need to get

    Good luck....

    You had it running good, why not go back to that setup?

    Because I had forgot to put the rods in it, so it wasn't really tuned right. Then I tried to take the rods out again a few hours later and it ran really bad.

    The choke was open and the vacuum is good. When I tried running it the second time it ran really rough but not at first so I think what happend was that we just started it and immediatly started testing it so it didn't have time to start missing.

    It's been a few years since I last worked on a Carter, but if I'm not misstaken the metering rods primary purpose is to restrict fuel through the primary jets at idle. To me that would indicate that your primary jets are too small or the metering rods are too big. If the motor has a healthy cam it will add to your problems.

    Tech, as usual is right on the money. The manual explains it all.

    It was rebuilt about 4 months ago and was being painted for 3 so it didn't run much. It is a 625cfm

    Gerig, if you'll do what I suggested you do in the first place, your problem will be solved. Go to the owner's manual and read "Calibrating the power mode staging". It describes exactly the problem you're having and the fix for it.
    I have already read the manual and that is not what I'm looking for, I have already changed the springs and that didn't help, it just says that it could be a metering problem but I already know that. I'm pretty sure I need to lean it out because the idle mixture screws don't work but I don't know how many stages back I need to go and I want to get an idea before I go out and buy more jets and rods that won't work

    If I could I would but he just got it painted (which reminds me. I'll post pics. in another post) and we haven't gathered anything to sell as I'm 16 and haven't had time to really get a collection of parts and we have moved twice in the last 10 months so I have already had to get rid of stuff that I had gotten.
