    Stumble issue

    Yep, I cleaned it out. With the car off and manually twisting the throttle it seems to me like it gets a nice shot of fuel and it looks instant. I used a 7/16" drill and just used a 6" rule to measure the drop. I understand that it could be the pump when it bogs off thr line, but what about...

    Stumble issue

    Ok, heres what I tried today. Took top off and checked float specs which are good. Has stock 1411 main and secondary jets in. I do not have the stock metering rods so I tried closest that I have with orange springs. Also checked choke. Works good and opens fully once warm. Next I went to middle...

    Stumble issue

    Have not checked float level. Dont know vacuum. Silver spring in now. (heaviest) I think the metering rods were 6842. Which seems very rich to me. Its in top hole on pump arm. Electric choke. Choke seems to work great. I know I have to to my homework and check float level and vacuum. I just...

    I have the manual. It says that if you have a stumble issue at light throttle to go to the heaviest spring.

    Stumble issue

    I though a heavier spring opens the power mode sooner? I do need to check my fuel pressure. Probably should have been one of the first things to do. I already have a calibration kit. Thanks again guys. I hate to get rid of it, but a lot of people say to get a holley they work good out of the box.

    Stumble issue

    Ok so I hooked the vacuum advance up today and had no change, still stumbles off the line. Checked the accelerator pump and looks good, shoots plenty of fuel. I also thought I would try heavier springs for the metering rods in the eddy carb but when I pulled them out, it already had the heaviest...

    Should the vacuum advance be hooked to ported or non ported?

    Stumble issue

    I was told they were 77 heads and 9.5 to 1 compression but I dont know for sure. Yes I do have the vacuum advance plugged. I will try to back the timing down and see what happens. Thanks for the help guys!

    Stumble issue

    I have a 69 Dart with a 1972 440 in it. My issue is that it has a bad stumble right off idle when I just try to pull out lightly and also when Im just cruising barely on the gas. If I give it a little more gas its ok or if I punch it, it will get better. Also I noticed that if Im at wide open...
