GMR Just called Edelbrock - they chastised me for removing the shafts and blades and said the only way to get another spring is off an old carb.

GMR I don't detect any binding. If I operate the primaries alone they seem ok to me in snapping back. When I operate primary and secondary to wot, it seems the primary is trying to help push the secondary closed when I let go. If I don't attempt to wind the secondary spring at all, it is loose, has no tension at all and both shafts hang open in my example above. If I operate the secondary alone it just hangs open when I let go. I tried to wind it once, and that helped, but not enough.

Should I have to wind the spring in the first place or should it automatically have the proper tension when I just slip it on?

The bottom spring (secondary throttle) is what I am working on now. When you work the throttle shafts to WOT the 2 shafts and their plates do not snap back like they should. I know the orientation of the spring but not how to get the correct tension. I've tried to wind it by pulling on the hooked part that goes arount the linkage arm but I think I'm going to ruin the spring that way.
Have you loosened the throttle blades to center them in the bores? It can take several attempts to get them centered w/o friction.

If the spring's correct, it won't look bunched up; it'll be nice and even, like the photo shows. If you wind in more tension, the coil starts to distort.

If the secondary blade alignment is a problem, if you loosen the blades a touch, and if the spring's on right and the tension's right, it should snap back correctly. Unless the spring's sprung.

Does the primary side snap back right? What happens if you disconnect the primaries from the secondaries?

Edelbrock secondary throttle spring install

Have totally rebuilt a pair of 1404 carbs including removing/cleaning throttle shafts and replacing throttle plate screws (with help from this forum). Had some difficulty with the primary shaft linkage spring install but eventually got it.

The secondary shaft spring is another story. Anyone have a method of getting it on and wound tight enough correctly. I checked the wiki but didn't find any help there.
