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?
