My Edlebrock works great, accept the throttle will not snap back to closed by itself every time. I get a slight hanging idle, which is very un-cool. I pulled everything apart today, and it seems the culprit is the slide return spring. Even without all the cables, it only snaps back all the way every time, if you let go of the linkage and let it 'snap'. If you let it down nicely, it does not return all the way; the last few milimeters are sloppy. It seems to me that if I removed the slide linkage and gave the return spring (rotary spring) another turn or two, this problem would go away. I am just reluctant to remove that circlip holding it on, as it is very small and very strong. (boing! wheredit go?). That, or add another external spring, which would be kind of cheezy... Suggestions?
