Per the throttle not returning, there are only about 5 things to look at, I give the most likely first: Please note there is no need for extra throttle springs; the one at the firewall bracket is sufficient. I regularly remove extra springs from customers's cars after putting the linkage to standard condition.

Has the bracket at the firewall, driver's side, collapsed so that the vertical portion is touching the firewall? This alters the geometry and the spring will not be effective. Shove a piece of rubber behind it for a temporary fix. Mine has had a shock bushing shoved in it for about 15 years.

Has the connecting link from the back of the engine been adjusted too short or bent?

Has the L-shaped link that adjusts the fast idle speed been bent too long?

Did you have the throttle plates off of the shaft and perhaps they are not centered up in their bores?

Is the external link that works the metering rods installed right side up? It is possible to put it on the other way, but then it binds.iirc.
