Throttle linkage

[Guest dylans1952]

The previous owner of my truck decided to redesign all of the carb linkage. the Throttle return is a spring stretched from the carb's throttle valve over the manifold and hooked onto the heat riser. I can't figure out how it was originaly. so if anyone has any good pictures the throttle linkage they would be very helpful.

Not sure about the 50's cars but there were some that had a brace to the air filter it had a hook on it that accepted one end of the spring. the other end went to a notch in the bell crank where the rod from the firewall attaches. The flat piece is attached to the head where the spark plug wire loom attaches.

In the pic, I replaced the air filter brace with a piece of flat stock with a notch in it. This replaces the hook on the air filter brace. I have also seen a fitting screwed into one of the headbolts that has the treaded head, that the spring attaches to. If you have one of those head bolts you can make a facsimile, by welding a washer to a bolt or piece ot threaded rod to accept the fron end of the spring.

The 39-47 trucks the spring goes to the firewall to the head of a cotter pin.
