Tim,
That springy bit under the throttle cable is part of the stock carb installation, so 
no surprise that it's missing from a DGV conversion.  Notice that there is a larger 
throttle return spring connected to the throttle wheel and to the engine bay valence?  
That's all you need for a return spring.  The original spring seems to cause some 
binding on the DGV throttle wheel, not allowing full throttle opening.

You will propbably need to bend the cable anchoring "plate" to get a better angle of 
attack for the throttle cable - I did.

I was able to find some small brass "barrel" pieces at a local NAPA store to use on my 
throttle cable.  They are threaded on each end and are drilled out through the middle 
for the throttle cable.  I had to drill out the hole for my throttle cable to pass 
through, as it was not large enough.  One screw "locks" the throttle cable into the 
brass barrel.  The other screw goes through the throttle plate from the carburetor 
side and then through a nut and then into the other end of the brass barrel.  The nut 
allows you to lock the screw to the throttle plate tightly, and then if you don't 
screw the brass barrel on too tightly, it will "rotate" with throttle travel, instead 
of making the throttle cable "bend".  If yo let the cable bend too many times, they 
simply break.   


Man - a lot of words to describe this!  I know my web site does not show good photos 
of this.  I'll have to go take some detailed pictures of this linkage. At least it 
works well now.  I don't break throttle cables and it allows wide open throttle.
