Throttle Cable Bracket for Demon?
I got the Demon back from "The Carb Shop". They say the malfunction was a bad needle. We shall see.
The throttle cable bracket spins on it's bolt. I have a Holly bracket and return springs. The return springs pull the bracket so it spins around
90* and looses its spring tension.
What can I do to tighten the bracket to the carbs base? I'm thinking about cutting and beating on the bracket flanges to tighten it to the carb base. Does any of this make sense? I want to do this right and I don't want to pay for fabrication that I can do myself. Any help out there? TIA

I think your talking about the original quad throttle cable bracket not having anyplace to stop from pivoting on the Holley setup? If thats right , Then you need to do a Little Fabrication on the holley to make it have a tab on the base so the 90* bend on the Original bracket will stop it from rotating. Or upgrade the entire cable to the Lokar type. Many c3's have upgraded throttle cable assy's.

I have the better cable. You are right about the Holly bracket. I've done enough fabricating to avoid if possible. Looks like nothing aftermarket is ready made? I have a hacksaw and small vice, I hate to get started and not be able to finish. Thanks for the help.

Nice Job!
Binnie: I don't have the 2nd brace like you do. I'm going to try to cut the boxed section and tighten it up around the carb base.
My vice hasen't been beat on much, time to try.
I'll keep the forum posted.

I use a Lokar throttle cable and bracket for my Demon. The bracket has a small stop to keep the bracket from turning.

I have a 750 Speed Demon on a ZZ454 in a 71 vette (originally 350). I took this 1st picture from another thread. Will the below bracket work on my car? The OP mentioned his being a 75, but not sure if this same bracket would work on my 71? CSR's website says it fits "GM snap-in cable" on 4150s. I circled my throttle cable in the 2nd picture...it looks slightly different than the 1st picture (i.e. his cable has a square portion that is connected at the back of the bracket (closest to firewall).
Where does the return spring attach to in the 1st picture? Maybe a point on that red bracket underneath?
How do I attach the throttle cable end to the bracket on the carb? I'm not really sure what kind of attachment hardware would connect the two (red circle on the 1st picture). Thanks a ton for the help guys!

to attach the cable to the carb linkage you can buy the edelbrock fitting that goes into the hole and has a nut on the back of it and your linkage slips over it and it has a securing pin that keeps the accelerator cable from slipping off.......in the picture below i am using the stock qjet style one...
you can always attach the spring forward to the front of the engine

I won't be going to a 700R. Thanks for the tip on the fitting. I looked up the original part number for the fitting in the AIM (no, I don't know why I didn't think of that earlier) and came up with this:
. As far as I can tell the stud just pops into the throttle cable. I don't see where there would be a provision for a retaining clip. Does anyone know if on 71's the ball stud is just held in place on the throttle cable by "force" (i.e it pops in there and is secure)?

ok i see it in my mind now......the clip has the slot only wide enough for the smaller diameter and then has a C shaped clip that clips over the rod to lock it in place....these are standard clips and are not fancy in any way.
looks something like this

Thanks Bob! I do have that c-clip type thing, I just didn't know that's how it worked. Now the next question is the bracket on the carb has 4 different sizes of holes (see the 2nd picture of my previous post). What size of thread on the stud do I need? Seems like I could buy one, but then it'll only fit one hole (as it would be too big for the other holes). Any idea which is best for the speed demon?
Also, does anyone know if my throttle cable will work with the CSR630 above? I don't have that square part on my throttle cable, so not sure if it'll stay in the CSR bracket?
And one more...recommendations on which return spring to use? Thanks a ton for the help!

Found the holley studs on Jegs, thanks! One lingering question is the throttle cable working with the bracket.
I circled in green the square part that the 75+ cables have, but mine does not.
I'm looking at using this: Jegs Throttle Bracket because it also has the return springs. However, will my cable stay put in the part that has the green arrow below?
In the above picture, it appears the cable has the square piece that all the 75+ cables have. I'm confused if this will work.

your type with the "tube on the end" has to use a bracket that clamps it in place like the cables on a lawn motor......it will not work with the square type bracketry. I have to imagine LOKAR has bracketry that will work.....look at a street rod magazine in the drug store for other sources.

Do you have a picture of that type of bracket? I looked on Lokar and Jegs and haven't found it (or at least I don't know what I'm looking for). On the flip side, is it much of a pain to just get a new throttle cable from Lokar and install that?
