Well I thought I asked this before but I can't find my original posting on it, so I'll ask again (and if I did ask, I'm sorry if I sound like a broken record)....
1969 Charger 383 4-bbl (stock 1969 cast iron intake squarebore manifold) - the throttle sticks at above idle until I blip the gas pedal to get the throttle to snap shut. It won't close completely down onto the idle stop screw unless I push it down. And it only does this when the engine is running- if I shut down the engine and move the throttle open and closed there is no sticking and the throttle will close all the way down. During this, I can feel no binding- it's only if the engine is running.
This is on a Edelbrock 1405 carb by the way. THe only thing I can think of is to go to a stronger spring or shorten the one I have, but before I do that is there anything else I could/should check?
Thanks!

One question I did mean to ask- on the idea of relocating the spring on the spring bracket - I'd rather not drill another hole in the one I have. However I'm not 100% sure that the one I'm using is correct for this setup (when I got the car the engine was in pieces courtesy of the previous owner, so I had to put the engine back together) - so does anyone know what is the correct height of the spring bracket for a 1969 BB Charger? It might be that I'm simply using the wrong bracket (or wrong spring- this one I got from Year One years ago). Also, it's a 4-speed so I don't have any extra linkage for a auto trans.

I fought this once before. Posted on Moparts, recorded on youtube, Holley tech line, asked 100 other gearheads.
Until one day I decide to throw a new throttle cable at the problem.

Ok- anyone know where I can find a throttle cable (new, preferably) for a 1969 BB Charger? Other than Megaparts and Year One (one is out of stock and the other is out of this world)....

try removeing it and use some 3 in 1 oil down each end to lube it. work it by hand and see if it has any fray to the cable inside. I lubed up a bunch that were dry and they worked well after that. on my 68 Dart,the cable had a square end for the firewall. I used one off a 84 /6 truck for a longer cable and 4-v carb swap. might check to see if you could use another cable off another model.. say charger and the price goes up.  only down side to a heavy throttle spring would be the wear on the throttle shaft and carb body resulting in a vac leak.IMO I have had a few Q-jets bushed to fix the shaft vac leak.

Well I went ahead and disconnected the carb end of the throttle cable and checked it to see if could feel a 'catch' - didn't really feel anything that would indicate a frayed/broken cable. It actually had a pretty smooth movement to it  I was actually dissapointed in a way... but at least it looks like it's good and I won't have to hunt down a replacment (and apparently nonexistant) throttle cable... But I reconnected the cable to the carb and adjusted it per the FSM. I've got my distributor apart and the parts won't get in until next week- when I get it back together I'll check again and see if the stickiness is still there. I'm wondering if I had the cable adjustment correct- when I last installed it, I may have not given it the 1/4" slack that the FSM recommends. But it's got it now so we'll see if that helps. If not, I'll be back...

Any suggestions?
Hello David. (#2) replace the cable
Hi Robert!
Yea I'm beginning to think that myself. I'm fairly sure that I'm running the correct spring, and while it's possible that it might be fatigued from age, the fatigue shouldn't be so bad to account for a problem with overcoming any cable friction. I might have to just bite the bullet on this one and get a new cable.
EDIT: For grins I looked up the red spring and I was wrong on the application- apparently it's also used in '69 BB applications. Does anyone know what the differences are between the green and the red springs?

I think my cable is original.... at least I don't ever remember replacing it. It certainly wouldn't hurt after all of this....
