Throttle Return Spring

So I have popped my throttle return spring.  I am not certain that I have had this thing attached in the right place on the carb.  It's on a Holley 750, single pumper dual inlet.

Anybody have a photo of the best place to secure the spring on the carb side?

Thanks

Thanks for the pics Just 6T9 CHGR, I really appreciate it.  It looks like your throttle return is hooked on to your throttle cable post.  Which is a great idea, except won't work for me.

Take a look at the pics, I have a GM *style* cable kickdown.  On the front of the bracket is a swiveling arm.  If I hook the spring to my throttle post like yours, the swiveling arm greatly interferes at half open to open throttle.  Getting that hung up could be a nightmare.

Now before, on my single spring, I am certain that it was actually hooked through the hole on the swivel arm.  Maybe that worked because it was a single spring.  With the dual spring I grabbed (don't want it breaking again!) the hooks fit through that little hole but the hook on the spring is at a very cockeyed (i.e. primed to break) angle.  It just doesn't seem right.  Hell, maybe I had it in the wrong place to begin with.

See the pics of what I am talking about, in the last pic I am holding the swivel piece that I am talking about...

So that grooved post sticking out of the end seems like a mighty fine place to hook the springs to.  As a matter of fact, that is what I have done.  While it has 2 grooves, that seems logical enough to me to be for 2 springs, the angle on the outer groove just doesn't work.  So I have them both on the inner groove.  Seems ok, but also seems a bit precarious.  I hope that it sticks on there.  What I'm left with now is wondering what the swivel bit is for if not for a throttle spring?  If the post in the swivel bit rotated, it would make sense, it could turn as the throttle increased and not bend the spring hook at an ill advised angle.  But it doesn't.

Where did you get your fuel lines for your dual inlet Holley?

It was a 750 vacuum secondary upgraded with a ProForm main body.   Its an auto car with a RMVB (no need for kick down linkage)
Took it to the track once with that set up.  Mild 440 with stock exhaust  Ran 13.55 @103

Looks like this now LOL ;)

That linkage stud is correct for an automatic car.  The extra notches are for the kick down return springs.

I have a RMVB but I now have the upper kick down linkage installed "for show"

Thank you!  So just so I am clear, the inner notch on the linkage stud is for the throttle return spring?

I am still at a loss for what that swivel piece is, I am starting to think it is for the cruise control (see the loose cruise control cable in the pics?).  But the fact that swivels as it does still doesn't make a lot of sense for that.  Seems a stationary post on the throttle arm would be easier and more effective.  Haven't really tried to get the cruise control going yet (or haven't returned to it rather) so I don't know.

Actually no.  In that pic I posted I did put back the Holley on after I couldnt get my $650 restored paper weight of a Carter to run right.  The stock iron manifold is on now.

Also, dare I say it, the Holley is off now in favor of a Thunder series 800 Edelbrock  :o

Throttle response is much better, better idle (not as dirty) and dare I say it again, gas mileage is better ;)

Have you run it with the 800 AVS/iron intake?

Chuck, I'd look into getting a dual spring for the 'carb-you never know when a spring can break.  I'm one to talk though, I haven't bought one myself...

familymopar

myk, that black spring you see in the pic is a dual spring.  I didn't really want it to happen again so that is what I got.  It is strange though.  It is not the smaller spring within a larger spring style.  It is 2 springs of equal size intertwined.  I may corder the other style as it seems safer to me to have one in the other, as opposed to intertwined identical springs.  It also seems a little flimsy, at least as flimsy as my old single spring, and it broke.  This was all they had at napa, and o'reilly's and autozone both told me a throttle return spring was a special order item, which kind of surprised me.  There are plenty on line and I will likely just order one.

After having my single spring snap I would highly suggest you invest the $6.00 or so on a dual spring!  Thank goodness that in my situation there was no harm done.

Oh I see.  Hey that's cool, too bad it didn't hold up. 

Love your new avatar pic, man!

Just in case anyone is looking at napa dual springs I wanted to be more clear, I think the way I wrote the last post was confusing.  The new dual spring has not broken, I was just saying that it does appear as flimsy as the old single spring and the old single spring broke.  The new spring, while it looks flimsy to me, is holding up just fine, after a week of use anyway.

Thanks about the avatar.  I see that the rear end got cut off so I am thinking about changing it again and doing the photobucket signature like you.  So I just signed up for photobucket and I am entirely confused.  We will see.
