Throttle cable for carbs, How do you run it Options

[VaccaRabite]

So, I need to order a new throttle cable, which will be run for a carbed motor.

How do I run the cable to the carb link bar? Is there a pulley or channel or something to make the bends easier? What do I need to do to get the leverage to actuate the linkage? Do I need to order a special throttle cable (longer or somehting?)

I'm dumb, pics are helpful. (IMG:style_emoticons/default/huh.gif)

I've been wondering the same thing as I'm almost done with my 2056...

Is that a stock -4 throttle cable? Thanks for the the pics!

The stock cable works fine the carb kit should come with a bracket to hold the cable. I have put three or four dual weber setup's on 914 and never had any problems.

I'm not at home, but I'm almost 100% certain that my CB Performance kit did *not* come with a bracket to hold the cable. What kit are you using?

Thanks.

All my stuff is second hand. If I need to order stuff, what should I order?

Wait a second... That looks like a frightfully easy bracket to fabricate from steel I happen to have sitting in the garage. I just need to change how my linkage bar is set up.

Aaron,

Yes, stock length cable--but I think it's a "terry cable" or something I got from Performance Products long, long ago . . . .

The Dell's came with a cast bracket, but I could never get it to work the way I wanted, so about a buck's worth of angle brackets later I was in business. Been like this for over 20 years with no problem . . . .

I love the DIY aspect of it...

Vacca Rabite,

I'm totally with you on the second hand stuff... I even have (very minimally) used Pagid Orange pads on the car!

My cable comes out of the fire wall and straight up between the tin and rubber gasket in front of the fan, it has a tight bend by the fire wall and I am always afraid it will bind or break.

[anderssj]

If I get a chance I'll take a look at my cable routing--IIRC, it comes out of the tube in the firewall, up through a grommet in the cooling tin, then held in place by the two nuts at the top of the bracket.

It may be a couple of days though--gotta do a brake job on son's volvo this PM (meuller knows what I'm talking about)

[911quest]

If you get the hex bar kit for a type 4 it comes with the braket that mounts to the top of the case,

This is the nicest home made throttle stop bracket I've seen. The cable runs at a more relaxed route avioding binds.

Man, that is really nice. I may try and replicate that...

I just looked on CB's site and this is pretty much what my kit looks like:

...no bracket.

OK, a couple more pictures courtesy of CB Performance (these came with the Dell kit all those years ago). One shows all of the pieces, the other is the assembly guide with my notes . . . .

There are a number of ways to put the linkage together--I wasn't too inventive back then so I tried to make mine match the picture. Knowing a little more about linkage geometry now, I could probably improve things but it seems to work well enough with no drag or binding, so it's kind of low on the list right now (IMG:style_emoticons/default/dry.gif)

I am looking at the first pic, and I guess I am missing something. Do the Dell'ortos open when you pull UP on the linkage? My Webers open when you push down on the linkage. So these pics with the cable in the front of the motor and the arm pulling up on the carb linkage confuse me a bit. Please clarify.

Joe,

It depends on where you put the lever on the cross bar.

Under the cross bar it rotates one direction
If ya put it on top of the cross bar. It rotates the opposite direction. just depends on how you set up your carb linkage and which way your carbs are put on. (outside VS inside linkage)

Does anybody know who made that nice bracket above? I'd love to get the dimensions off of it...

True, given the pull direction on the crossbar lever is the same.

The direction of hex bar rotation needed to open the throttle doesn't change
by moving the cross bar lever.

So what's a person to do if you want/need to actually change the rotation
direction of the crossbar? because say you want to keep the lever down low yet
you need to pull forward or backwards and that rotation direction doesn't open
the throttle?

You can change the direction of rotation needed on the crossbar
depending on what you do with the arm/lever on the Carb shafts. The kit
from CB comes with new arms/levers for the shafts.
(you can see them in the middle of the CB kit from the link mentioned earlier)

Depending on how you mount the carb shaft arm either pointing to the center
of the car or twards the outside of the car it will change whether you push down
or pull up on the rod to operate the shaft.
It does not change the direction the shaft rotates but it does change the
direction the crossbar needs to rotate.
I took a few quick photos to show this:



The top photo mounts the arm point towards the center of the engine and
will need the rod to push down on it to open the throttle.
The 2nd photo mounts the arm on the outside and will need the rod to pull up
to open the throttle.

Some folks also mount the cross bar towards the rear of car instead of towards
the front. That also flips the direction of pull on the crossbar lever but does
not change the needed direction of rotation on the crossbar.

There are enough combinations to allow you to pull up/down/forward/backward
on the crossbar lever depending on where/how you mount your carbs and
attach your carb shaft levers.

On the actual throttle cable bracket, it amazes me that very few of the
kits include one. Most of the crossbar linkages leave it up to your imagination
on how to do this. This is true of the CB kit.
Triad's linkage kit includes a very nice cable bracket and they will sell it
to you separately if you just want the bracket.

I have collected many pictures of different folks solutions.
A few have already been shown.
Here are a couple more photos of the many I have including a new one I just
saw which is on page 31 of the latest AA catalog.
Perhaps George would sell this separately from his FI kit.
Here is Georges pulley bracket:

Anybody know who makes this one?

Another rear pull setup.
