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)

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)

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.
