Cable Conversion

So I kind of rushed through this mod
So not a lot of in progress pics

I cannot state how necessary this mod is for tripple carbs
I'd imagine it is worthwhile for the OG SUs
I retained the original linkage to be more period correct
I did not want to alter the character of the car
For some reason I got a bug up my ass and got parts to convert to a throttle cable

There's not a lot of documentation out there on how to do this
I was left to my own
My main inspiration was brake cable setup on my BMX bike
After studying how it works for an hour I started the project.

Step 1: Parts

The above product bolts on to the weber linkage arm
the end of the brake cable wire inserts into the tip
the tip moves freely in the direction of the pulling force

In the series of pictures below, you can see how it works.
Gravity, in this case, is the pulling force.

First step is to remove the gas pedal
Wish I took more pictures of this...
I drilled out the ball on the stock pedal arm
I fabbed a new lever end to accept the brake cable end

Crappy picture, but here is what it looks like

Once that is done you can come up with a fire wall mount for the cable sleeve end
I removed the grommet for the original linkage
Utilized the cable adjuster nut purchased from Pierce
Put a big ass washer with rtv on the engine bay side of the firewall to clean it up

Now you need to make a cable mount for the other side of the brake cable
Make sure its thick gauge steel
My first bracket was too thin and bent
I mounted my bracket using the bottom two velocity stack mounting studs
It is under the carb so as not to be too visible
This is the best pic I have at the moment

 You want to maintain as linear of a path with the Lokar part
So as not to cause the wire to rub and prematurely wear

Here you can see how I mounted the linkage arm

 I also added a return spring to help the carbs return to ZERO

All done and hardly noticable
Driving is much improved and I'd say more enjoyable

Not my best write-up due to my hastiness
If you need specific pics or information feel free to comment & I will follow up

  2. I need specific pics or information. :)
    I'll hit you up when I get to this point.

    I can feel the difference just looking at it.
