throttle cable by lokar
i just cant get it right. no matter what i do i cant get my lokar throttle cable adjusted properly.
i have tried to install it with the pedal all the way up and the carb at idle and i have tried to install it with the pedal all the way down and the carb at WOT.
every time i end up with either not enough travel on the carb or not enough travel on the pedal.
i have looked at a couple of install instructions around here but i must be an idiot because everyone just says its easy.
i am gauging all the way down on the pedal by the th400 kickdown clicking when it gets hit.

i guess the pedal arm may be bent. it goes all the way to the floor and clicks the transmission solenoid when the cable is unhooked from the carb but when i hook it up to the carb the throttle blades go to WOT before the pedal gets all the way down. i even read where you can put a piece of hose on the arm for the kickdown switch to make it engage but that shouldnt be necessary right?

i have tried a few of them.

Ultimately, if your car idles fine and reaches WOT, the only other thing it needs to do is hit the switch. Doesn't much matter if the travel is different.

Once you get idle to WOT with the pedal travel the switch will set itself if you do the following.
First make sure you get idle to WOT with the pedal travel. Adjust throttle cable and/or bend the pedal rod a bit. Make sure you don't have too much stuff under the pedal like heat insulation, carpet jute, carpet, floor mat, etc.
Push the switch lever all the way forward until you hear it click. The next time you go to WOT the switch will set itself.
I struggled with the same issue and I finally had to remove the pedal rod and bend it a bit to get fmore travel and take the slack out of the cable AT THE PEDAL ROD connection.

Throttle Cable
Baxsom, don't mean to Hi-jack your thread but I have the same question. I pulled the cable tight and connected to the front-most hole on the carb pivot. The pedal is nice and tight but at WOT, the secondary opens just a fraction. If I do it by hand, I can get another 1" or so to full open on the secondary. Bent floor pedal rod?

i tried the adjusting the switch. i cant get it to move forward towards the seats.
it will only go down towards the engine. it goes to the halfway point up and then stops. i dont want to force it.
i was able to bend the rod a little forward and i think i got it.
it clicks now when it goes down and looks like it goes to WOT on the blades.
now i just need to wait for all the fuel the pumps sprayed into the carb to evap so i can try to crank it.

Next time put a rag in the carb to absorb the fuel as you pump but PLEASE don't forget to take it out before you start the engine.
To be clear, I was talking about bending the rod rearward near my red circle to take out the slack. That gave me more travel and some more adjustment at the carb end of the cable. THEN, I reset the switch arm.

Throttle cable
Thank you all for the great information. I removed the pedal assembly and bent the rod a bit as suggested. The pedal is much higher but still good and the new Quadra-jet opens all the way.
Thanks again to all.

Good to hear you now have WOT. Now just be sure that there is still a little movement left at the carb so the cable has no strain at WOT. You probably now have some room for adjustment at the carb linkage.
