Throttle linkage?
Post by porkchop on Sept 21, 2006, 4:50pm

Ok now that the motor is in and running I need to figure out a way to hook up the throttle cable. Because of the way the carb has to sit on the intake with the primaries towards the outside. If the cable was about an 2 inches shorter I would have no problems. Is there a way to shorten it or does anyone know a cable that may be a little shorter? Any and all suggestions are welcome.

PC,

There are two things you can use, I have them set-up on mine, they are commonly available at autozone and other autoparts stores:

Bracket:

Throttle cable (cut to length):

Bling cable:

Lokar makes a nicer version of the cable too, better machining.

Another option if you have FSJ's handy in a yard, you can snag the pedal and cable assembly.

If you want, I can snag some pics of my setup...

Another thing I have been looking at is a little more stable bracket and here are a couple I've been considering:

This is what I think I will ultimately wind up with:

another thought... since that's a square-bore, can't you turn it 90* so the linkage is on the driver's side? Might make for easier geometry on the linkage/cable if it's possible...

Thanks for all the links. I will look into finding some of the cut to length cable. That may solve my problem. As for turning the carb, that is not possible since the primaries have to be on the outside for the performance factor. I was told this on www.stovebolt.com and www.inliners.org

Are you trying to get it to the FE in two weeks? If not, I have a cable out of a '78 C10 that is probably just enough shorter for your needs I can bring with me. Matter of fact, if I can find it, I will bring it no matter what.

There is no way I will make it to the FE. I still need to get the jackshaft figured out. I need to get it ready for the Marine Corps Ball in November and the Toys for Tots drive. So please bring it with you I am sure I can use it.

Does anybody have a picture of the stock Gas Peddle linkages? I took mine apart a few years ago and had to weld up some stuff to get it to work and it doesn't work too well. It binds and has other issues. For the throttle cable mount on the engine I got my buddy to make me something up at work where he can punch out 1/2 inch squares and other cool things. That end of the cable works great just trying to get my skinny peddle to work better.

hey Porky, I was going to suggest putting a loop in the cable..... You may need to get a slightly LONGER cable to do so. Chevy did that to get around the cruise diaphragm on this big block.

or use the bracket. *shrug*

If I'm understanding you correctly, you have the carb mounted 90 degrees off from what a v-8 would be with the throttle lever closest to the firewall meaning the cable has to fit between the carb and the head? And this is for better performance out of the inline six due to having the primaries an equal distance between all the cylinders? IF that is the case, it seems the same theory would work with the carb mounted 180 degrees from where it currently is and the longer cable could simply be between the carb and the fenderwell. Just a random thought and maybe way off base... Bill

Looking at the pics now, that might mean you'd need an even longer cable so really either way, you're not gonna get it with what you have I guess.

The reason they say you can't put the secodaries outboard is because when they open they will not give equal amounts of fuel to cylinders 3-4. I am getting all this from the guys over at inliners.org. But there is still some conflicting post that I am trying to get worked out. Some on there are even saying the carb can be mounted the same as on a V8 with no ill effects. But it doesn't seem like it would distribute the fuel equally that way to me. More to follow.

After much debate, I am going to mount it with the primaries toward the engine. So it will be 180 out from the pictures above. The existing cable will then work, still maybe a 1/2 inch short, but i can get it to work. Thanks for all the suggestions. I will keep them in mind in case I can't get the performance out of the engine I want. But according to the guys on inliners.org there should be no ill effects.
