Throttle cable conversion

Sorry to hear about Rocky Racoon's visit and his appetite for upholstery. I hope securing a new seat isn't too much hassle or money. The poop you'll forget about.

happy new year, Mark

Farmer: thats a used cable I salvaged from the aircraft junk pile at work.

Even though it is 12 feet long it still returns to idle with just the factory spring on the throtle body. Its inportant to use a good quality cable that most smooth with low resistance.

You have to be carfull about what you build. The cable should be a puller and have the return spring at the throtle so the engine will go to idle if the cable breaks.
Some hot rodders build up a throtle linkage system so tough to use that it has to have a bledy door spring to return it. You want to avoid building such a mess because the spring will not only ware out the throtle shaft on the carboretor real fast but holding the gas pedal down will give you back pain on long drives and driving away from the curd slowley will be imposible.

Air craft can take off from a 120* runway is the desert summer and clinb up to 15,000 feet altitude where at 150mph the temp of the cable goes to about -20* below zero. The cable has to stay free moving. Thats why aircraft control cables cost money. They are made to much higher standards then any other type of cable. If you look in the "Air Craft spruce and specialty cataloge" which suplys cables for home built aircraft you can get reasonably priced high quality engine control cables. like $50
you can also get thread on extensions and clevis or ball joint ends like you see on mine.

Just Converted my throttle linkage to a push/pull cable! It only took a few hours and man, what a difference! Thanks to everyone on this thread that inspired me.
I can take pictures too, if it'll help anyone else.

The more pictures the better...I might as well as get mine on here too.

Hey Hotrod, throw some pics up here...love to see what you did. My linkage is pretty messed up, there's actually a bungee cord being used as a return spring...yea, afu'd. Next project on my list.

I promise, I will, but the temp here is -12. It works so nice!

Going to revive this thread, great info.... Anyone have a part list to do this cable conversion? I have a rigged setup on my 69 v8 someone did that works very poorly. The aircraft cable seems like the best safest way?

Jeremy,  Here's the list of parts that I used on my '65, all from Jeg's.

1. one five foot throttle cable, 3" stroke. Part # 555-15705
2. two each quick release carb link swivels, 1/4"-28 male x 10-32 female.  Part #555-15734
3. one steel carb link bushing. 1/4" non-threaded. Part #555-15220
4. two each clamp and shim. Part #555-15736

I used a length of rigid copper wire, bent to the desired position, to determine the length of the cable. Mine was on a first gen so your's could be a little different on the '67.
