throttle linkage question/HELP
Ok. Here is the story. 79 f150 originally had a 300 six in it, previous owner installed a 360.
The linkage on the firewall to the rod the connects to the carb has a small metal clip that slides over the rod with the hole in it where it joins the 2. It popped off in the middle of a truck pull and didn't work out so well. I'm wondering is there any tricks to keep that from happening? When i putit together should I squeeze it tight with a pair of pliers? I don't know how to explain the linkage all that well i'm just hoping you know what i'm talking about. Its not the ball connection on the throttle shaft its the rod that connects to the throttle shaft where it connects to the linkage on the firewall.
Thanks
andy

Like these?
Ford Mercury Lincoln carburetor linkage clips: eBay Motors (item 370395798927 end time Jul-12-10 17:22:18 PDT)
Make sure the linkage is straight, not at an angle that will pop the clip off the rod. How much does the engine torque over? That could be an issue.
Consider a cable set up?

Yup it has those. I'll check to see if it is straight, and i'll see if i can squeeze it tighter with a pair of pliers. A cable setup would be nice, any thoughts on how to go about that?
It is for a sled pull truck. IT has only happened one time in the last few months of driving/ pulling off and on so it might just need to be realigned.
And i never thought about the engine TQ problem.
Thanks

There are a couple of ways to do the cable. As stock, our '66 wagon had the throttle pulling directly on the cable and it ran the whole distance to the carb.
You could terminate the mechanical linkage on the firewall and hook it to a cable, then to the carb. With a bit of a loop in the cable, engine torque etc doesn't effect the pull on the cable.
The trick is to keep the mechanical linkage off the engine, and connect through the flexible cable.

My cure for this stuff was to replace all the linkage with a later style cable system, including the cable, the foot pedal and the carb mount. I would just troll the junkyard looking under Ford hoods. Sense I measured to see how long a cable I needed before I went. Usually the big Fords, Mercs, Lincolns, big SUVs and trucks were golden for this.

Keep in mind the cable we are talking about is like motorcycle cables--a shielded cable where the shield is fixed near the end. The suggestion Bear 45/70 made is probably the best fix--adapt an oem set up.
