This is a safety item...

Prior to re-installing the accelerator linkage, I casually checked it's swivel ability. YIKES!!!

What swivel ability? It was frozen solid.

Which brought me to imagine how many old cars out there have a gradually freezing-up accelerator linkage. The problem was in the center tube which transits the transmission tunnel above the gas pedal.

It took a few minutes to get it apart without damage and then a few more minutes using the emery cloth and white lithium grease to get everything ship-shape and free-wheeling.

How's the one on your car? Will it always allow the throttle to return to idle? No spring in the world would have returned mine.

Good catch. Thanks for the post.

Another good idea is a double spring - in case one breaks. Mine is actually tripled. The front 2 are SS concentrics used on SBs everywhere. The rear spring balances the pull that the front 2 exert on the throttle shaft - in order to minimize wear on the throttle body. The fronts attach above the pivot point, and the rear attaches below it. That allows me to rest my size 13 boot on the pedal while driving all day.

Good catch.I just checked mine and its fine.I have often commented on How many UNSAFE collectable cars are on the road these days.they have perfect interiours,perfect paint and chrome,But the mecanicals are untouched except for a good running motor.

I am just back from a vacation and was visiting a Collector car shop and was appalled at the condition of the cars for sale.The best way to describe them were old ladys in new dress's, pull off the new dress and they are still old ladies

I am just about ready to pull my 67 deville out of hibernation this sunday and the first place it will go is up on the lift for a mecanical inspection before I start driving it again

Saftey should always go before cosmetics.But its not always the case

I have the same problem.

Well it's sticking
But with a BB, this little problem could be a BIG problem. My question is: How do you dismantal it?

Since mine was a body-off project, it was easy to remove the assembly as a unit without an engine/transmission in the way. If yours is still in the car, remove the bolt/nut and upper linkage (shown in the photo) on the transmission side and then the two small bolts holding the lower linkage to the transmission tunnel (also on the transmission side).

Once you have it out of the car, soak the center section in WD40 for a day or two and then clamp it in a vice and gradually work it loose. Once you can get it completely apart you will want to clean and lubricate the center section.

Thanks for the info. Yes I have the engine in the car, and it's a BB.

So the 3 bolts I need to remove, are on the Transmission side. Chevy makes thing so easy

Hi all
Another good tip there 67
It's always good to check that kinda thing, As with any maintence proceedure
the carb is usually on the top of my list, I use gumout and wd-40 and a close eye, Thank god It's never stuck , I've found the butterfly stuck in place before
and the cleaning made it start and run a lot's better
Thanks Again for the reminder
