396 Turbo Jet accelerator linkage - The 1947 - Present Chevrolet & GMC Truck Message Board Network

burb71 · 08-07-2010, 01:04 PM

Can someone please tell me what is missing from my 396 accelerator linkage?
To the right of the linkage is the kickdown swicth.
What is the swith to the left of the linkage ?
Also what is missing to hold the rod in place?
it has a little cotter pin but there has to be something more

If anyone has the parts to sell please let me know.

There is supposed to be a little metal piece, that attaches to the throttle linkage arm of the carb. It kinda looks like a flat piece of metal that was bent into a 90 degree angle. It pushes against the kickdown plunger. The other thing is your idle solenoid. When you turn on the A/C, the plunger pushes on your throttle arm to increase the idle speed, due to the extra load from the compressor.

If you search "kickdown" in parts board you will see pics of the piece you are missing posted by LIVRAT and CPNE. Sharpie

Heres a pic. The linkage looks somewhat different. Possible carb change in the past?

Thanks for your pic john, that little paddle on the linkage is one part that I need, its in reproduction so I'll get one.
But the rod on mine is not the same as yours.
The carb is a rebuild unit, my accelerator rod is the same as the one that board member too much stuff has on his 1969, 396.
Mine is a 1968, what year is yours?

Guys, I'm gonna move this to the '67-72 message board - that's a better place for it.

I'd check to see that it's the right carb for your truck. I swapped in a new carb on the weekend and even though it was the exact same model number, it had a different throttle arm so I had to rig up something for it to work with my throttle linkage.

Over the years, people have changed manifolds and carbs. Mine should have had a 292 inline six with a two barrell carb. It had a '67 283 V8 in it with a quadrajet 4MV when I got it. That engine should have had a Rochester 2G but someone changed the intake manifold so it could have a 4BBL.

I put another rebuilt quadrajet in but it was probably from a car instead of a truck so the linkage had to be modified.

Good luck.
