So we're having throttle issues (acts like it's bonding up somewhere) and I didn't take any good pics. I just found one mistake but I am hoping someone can take pictures of all their throttle pieces on the car. 1970 4.2, 2 carb set up.

 

The most common area for binding is where the throttle linkage rotates past the frame member(between the two carbs). If your rubber engine mounts have broken down, they will allow the engine to settle a few millimeters... just enough to cause interference at the frame. Check there first, if it is binding, a quick fix is to carefully jack up the engine to allow sliding a couple large washers as shims under the engine mount on the carb side. Grind an opening slot in the washer so it can slip in under the mount. Of course replacing with new upgraded mounts is the permanent fix.
Other linkage issues may be more challenging.

We got brand new engine mounts. We played with that area after I got your reply. Nothing really changed. Thinking it's somewhere else and we put something together wrong.

 

My engine bay should be similar to yours so what pics, & from what angles are you needing?

Willow, Its GTJOEY, there IS A CENTER LINKAGE WHICH DROPS DOWN BETWEEN THE TWO STROMBERGS,
Make sure the clips are locked onto the rods and completely locked in.
You said its binding. Make sure the butterfly linkage is free and not rubbing inot the heater hoses or anything else.
You changed the engine mounts, did you adjust the rear stabilizer mount?
The series two set up is very cumbersome, check where the shaft from the fire wall to the carbs is locked in correctly.
You did put back the return springs right?
Ahhhhhh triple su's.

Hey joey. Yeah the center arm between the 2 carbs I found wrong, it was backwards and up against the intake.
i think the springs are on right, need a picture to confirm.
We put a new restabilizer in as well.
i didn't see it hitting anything else, like Hester hoses

 

Hey Alfred,
pictures of the linkage around the carbs, and on the firewall would help.

 

Good job! still binding?
If so check the shaft connections.

Yeah still doesn't seem right

 

here are some pics

 

Awesome thanks Alfred. Can you take pics of under the carbs? Like the Springs and stuff?
So far everything looks right

 

more pics, as you can tell I have done the "Strangleburg fix".

 

What's the strangleburg fox about?

 

Peter Crespin detailed how to modify/disconnect the secondary throttle link at the Carb. search Crespin mod, or 5 minute strangleberg fix.

Ok I will google it, the link in your link takes me to some jazz site lol

 

Still having issues with the throttle

 

Found why it wasn't idling, so now it idles fine
