OK, it's become a disease. The first rebuild came out SO good (with your help) that I just grabbed up another fifteen dollar wonder. This time a Ford Holley off of an '85 Mustang 5.0.
Got a question regarding the linkage that is sort of strange.
There seem to be three "arms" on the throttle plate linkage. The inner and outer are connected and move together in tandem. The middle arm is free moving, but has a small screw in it that hits the inner most arm causing the middle arm to move with the other three when the screw head comes in contact during the throw.
HOWEVER, this small screw also prevents wide open throttle from occurring, almost like it's some sort of governor.
I was also wondering if this middle arm might be connected to the transmission rod as a kick-down actuator.
The carb that I grabbed up looks a great deal like this one:

The arm in question is shown here as the shiny silver arm just inboard of the gold outer most arm.
I SERIOUSLY need some help with this and I promise to stay away from two barrel Holleys in the future if you'll just help me with this carb !
Thanks ! ! !

Yes, it's a kickdown for a pre-AOD transmission.
Thanks ! My engine and trans came out of an '84 Mustang automatic,
Can I alter it in some way to work with the metal rod on the AOD trans? I know about the trans cable and how to attach that to the throttle linkage, really don't know anything about connecting/adjusting the long metal rod coming up from the trans.
There were fittings and such on the CFI, but not on the carb.
Any help?
HUGE ! ! !
Thnaks,

The trick is that, if I'm getting my transmissions straight, the AOD does not use a kickdown linkage like the older units did.
Older units = the lever only was there for kickdown. It didn't move until 3/4 throttle or so. You could do without it and be just fine aside from having to downshift manually.
AOD = the cable adjusts line pressure. It needs to be set correctly and over the full sweep of the throttle motion, not just at the very end. Without it, your transmission will eat itself very rapidly.
Solution IMO is manual valvebody and eliminate the bugger. But that's always my solution.
I always thought that the kick down trans rod was discontinued early on as well, but the '84 Mustangs with the CFI had both. The rod AND the TV cable.
Been really trying to figure all of this out, but no info out there. Of course, the big problem is in the AOD trans and how prone t is to destroying itself if everything isn't set up totally correctly.
I'm cautious of everything with this swap, seems like little mines set everywhere I step.
Any other additional info would be TERRIFIC ! ! !

Whew ! !
Just got this thing totally figured out !
My engine (5.0 from an '85 Mustang) has a TV rod rather than a TV cable. The rod acts as both the TV rod and the kick down rod. The TV cable was introduced the following year. What I thought was a TV cable, is the cruise control cable.
Yes, I AM an idiot ! ! !
Checking the linkage on the CFI, the rod engages around mid throw and the two barrel that I'm using has a kick down linkage that I can fit a spring loaded bolt to that will act in the same was as the linkage on the CFI, just gotta be REAL precise in setting it all up.
A word of caution to anyone running a Holley two barrel on any car, you gotta remove the little screw on the kick don arm of it definitely will bottom out before the rest of the linkage and only allow for 3/4 throttle. Check it out, you may still have the screw in place robbing you of WOT.
Thanks for the help ! ! !
