Now for todays adventure.......... 1st I checked that brake fitting & it seems to be dry where I saw the leak, no more fluid on the rail & I drove it around quite a bit last night, maybe it was just the remaining fluid in between the line & the spring cover??? I hopin I'm done with that(Pedal is firm & doesn't give when I really lean on it.) would be  :cooldancing:

Then i played with the kickdown, had to take some adjustment out of the rod to have it all the way foward at idle, that in turn put pressure against the nut I was using to shorten the rod that goes to the carb, took out the nut & tension was released, so close (actually the far end of the rod) I can't use a fat nut, so I welded the rod & drilled out the hole & all seems good cept the tipping bar is NOT perfectly straight up at idle, slightly back, but I now have instant movement when you start to accellerate & I'm 99% sure it's full open when the throttle is the same.

Now I just need someone else there to check if I have full throttle when I mash the peddle!  :naughty:

Can't get her out till tonight they are paveing my street this week! :stomp: Rich.

OK common sense may kill what I thought was a common sense solution, k so I've been thinkin again :22yikes: so here's my thought.
In being so close to the end of that rod to the carb am I defeating it's purpose in that all these rods i've seen all have that long gap, so on release of the gas pedal the throttle will close but the rod will hang free, the way I ended up now the rod will be pulled back by the carb linkage, so whats that gonna do to the tranny downshift adjustment, if it has it's own pace for returning to the foward position  :dunno: Rich.

I'm sure Terry knows but my guess is that the slot is there for safety to allow the carb to close if the kickdown gets hung.....Seen plenty of problem solver bolts used that shortened the slot.
  The adjustment is the bolt in the slot on the kickdown rod .... re-read the instructions
 
  Linkage adjustment... With choke disconnected or held open have someone hold the kickdown lever on the tranny all the way forward (or make tool with spring to hold). Loosen kickdown lever adjustment bolt, holding the lever back, adjust the slotted bar forward till is in contact with the carb. stud.

Make sure you have the spring on the linkage like in the first pic  (dark one in line with the slot, not the red one)


I haven't seen it in the last few pics.

Just an FYI,the purpose of the slotted linkage is if the kick down linkage sticks,it will not hold the carb wide open.

Another thing also,if you see how level the linkage is in this pic, that is what you want (or close to it)

The lower front spring or the one that goes back towards the pivot assembly, that one broke on me I intend to get another.
OK, the problem seems to be the hi rise manifold, even with the throttle adaptor she's way short of getting anwhere near the back of that rod as per the instructions, I redid that yesterday before I welded across the rod, The nut on the  adjustment rod is about center, to get the tranny lever full foward, with that set the rod to the carb is fully extended, thats why I did what I did, so if this adjustment works then all I have to do is get a longer rod so I have that "safty buffer" so the throttle will close if the linkage hangs up?
there's  gotta be a bunch of you guys out there with non stock manifolds, how did you overcome this problem?  Sorry for being such a dummy, but there's gotta be a way around this, now going back again, when I got this car there was NO kickdown linkage, does that hint at something the prevoius owner might have done to screw me up!
No way will it ever be level with that manifold, if I raise the pivot bracket(mounted to manifold bolts) it's gonna play havoc with the lower rod I would think! Thanks,Rich.

On my car when I converted to an edelbrock performer rpm intake I converted to a cable kick down setup instead of the stock setup.
