I replaced that pesky accelerator pump and now I have what appears to be a tight spot or bind in the linkage....I took it apart and put it right back together.

You should be able to move the linkage at the carb. If it's that tight, something's wrong! That's why I kept the quadrajet!

Looking at Barry's response makes me think you don't have the q jet anymore..but.. No carb should bind at all when hitting the gas pedal or by hand with the linkage at the carb.. is it possible one of those rods got bent a little when you took it apart?? It doesn't take much to bend those..maybe try and in hook the pedal linkage and see if the carb has free movement..if it does then maybe something from the pedal out is messed up.. if it doesn't then its the carb linkage itself..not knowing what type of carb you got will change things a little but most all carbs have little linkage bars on them that bend really easy.. maybe the pump you put in is suspect also..could be getting jammed up inside too..

Ya..what carby are we discussin here?
If it's an AFB/Edelbrock, it's possible you got the little "S" linkage on the acc pump upside down/flipped.
If it's a Quadrapuke, you may have put the roll pin in the wrong hole on the pump linkage arm, or may have slightly bent the carb tangs the linkage slips into to pivot on.
If it's a Holley.....ain't much you could do to screw that up, unless you put the spring on the wrong side of the diaphragm.

It is indeed a Edelbrock.....

Dan, if ya look at the "S" linkage, you'll notice that it is not completely flat, or straight. It has a slight bend in the middle. Hard to describe. In other words, if you lay it flat on a bench, it won't sit flat. If you flip the linkage around the wrong way, it can cause weird stuff to happen. If it is off-centered on the pump, it can bind a wee bit. Just a thought. Might not be the problem, but I've seen it happen many times on these things.

Dan, it's really more of a "bend toward the front, or bend toward the back" deal. The linkage itself is the same as far as which end goes up...it's how the bend in it is that matters. I would suggest just removing it, and turning it around. For instance, when you remove it, you'll have to move it either toward the carb, or away from the carb. Whichever way it comes out, just flip it around, and put it back the other way.
And yes, you'll need to remove the screw to do it.
Also, make sure your linkage from the throttle shaft is in the same hole as it was originally. There are three holes you can use, to change the geometry of the linkage, and pump output. Just use the same hole it was originally in.

I shall give it a try.....

The accelerator pump is only for adding a metered amount of fuel when accelerating from a stop, or while cruizing. It does not control the amount of fuel to the secondaries, or even the primaries...it simply adds an extra shot to overcome any leanness caused when opening the throttle. The position of the linkage on the lever(which hole it is in) changes the volume of fuel introduced at a specific throttle opening. The inner hole will give you a quicker shot, but for a shorter duration. The outer hole will give you a slower, steady shot throughout the throttle opening. Moving the linkage to different holes on the lever can help eliminate a "bog/stumble" on takeoff, depending on if the carb is putting too much, or too little fuel out.
I would first try to determine the exact reason for the bind, then play with the linkage in the 3 holes, to see which one gives the best overall gain. You can get it to where it feels great on takeoff, but bogs when trying to pass someone on the road...it's a balancing act.

Thanks Joel your diagnosis was spot on as always....I turned the 'S' clip around and the bind was gone.......

Isn't it great when things work out for a change? You gotta get ready for the show season, And you ARE going to Carlisle this year!

Carlisle is a real possibility for me this year. The gathering is still up in the air....trying to work out the distance, costs and transportation...

Some Steeler fans are ok as long as they realize who the class of the AFC North is! LOL   . I haven't heard about the Annapolis thing. Let me know the details. It sounds pretty good. You know, we both may have to keep an eye out for the Bengals!

Heres the all the info I have as of now.

That sounds cool, but I'd still like to see more details. This sounds like one you gotta register early because space will fill up quick!

Yup...start a new thread in this..I see there are 2 shows..ones a NCCC event that I'll probably be going to anyhow.. Is it June yet!! Glad the carb turned out ok... and... I always have an extinguisher by me when I work on cars... well .. I have a habit of finding leaking plug wires with brake clean.... Not good!!! glad most cars don't have wires anymore!!
