not sure if your carter is like the edelbrock, but id say that your fuel level is to low. a edelbrock will do that, and it doesnt take much to cause it. maybe only a 1/16 or so on the float adjustment, so try raising your float level a little at a time. you my have to do this a couple of times to get it right.
thanks for the suggestion Paul. I had a feeling it was a float level issue. It's really the only thing that I adjusted during the rebuild. Of course, I adjusted to the OEM specs. Apparently, that isn't what I need!
I really just need to get this thing running well enough to get it a friends house so I can swap it out for a MC 2100 carb.

When you take the lid off the top (it's held on by 3 flat-blade screws) there are two arms inside that pivot around an axis and they have screw adjusters on them to dictate when the accelerator pump engages. It is ABSOLUTELY CRUCIAL that those are adjusted properly or you will have a terrible flat spot, as you noted. It took me many trial runs down the road with that little lid off and making periodic adjustments to get it just right. I mentioned this in your other thread, but you really need a manual, like Chilton's, to be able to adjust it properly because it shows some pictures. They're only about $13, but well worth that if you do your own work.

I dont know what vehicle you have but I had a Carter carb and well didnt have much luck. Depending on what you wanna deal with. I actually had given up and replaced it with a Autozone or Advance carb, dumb idea. made things worse...
Well anyway I went out anf bought a weber carb from 4wd.com, I tell you what it made a huge difference!!! The big thing is that it eliminates the emissions so if your state requires it sorry but you might be out of luck. If you can try it, I actually use less gas and better performance.
