I recently rebuilt the 2 Bbl carb on my Starfire. It is not original (# does not match book) but is for a 231 v6. I am not worried all that much about originality with this car. The reason I rebuilt it was that on acceleration, it had a "dead spot" just off idle where the engine would literally cut out completely. If I pushed the pedal past that point the engine would increase in speed, but you could feel that something was not right in the way it almost fought against accelerating. So, I rebuilt it, and it performs much better now. However, during rebuilding I came across a part of the carb that I was unsure of its purpose, and also unsure if all the parts were there. That part is shown in the picture. The rebuilding guide mentioned that there would be parts under the cover (held down by two screws), but there were none under the cover on my carb. Does anybody know if these pictures are missing anything?
Thanks.
