Just rebuilt this Rochester dual jet 210 on my son 79 cutlass supreme. I have the same carburetor on my 82 Buick regal 3.8L V6. My son has a 260 4.3L V8 rebuilt the carb and fine tuned it and it runs on it own… it’s my son first car so I showing him the ropes that I learn my self.. car it self going need a lots of potential all we’re trying to do is make sure this car move forward and backwards so next I’m about to check if the wheel move on his own I gonna put the car on Jack stands in the rear and chalk the front wheels and put it in reverse and drive see if the wheels spin.. but for right now step at a time.

What is this gap hole on this part for? Do it make a difference or should I keep the original one? This go down inside the bowl area on the carburetor.. I rebuilt my other carb but this kit came with this piece that’s is different.. currently rebuilding the carb for my son cutlass.. thanks!
