7/32 screw does not exist, you probably have a 12-28(.216). Hens teeth.
Bartamos, Thank you. I went back and checked the old screws with my rather inexpensive mic and I come up with 0.219 -which is probably the 12-28 you mention. I understand that it is a metric, which I did not expect to find on a 1965 Rochester B carb. I am not familiar with 'hens teeth'.
