[Rich Biebel]

Q-jet's made by Rochester had the part number stamped on the left side of the main body. Vertically if I recall right and were always the familiar bronze color.
The Carter manufactured Q-Jets were usually greyish in color and were usually a lot softer than a Rochester carb. Screw holes stripped out very easily and they were just a poor substitute for the Rochester.
I rebuilt lots of carbs in my garage days and never thought much of those carbs....
