Default correctjetting for carter WCFB 2626s and2627s

I'm wondering how i can check if my carburetors have the correct jets

according to my documentation, main jets should be .0935" for the primary and .053" for the secondary
idle jet should be .031"and metering rod .077"x.071"x.068"

On the idle jet, i can read 3025, on the primary main jet 120-392
the secondary main jets have no mark
metering rods are stamped 1350

You guys are a wealth of information, just there for the asking . . . so I'm asking: How about correct factor jet size for a Carter AFB 3269S for a 1962 327/300hp 4-Speed? I realize today's gasoline may require different jetting - any suggestions there as to what would work best? I replaced the Edelbrock carb on the car with a correct Carter AFB, and while she starts and runs OK, she's a little rougher than I think she should be. Thanks!

Danchuck 55-57 Chevy Parts has them.
I would get the metering rod springs too unless you are sure those are the right ones.

I believe the jets for Carter or Edelbrock carbs will work. They might be marked differently but it would just be a matter of getting the correct size instead of looking up a number.

I picked up some Edelbrock jets for my WCFB'S some time back, and they are interchangeable. I used drill bits as a gauge to size them correctly.
