While it is very likely that each model in that series has a different size nozzle, I don't think you would really need to worry about it as the differences will be minimal.
I know of people running 029 sized jetted carbs with 039 top ends.....no issues.
If you feel you have a fuel starvation issue, you could just raise the metering lever a tad, but I doubt you will see a difference.
