Getting my Weber 45dcoe on my 13b to idle correctly

What idle jets and fuel jet sizes do I need to get my Rx7 to idle and accelerate firmly with power!
It’s a 13b used to be fuel injection, did a carb swap with 12a components but 13b housings
at the moment with the stock Weber I bought car runs but not great

I generally start with a 65F9, though YMMV with stock ports.
