140/140 is used by weber as baseline jetting for the 32/36. Same baseline is used for stock or worked engines. It's only a beginning as tuning is an iterative process, repeatedly changing the jetting until the ratio gets more and more fine tuned.

Yes, I mean the main jets. But the air jets are just as important as they control the air/fuel ratio in combination with the main fuel jets.
