Gurtner AR2-10 737 vs AR2-12 873 carbs

Does anyone on here have a solid knowledge of the Gurtner AR2-10 737 and/or the AR2-12 873 carbs? I have both carbs and only just now realized that they are not the same. I have a few basic questions for someone who knows these two carbs (and where they overlap and where they differ).

Yes, I know Gurtner carbs are horrible and yes, I know I should get a Dellorto. For now, humor me. I'm hoping to go with this stock carb.

Yup! That’s how I realized that the carbs are stamped with model/date info. Now I have some questions about reassembling my AR2-10. I’m hoping someone here knows a lot about these two carbs.
