I want to make a small internal combustion engine. A bore of maybe 1" to give you an idea of the scale. I've made several models in Solidworks and 3D printed them before, so I'm familiar with the construction of all the moving parts.
But is there any recommended reading on construction of a carburetor? I understand how they work, that's not what I'm talking about. I mean given the displacement of my engine, is there a simple way to calculate an optimal diameter for the carb bore and fuel nozzle?

So a 5 horse briggs

Home shop machinist forums and model aircraft forums would be good sources of information. The bore you want is similar to some larger engines for model aircraft. Copy their carbs.

maybe just buy a cheap one meant for a 100-200cc engine and adapt it?

Far too large.
The point of machining such an engine is to perform the lathe and millwork, and the additional work to make very simple carbs is minimal but a good student project.
What OP wants to do has been done since before the internal combustion engine was invented. Small live steam models have been made as prototypes, patent models, and for fun.
It's a fair-sized hobby. It has forums. This is not one of those forums so OP is best off using a search engine, learning relevant terms, then using that search engine more effectively.
Here are a couple. Now GTFO and have some very enjoyable reading! There are all sorts of projects from simple to insane.

BTW if OP image searches "model aircraft engine carburetor" there are plenty of examples. Next step is sizing and choosing a design or designs as inspiration.
