My knowledge is regular car engines. On a typical combustion engine, you don’t want oil spraying or leaking into the combustion chamber as you would develop carbon deposits and degradation of performance.
How do these mix engines work both from a function aspect (lubricating via the gas) and maintenance (not building up catastrophic amounts of carbon)?

Two stroke engines use a different type of bearing usually ball or needle bearings. It doesn’t require as much lubrication as an oil bearing which requires constant oil pressure. So having a small amount flowing through the air is enough to cool and lubricate the engine. The oil is specifically formulated not to create excessive deposits and to burn well. It also lubricates the cylinder walls on top and bottom of the piston so that helps with lubrication.
