I kinda wonder if it would be possible to make a 2 stroke engine that doesn’t burn its own oil. Like, essentially supercharge it. Use an impeller on the flywheel to pump air into the cylinder so that the crankcase could be full of heavy oil. Though that might not work with a chainsaw since it has to be held at various angles.

This should explain why two strokes are the way they are, and how you can potentially mitigate some of the problems..
Since you don’t have a timing chain on a two stroke, you’d need something else to run a fuel pump.
If engine design interests you, there’s a lot of neat stuff in this channel.
That throws a “this video isn’t available anymore” page.
