Oh boy. Did you post that cylinder wall pic before? I don't remember seeing it. I would have suggested pulling the engine and at least honing that cylinder if not something more drastic, plus rings on it at a minimum. Maybe the rings are just stuck and it'll work itself out but I'm not hopeful.
See that a lot with small engines, especially cheap weed whackers and stuff that have crappy air filters. Chunk of dirt or carbon gets in there, scores the cylinder and rings and you end up with very little compression.
There is an old trick, back in the day guys would free up stuck rings by dribbling ATF down the carb while the engine was running. Sometimes it would help. You could dry sea foaming it too through a vacuum line, let it suck a bottle in and see if it does anything. Another trick was to pour small amounts of Comet kitchen cleaner powder in while it was running (new engine) and that would help seat the rings.
