The right side is appropriately dirty/dry.
The left side is wet, dome cleaned by excess fuel. Left side is your rich problem.
Move pistons down and closely examine condition of cyl walls, look for scrape lines, or worn spots, like if the hone crosshatching is missing. Fuel can wash-off the protective glazing on cylinder walls, leading to aggressive ring/piston wear.
If these wear signs aren't there, you can save this by fixing the left carb rich condition.
Else, rehone and re-ring may be needed on left cylinder.
There is a trick to get original rings to reseat, but we'll save that for later...
