Husqvarna 137 Cylinder and Piston replacement

In this video, I show you how to replace a Husqvarna 137 cylinder and piston. This is the way I do it, but if you have a better way, please let me know in the comments. The reason for the scratches on the piston is that the chainsaw was running on an old fuel mixture. This mixture should not be older than 1 month.
