I fixed my brother inlaws husqvarna with the same problem. The piston on his was melted worse than that though and needed replacing. I cleaned out the cylinder by making a wood plug out of a 2x4 about 3/16" or so smaller than the cyllinder bore. Then I cut a wedge out of the side of the plug so I could staple on a strip of the brown scotchbrite steel wool. Then I used that to hone the aluminum streaks out of the cylinder. I didn't remove the streaks all the way, just until they were barely visable. I found an aftermarket piston on fleabay for around $20-$30. That was about 3-4 years ago and the saw is still running strong.
