I finally got around to modding the muffler on my Husky 55. When I pulled the muff, the look of the piston scared me a bit. It looked badly scored. Anyway I pulled the jug, and the problem was carbon build-up on the exhaust port.
I was out of penetrant, so I used some Break Free CLP, which is an all purpose firearm cleaner/lube/preservative. I just sprayed and waited about an hour. It cleaned up really easily with a wire cup on a dremel tool. This is what I will use from now on!
The piston and rings didn't turn out to be so bad after all. all of the scoring came off the piston easily with some 320/600 wet/dry, and even the ring just needed the carbon ridges removed top and bottom and a light touch with the wet and dry. I removed the baffles, hogged out the outlet some, and removed the tabs that obstruct the deflector..that seems to be enough.
Just wanted to share about the CLP.
