If you dont KNOW why your piston or cylinder was damaged the first time, dont just replace it or the same thing will happen, these parts die for a reason. The most common reasons for scoring are bad fuel, improperly adjusted carburetors, and air leaks.
We are an internet only, father and son business. My hobby is rebuilding pro Stihl chainsaws. I know a fair amount the modern Stihl saws and dont mind answering questions when I can help.I know very little about other brands of chainsaws, most of the parts for other saws that we stock are requests from good customers, I will answer questions if I can but will also tell you if I dont know the answer. And may be able to direct you to a good source of info or another merchant who can better meet your needs. We do NOT work on saws for customers.
