Chainsaw Repair

thanks Andrew I bought a parts saw and got customer going. pm me a price if customer leaves parts here I might need it. My piston is 38 mm. @cut4fun I have not had a 4 bolt piston open to measure and now that I discovered how easy it is to drop big end bearings I am hesitant to open a good cylinder. Starting to think two bolt and four bolt engines are totally different engines. May learn more if I read that workshop manual one more time. Really lost on time fooling with 011.
