I stopped by my Stihl dealership this morning to order a piston for a BG 56C Stihl leaf blower that has been straight gassed. No aftermarket pistons are made to my knowledge for this machine. The mechanic told me I am spinning my wheels cleaning the cylinder and replacing piston/rings because when a 2 cycle is straight-gassed it "swells" the cylinder making it unusable. After rebuilding over 30 saws last year with scored pistons/cylinders....I laughed and asked him if this was the company response in order to sell piston & cylinder sets instead of individual components. He got a little peeved and said he was taught this in "tech school". Has anyone ever seen or heard of a "swelled cylinder" ?
