1. Ran a compression test on cylinder found to be low put oil in cylinder reading was high until oil leaked out.
2. Took apart engine removed cylinder head found it to be scored. When on in to eReplacement parts ordered parts.
3. Installed new head gasket, removed old piston had to reuse piston rod keepers on new piston repla ced piston put piston ring in groove only can go one way compressed ring with mini ring compressor (can be done by fingers also). Reassembled cylinder head to engine torqued all bolts. Added a little two cycle oil in spark plug opening. Pulled gently on recoil fifteen or more times to start setting piston and ring to the new cylinder walls. Added mix and started saw blipped saw so it would idle. Best to keep a low no load speed until five tank fulls of fuel. It is okay to run it hard on a load during the break in time. Let saw cool rechecked torque. Cut half a core of wood saw is working fine.
