In the late 70's I purchased my 162SE. It has been a great saw and starts and runs fine, but like me, is getting a little tired. I have been looking for a piston/cylinder/gasket kit, but can't find anything OEM or European. (Dukes, HL Supply, Saw Salvage) There seems to be several Ebay Chinese options including oversize available. I would like to refresh the top end, but don't want to make things worse and unreliable. Is there a quality Chinese option or am I just out-of-luck trying the clean up a 45 year old saw? Thanks for any advice.
