You’re gonna need the super-duper extra heavy bar oil…
I think you need that on the shrinkage one first.
Buy a new cylinder/piston kit online or from Stihl. Easy to overhaul with a ring compressor kit for chainsaw motors. Done it a couple of times on my old 044 that I’ve run ragged. The first kit had piston breakage after a year of running, but the second kit has run smooth for 3 years. A Stihl kit is a little higher priced than the common online kit, but higher quality.
