How to Rebuild a Chainsaw Engine
What happens here
Unbox the new cylinder kit from Stihl, which includes a shiny new cylinder with a pre-installed piston, piston rings, a wrist pin, and retainer clips. Also included is a new head gasket and a compression release delete plug. The creator notes that his previous attempts at obtaining a piston ring compressor (Duralast brand) and a long T27 Torx bit set were based on incorrect torque specifications (126 ft-lbs instead of 12.6 ft-lbs). He plans to use these new parts to replace the damaged components.
Goal: Prepare new parts for installation.
