How to Rebuild a Chainsaw Engine

What happens here

This project provides verbose step-by-step instructions on how to rebuild a Stihl MS 500i chainsaw after it was damaged by incorrect fuel. The process involves completely disassembling the chainsaw's engine components, including removing covers, the bar and chain, throttle body, exhaust, handle, and ultimately the cylinder and piston. New parts (cylinder, piston, bearings, gaskets) are then prepared and installed, with emphasis on proper lubrication and torque specifications. The video concludes with the reassembled chainsaw starting successfully, and includes tips on proper break-in procedures and fuel usage.
