Stihl 031 AV chainsaw? I have a stihl 031 av chainsaw that i found out within...

I have a stihl 031 av chainsaw that i found out within my shed i put in nearby back contained by the early 90s. I be wondering if this was a apposite saw. It starts and runs perfect, great compression. I be wondering what type of piston rings and cyclinder wall they put in the entity stock. It was one of the final years that they made them in germany. Thank you.
Answers:    If it runs and works great, don't mess next to it. The cylinder with the piston and the rings is still available, but cost over $300. You hold a great saw. That design has enduring power, as long as it is taken care of. The equivalent saw produced in a minute is the MS310, but I would take your 031 within a heartbeat.
a great saw i have 3 not sure in the region of the rings or wall
