She’s not real pretty, but she’s a runner for a 45cc saw!
Run with what you got for now, we all did.
When your ready to buy look local for a cheap 192 or 3. Many of us have piles of the old stuff if you want any of those Stihl 020AV and AVE's. I still have a rear handle of the APV or something it was called. Some more 192's and a like. You like 009 or 009L? Overlooked most times by climbers but dependable and cheap saws that can do top or ground work. Mid handle type.
When you do dig *s-word up, if it lacks parts support and is a running cheap saw just plan on using it as a backup.
You can get carbs, lines, starters, handles, bars, chains, sprockets/drums and rims for just about anything used or new. The tough stuff is pistons, cranks, air filters, coils/flywheels and other large parts may be gone now or only available used by mail order. Check the parts stream before making a large investment in any saw. Check the known issues and decide if your willing to deal with them. Any MS020 or 20xT is tops for most of us. Modded ones are nasty and rarely needed.
Some, in time will sit on a shelf. Cheap deals rarely depreciate in value but make good trade fodder. Let us know what you dig up. Many collectors floating around who want stuff we would never use for working.
