Interesting thread.
I'd do this:
- in your head, write offf the Stihl.
- now that it has no value, strip it down and try to fix it. There's a couple of good youtubes on that
- chances are it's just the carburettor - in which case a few quid, a replacement, reassemble and you feel like a minor deity. Plus, bonus, you have a perfect, still good, good (Stihl), chainsaw.
- if your strip down goes like mine and you lose bits, break bits, can't reassemble bits or can't find a fault, then you're no worse off - just buy the replacement
