Check it for compression first, then for spark, then dump out the old fuel, put straight gas in it, not premix, and then hit the " air filter " or screen with some starting fluid. That's not much in the way of time or money, it may start.
If it does not start, pull out the spark plug and inspect, if its soaked or caked, run it through a wire wheel and try it again.
If it does start, shut it down pretty quick, and drain out the fresh gas you just put in, and then put pre-mix back in it and run it.
Ive been playing this game for 20+ years on old two strokes. Straight gas acts kinda of like a solvent and seems to make it through the carb, and they seem to start easier and quicker on straight gas, but if you run it on straight gas, of course you will destroy it.
Ill be Ive bought well over 50- 2 stroke saws, and gas powered tools in the last 15 years at auction, most for under $15, and was able to get most running. Most common problem Ive seen on them is the fuel lines drying out and cracking, and leaking or no longer connected at all from shrinkage or drying out. On chain saws you have to take them apart to change the fuel line. I will always buy a chain saw at a sale if its cheap, but I will never buy certain brands, because they are junk new out of the box.
I picked a Homelite XL925 out of the back of a scrappers truck ( It was headed to the recyclers yard, he gave it to me for FREE), and I got it running with no parts, and sold it on Feebay for around $225 IIRC.
Good times !
