Yeah title is all clear.
It's been a while since I've ran it but it should run with fresh gas and a new battery.
The only rust is small spots on the forks and muffler which you can see in the photos.
I'm not very motor wise so it might not need one it might just need the compression of the baffle to fix it's self. But it's on the top plate of the cylinder, I feel like it's an easy fix for anyone who is more mechanically inclined.
