ISO a Jonsered 2159 fuel tank and wrap handle. I'd even take a Husqvarna version as long as it fits properly.
The Husky 359 tank will bolt right on and so will the 359 handlebar and brake guard. You will probably be able to find those easier and for less $$. Hope you get it going again, those are great saws!
Went to my local Jred dealer yesterday, 4 miles up the road. I got me a few parts. New tank, wrap handle, a couple AV springs, brake handle, decomp plug, and new B/C. Grand total of $190. She looks almost new again!
