Stihl BR-600 Magnum? Backpack Blower for parts

Description

I buy used chainsaws wherever I can find them and I sell them here. But sometimes I end up with blowers and I have to get rid of them. The blowers that I sell are used, usually abused and probably don't run. When I say a blower pops it means I have poured fuel in the carburetor or cylinder and it runs for a few seconds as it uses up the fuel.
This blower makes spark. Compression is so low it doesn't register on my tester. It makes noises when pulled, hard to describe, klunking is the best I can come up with. I believe it was taken apart for a diagnoses then re-assembled. It is missing 1 screw from the front cover, the choke knob and the primer bulb, could be missing other parts. The front cover has a Magnum sticker but it doesn't say that on any of the other tags. The back board is cracked.  There is a piece broken off the bottom. The pipes will be taken apart for shipping. It is dirty and has been sitting possibly outside.

I do not take returns, I describe the blowers to the best of my abilities and it is possible that I missed something but it is usually small like a missing screw or something. These blowers are old and could have other problems I did not even check for. A common problem is bad fuel lines.
