Acquired blown 2 saws
Can't really find a reasonable option to rebuild them

Any suggestion ?

 

What's wrong with them?

 

Appear both to have scorn cylinders and piston shot

 

Assuming "blown" means scored, you can usually get away with cleaning up the cylinders and replacing the piston. There are aftermarket pistons available for both on eBay.

 

You'll need to figure out what caused them to score, but fixing these isn't an issue.

 

Cylinder are shot I think !

 

The guys probably put straight gas in them

 

You might be surprised what can be made serviceable. Let's see some pics.

 

Have even thought about tearing down
