I need some opinions.
This is a buddies saw.
This is a TS420, but nearly same strato piston design as a 441.
I've ran some that had damage in smaller areas, and downward.
With a honing and tapering of the damage before a new piston kit, of course.
I know if the strato port has damage and leaks in the two transfer ports, it would not run well at all.
