Review on Stens 500 736 Piston Rings Black by Shaylon Bateson

Cylinder honed and assembled the old Kohler K301 engine. I only got a little over 90 pounds of compression on the first read. Every time I start the engine and let it run, my readings get a little bit better. Now I'm at 120. I recently overhauled a B&S two cylinder engine and got 140 and 180 out of those cylinders pretty quickly. These rings take a lot longer to set.
