This is a replacement O.S. Cylinder & Piston Assembly for the O.S. 21TM engine.

NOTE: You will need to detach the old connecting rod and re-attach it to the new piston/sleeve during replacement. We recommend that when you replace the piston/sleeve on any engine, you also change the connecting rod and wrist pin clips.
