50mm Piston Kit Fits Husqvarna 268 501659403

A 50mm piston kit for the Husqvarna 268 chainsaw. It replaces 501659403. A scored piston is usually a lean condition, so pressure and vacuum test the crankcase and fix any air leak or fuel fault before the new piston goes in. Check the cylinder for scoring and aluminum transfer, use a ring compressor, fit the circlips fully and check the carburetor tune.
