Simplicity/Allis CCKB 20 HP Engine. Completely Rebuilt. It's broke in and has 20 hrs. of runtime. Has new Standard main bearings, rod bearing and standard pistons and rings. All new gaskets. Includes Flywheel and working stator, carb, and starter but doesn't include muffler or front PTO as shown in pic. Runs excellent so if interested I have a video of it running that I can send to your email upon request. Can hear it run? Any more questions give a call. Thanks For Looking.
