Small Engines (Lawn Mowers, etc.): Snapper Riding Mower, briggs and stratton, hp briggs

Question
I have a 6.5 HP Briggs and Stratton engine that is ruined due to something getting into the cylinder and scoring it very deep. I need to remove the drive disk from the engine shaft.The engine is removed and I can see two allen set screws on the disk hub just above the belt pully also I can see what looks like some threads at the bottom center of the disk. What is the best way to remove the disk. The hub is on the engine shaft with a key. Is the drive disk and pully all in one piece? Thank you,B.J.Mongan

Answer
 Hello BJ:

 Depending on the Model of the Mower, Some Are One Piece and Sone Are Not. Send me the Model Numbers Off the Mower Frame, Please. There Are Different Styles of  Assemblies Like you have Described. With the Mower Model Numbers(not the engine) I can See the Diagram of the Mower and Better Assist you. Thanks.

 Respectfully

 John
