Tools Used:
Pliers, Power Drill, Socket set, Adjustable Wrench
Flywheel cracked and sheared flywheel key
Initial problem was a Briggs and Stratton 5HP lawn mower motor not turning over to start:
1. Initial idea was to take apart and clean carburetor which did not change status.
2. Removed engine covers and casing.
3. Removed Flywheel cup by gripping with a wrench just above blade under lawnmower and loosening bolt on top with socket (had to to go purchase 15/16th inch socket as this was just above the biggest in my set).
4. After visual inspection determined a crack was in flywheel.
5. Ordered parts (don't forget to order flywheel key and flywheel puller as these do not come with it).
6. Used flywheel puller to remove flywheel.
7. Placed new flywheel on mower and inserted flywheel key.
8. Replaced flywheel cup and engine covers.

My repair was a bit more extensive as I also removed valve and piston covers to clean engine build up as the valve was sticking due to this build up and I also sharpened the blade.

Engine runs like new now.
