Small Engines (Lawn Mowers, etc.): How to remove the flywheel, engine model type, flywheel aluminum

Question
I have a 5Hp briggs & stratton MTD rear tine yard tiller. I need to replace the coil but the ground wire is going down behind the flywheel, I would like to get that flywheel off to further my investigation. any ideas?

Answer
What is the engine model, type and code number?  Is the flywheel aluminum or cast?  Have you removed the flywheel nut or starter cutch?  Are there any holes in/near the center of the flywheel?

Are you sure to coil is pad?  The wire running under the flywheel should go to the condenser.
Let me know.
