It is the whole assembly containing the pull start (if applicable) or the metal or plastic shroud surrounding the flywheel (it spins when you start the engine ).

It requires a special puller.
No. It positions the flywheel in the proper place for the ignition timing.

The coil is under the cowling on top of the motor where the flywheel is.
There is no way to adjust the timing on a 17.5 Briggs engine. The magnet is on the side of the flywheel and there is only one way the flywheel can line up. All you can do is make wure that the coil is gapped correctly.
Most people use a standard business card between the magnetto and flywheel.
If you know your part number of even model number, you can go to eReplacementParts.com for the Briggs and Stratton parts your looking for. The site features part lists for each engine or motor and includes thousands of detailed diagrams to help you replace the flywheel once you get it.

For most Briggs and Stratton engines the charging system is under the flywheel. You will have to remove all the shields that cover the top of the engine and the flywheel and then remove the flywheel itself. Once the flywheel is off the stator is exposed. Depending on what model you have there will be a series of screws that hold it to the block. Just unplug the wire connector and remove the screws and it will come off with a little wiggling. Make sure that all the magnets on the bottom side of the flywheel are in place and secure or replacing the stator will not do you any good.

On a 19.5 hp Briggs & Stratton engine, the points are typically located under the flywheel, which is situated at the top of the engine. To access the points, you will need to remove the flywheel and possibly the ignition coil. The points are part of the ignition system, responsible for opening and closing the electrical circuit that ignites the fuel-air mixture in the engine. It's important to consult the engine's service manual for specific details and procedures related to your engine model.
The timing is not adjustable. The only way the engine can be out of time is if the keyway between the crankshaft and the flywheel is sheared. If it is in place and in good shape the engine will be in time.
