On the spark plug, do not touch any part of metal or you shall suffer from a zap.

When you are successful in removing the nut, you need a crowbar to remove the flywheel. Once the flywheel is removed, you should put it somewhere secure, and when placing the flywheel to its original position, the key must be in the correct direction.

Piston Removal

Once you cut the piston off the crankshaft, you can force the piston from the burning chamber to check whether the gaps between the rings align or not. In case you see some errors, you might want to replace the old piston rings with the new ones. Remember to add a little engine oils so that they can function properly.
