Replacing the stator is simple enough. You need to move/remove items which are in the way such as the pipes, hoses, etc.. You need to remove the recoil starter, remove the flywheel, disconnect the stator wires, remove the stator screws and then reverse the process. You will need a puller to remove the flywheel, don't try prying it off. When you install the flywheel, put a small amount of antisieze compound on teh crankshaft. This will make it easier to remove the next time. Take you time, should go smoothly for you.
