If you're careful, you can lift the whole engine out without it coming apart. There will be four metal spacer sleeves in the bottom plastic of the saw housing. Save those, you might need them.

It's been a while; I think you have to remove the muffler, the carburetor AND the carb adapter, and the flywheel to get the engine to slide out after you undo those four long bolts.
