A blower housing, a starter cup (which may come with the pull-starter assy.), a flywheel screen, possibly a spacer plate under the cup, not sure what else or which particular items you could use for this model engine.
Suggest you contact a B&S Central distributor, ask for tech-serv. or navigate the menu system. If you aren't sure who that is, see their US map, page 2 has the listings.
