How to Replace the Air Cleaner Cover Assembly on a Troy-Bilt Trimmer

The air cleaner cover assembly consists of the air filter base, the choke-plate and lever, the air filter, and the air filter cover. The kit can be used to service tools with a broken choke, broken base, or a missing (or broken) cover.
