MUFFLERS

If your mower engine no longer sounds as it did when it was new, or it is overly loud, you more than likely need a new muffler. With small mowers that have one piece mufflers, it is to your advantage to purchase and replace the lawnmower muffler than try to clean or repair it. Replacing a lawn mower muffler is relatively simple. Be sure your lawnmower engine has been shut down and has had a cooling off period. Hot mufflers can cause severe burns.
Another cause of a poor running engine could be that your muffler is choked with carbon. If the muffler is able to come apart, you can remove the spark arrester and, with a soft wire brush) clean it and replace.
Mill Supply carries lawnmower mufflers that fit Briggs and Stratton, Clinton, Honda, John Deere, Kohler, Murray, Snapper, Tecumseh and Toro. By far the largest listing we have is for Briggs and Stratton with a listing of over 20 different styles. Each type is pictured with a clear application description. Briggs and Stratton is one of the most popular engines used on mowers in the past and present.
