Block the end of the muffler with a shop rag and start engine. Momentarily
increase engine RPM several times to purge accumulated carbon out of the
muffler. Stop engine and allow muffler to cool.
Never run engine in an enclosed area. Never perform this operation
immediately after the engine has been run because exhaust system is very
hot. Make sure that there are no combustible materials in the area. Wear eye
protection and gloves. Never stand behind the vehicle while purging exhaust
system. Respect all applicable laws and regulations.
