Warning: Never run the engine in an enclosed area. Remove any combustible materials from the area. Wear eye protection and leather work gloves. Do not stand behind or in front of the vehicle while purging. Never go under the vehicle while it's inclined. The exhaust system can get extremely hot. Do not perform service on the spark arrestor while the system is hot. Allow components to cool sufficiently before proceeding.

Remove the arrestor clean-out plug from the bottom of the muffler

Quickly squeeze and release the throttle lever several times to purge carbon from the system

If carbon comes out of the exhaust, cover or plug the exhaust outlet(s). Wear protective gloves

Lightly tap on the exhaust pipe with a rubber mallet while repeating step 4
