Leaf Blowers

Basically being a two cycle all you need to do is change the spark plug, air filter and clean the spark arrestor screen if your unit has one. Only other thing that would affect running that easily done is the cleaning and installation of carburetor kit in the carburetor with a re-tuning afterwords. I would only re-rebuild the carburetor if plug and air filter doesn't solve running issues; otherwords, if running good leave alone.
