Foam vs Paper Filters
Some foam filters can be washed and oiled. Paper filters get replaced — do not try to wash them.
Signs of a Bad Filter
Hard starting, surging, loss of power in tall grass, or visible dirt packed in the element.
DIY Veteran Tips
I check the air filter every oil change. It takes two minutes and prevents bigger headaches.
Final Thoughts
Replace or clean the air filter before you assume carb or ignition problems. It is cheap insurance.
