Frequently Asked Questions
What is a Lawn Mower Stutter?
A lawn mower stutter is a temporary loss of power or RPMs, often accompanied by a jerky or irregular motion. This can be caused by various factors, including air filter issues, clogged fuel filters, or worn-out spark plugs. Stutters can be a normal occurrence, but repeated or severe instances may indicate a more serious problem.
How do I diagnose the cause of my lawn mower stutter?
Start by checking the air filter and fuel filter for any blockages or debris. Next, inspect the spark plug for signs of wear or fouling.
