Start Here: Identify Any Small Engine Problem
If your small engine won’t start, runs rough, smokes, loses power, vibrates, or behaves unpredictably, this page will help you pinpoint the symptom and understand what it usually means.
Choose the category that best matches what you’re experiencing.
How to Use This Site

Runs Rough, or
Power Loss.
