This genuine Stihl ignition module is a direct replacement for OEM No. 4140 400 1313, engineered for small two‐stroke engines used in brushcutters and hedge trimmers such as the FS38 and FS45. The module houses copper windings in a tough, epoxy‐potted body with a steel laminate core, giving strong resistance to heat, vibration, and moisture. It generates a consistent, timed spark from the flywheel magnets to ensure dependable starting, stable idling, and smooth running across the rev range. Designed to match factory specifications, it maintains correct ignition timing and electrical characteristics for the listed machines. It supersedes earlier Stihl references 4140 400 1311 and 4140 400 1309. A practical choice for routine maintenance or repair, it restores reliable ignition performance on compatible Stihl equipment. Genuine Stihl part.
