Overview:
This is a Genuine Stihl ignition module (part no. 1139 400 1311) for petrol chainsaws, providing the spark and timing needed for reliable running. Built for the Stihl MS 181 and MS 181 C, it replaces the original coil like-for-like to restore dependable starting, smooth idle, and consistent power. The module uses a robust, moulded polymer housing with epoxy-potted windings and a steel core to withstand heat, vibration, and moisture in typical forestry and garden workloads. A straight connector tag aids neat routing and an accurate fit within the housing. Suitable for routine maintenance or a repair when the existing coil becomes weak or intermittent, it helps ensure your saw remains easy to start and ready for work.
