Description
Overview:
This ignition module is a Genuine Husqvarna OEM part for mid‐range petrol chainsaws, including the Husqvarna 435 and 450. It is an encapsulated electronic coil with a laminated steel core and a tough, moulded housing designed to withstand heat, vibration, and moisture in outdoor use. Working with the flywheel magnet, it generates and times the spark for reliable starting and steady running. Use it to restore correct ignition performance where starting has become difficult, the spark is weak or intermittent, or the engine cuts out at idle. Built to Husqvarna's specification, it fits the intended mounting points and connections on compatible saws without modification, helping maintain factory performance and compliance. Suitable for both professional users and DIY owners who want dependable spark and consistent engine behaviour.
