Products Description
STL MS210/230/250/021/023/025 Ignition Coil
High-Performance Ignition Coil for STIHL Chainsaws
The ignition coil is a critical component of the electronic ignition system on STIHL 021, 023, 025, MS210, MS230, and MS250 chainsaws. This solid-state ignition module generates the high-voltage spark required to ignite the fuel-air mixture in the engine cylinder. When the flywheel magnet passes the coil, it induces a high-voltage current that travels through the spark plug lead to ignite the fuel. A failing ignition coil typically manifests as weak spark, intermittent starting, misfiring under load, or a complete no-start condition. This replacement coil is designed to OEM specifications for reliable, long-lasting performance in demanding cutting conditions.

FAQ
Q: How do I confirm this ignition coil fits my chainsaw?
A:Check your chainsaw model number on the housing. This coil fits STIHL 021, 023, 025, MS210, MS230, and MS250 models. It does NOT fit MS230C and MS250C models . Confirm your existing coil is square-type configuration (not round) before ordering .
Q: What are the symptoms of a faulty ignition coil?
A: Common symptoms include hard starting, weak or intermittent spark, engine misfiring under load, sudden stalling, or complete no-start condition. If the spark plug doesn't create sparks when tested, the ignition coil is likely defective and requires replacement .
Q: What is included with the ignition coil?
A: Standard packages include one ignition coil. Some kits also include a spark plug, air filter, and connection cables for a complete tune-up service . Check product specifications for exact contents.
