FAQ

This coil is listed for Stihl chainsaws including 020, 020T, 021, 023, 025, MS210, MS230, and MS250. Some references also associate these part numbers with certain MS200 and MS200T applications, but those saws can vary by build and ignition setup, so it is best to match your original coil number before ordering.
It replaces Stihl part numbers 1123-400-1301 and 0000-400-1306.
Common symptoms include no spark at the plug, hard starting, a saw that starts and then dies once warm, intermittent misfire, or a complete no-start condition even after replacing the spark plug and using fresh fuel. Before condemning the coil, also check the stop-switch wire for a short to ground and inspect the spark plug, plug boot, and flywheel area.
Installation is usually a moderate DIY repair. On most MS210, MS230, MS250, 021, 023, and 025 saws, access involves removing the top cover and starter housing, disconnecting the kill wire, removing the old coil, and setting the new coil air gap to the flywheel magnets before tightening the mounting screws. Typical install time is about 20 to 45 minutes.
Most repairs need basic hand tools such as a Torx driver or screwdriver set, a socket or nut driver, and a thin non-magnetic spacer to set the coil gap. Many people use a business card as the air-gap spacer between the flywheel magnets and the coil legs during installation.
Yes. Inspect the flywheel magnets for rust or debris, make sure the kill-switch wire insulation is not rubbed through, and verify the spark plug and boot are in good condition. If the saw still has no spark after coil replacement, recheck the air gap, confirm the stop switch is not grounding the coil, and make sure the flywheel key is intact.
Ignition coils often fail from heat cycling, vibration, moisture intrusion, damaged plug leads, or chafed kill wires that create electrical faults. On older saws, repeated hot-cold operation and long-term exposure to sawdust and oil residue around the flywheel can also contribute to ignition problems.
