Dalom Ignition Coil Module for Stihl 021 023 MS210 MS230 MS250 - Square Mount, Restores Spark

Dalom MS250 Ignition Coil Module is a direct-replacement magneto that restores spark performance for compatible Stihl 021, 023, MS210, MS230 and MS250 chainsaws.

If your Stihl chainsaw suffers from weak or intermittent ignition, this Dalom ignition coil module is designed as a practical replacement part to get your engine firing consistently again. The module matches the square-type mounting and terminal layout used by a range of mid-size Stihl two-stroke saws, and it ships as a single unit ready for installation. It is sold with a short-term return policy and is intended for users comfortable with basic small-engine maintenance.

How will this ignition coil improve my saw's starting and running?

Replacing a faulty coil restores high-voltage spark output to the spark plug, which directly affects starting reliability and steady idle. A healthy coil helps eliminate misfires and rough running caused by weak or no spark, allowing the engine to reach and hold RPM more predictably.

• Restores proper spark strength for quicker starts
• Reduces stalls and misfires under load
• Compatible with specific Stihl models noted for correct fit

Which Stihl models does this Dalom coil fit and what should I check before ordering?

This coil fits Stihl model numbers 021, 023, MS210, MS230 and MS250 that use a square-type ignition coil. Before purchase, confirm your saw uses the square coil pattern and compare mounting hole spacing and plug lead orientation to ensure compatibility.
