HURI Ignition Coil

A failing ignition coil typically manifests as a chainsaw that refuses to start, stalls frequently once the engine warms up, or runs with a noticeable misfire. If you have already ruled out fuel issues and verified the spark plug is clean, the coil is often the culprit behind erratic engine behavior.

No, this ignition coil is designed specifically for models that utilize OEM part numbers 530039143, 545199901, 545063901, and 530039239. Always check your chainsaw's manual or the existing part number on your current coil to ensure a direct match before purchasing.

The included spark plug is intended to match the specifications of the chainsaw models compatible with this ignition coil. However, it is always best practice to verify that the plug's heat range and gap settings align with your specific chainsaw's requirements as noted in your owner's manual.

The installation is straightforward and generally requires only standard hand tools, such as a screwdriver and a socket wrench set, to remove the chainsaw housing and secure the new coil. You will need to ensure the air gap between the coil and the flywheel is set correctly during installation to ensure a strong spark.

Replacing both components simultaneously ensures that your ignition system is fully refreshed. Since a faulty coil can sometimes damage a spark plug and vice versa, performing a complete tune-up eliminates the risk of a new coil failing prematurely due to an old, worn-out plug.
