Specs At A Glance

Good To Know

Q: How can I tell if the ignition coil has failed? A: Symptoms include misfires, hard starting, rough idle, or a cylinder that will not fire, and testing the coil's resistance or spark output confirms the fault. Swap the coil to another cylinder to see if the problem follows it.

Q: Do I need to replace all coils at once? A: You can replace only the failed coil, though many owners service the full set at the same time for even ignition. Follow your machine's service information when deciding.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
