Product Description

Installation Notes

Installation is typically performed by a small engine technician or qualified power equipment mechanic. Before servicing the ignition module or any associated fasteners, disconnect the spark plug wire to eliminate any risk of accidental engine start. Use the correct hand tool for the fastener drive type to avoid stripping the head or damaging the module housing. Do not overtighten, as the ignition module housing and mounting threads can be damaged by excessive force.
