Spark Plug
Carbon deposits bridge the gap between the center and ground electrodes, creating a low-resistance path that prevents the high-voltage arc required for combustion. This fouling is often caused by stale fuel or an incorrect 50:1 oil mixture. Replacing the plug restores the air gap necessary for the spark to ignite the compressed fuel-air mixture.

Ignition Module
The ignition module's internal transformer windings and potting compounds degrade due to constant engine vibration and thermal cycles. This leads to an internal open circuit or a weakened magnetic field that cannot produce sufficient secondary voltage to jump the spark plug gap. A new module ensures consistent high-voltage delivery timed to the flywheel's magnets.

Spark Arrestor Screen
Over time, carbon soot accumulates on the fine mesh of the muffler's spark arrestor, physically blocking exhaust gases from exiting the cylinder. This backpressure prevents the scavenging process of the 2-cycle engine, making it impossible for the engine to start despite having a functional spark. Replacing or cleaning the screen restores proper volumetric efficiency.
