Carburetor Assembly
The pilot and main jets in this carburetor are highly susceptible to varnish and ethanol-induced corrosion. This blockage prevents the fuel-air mixture from reaching the combustion chamber during the intake stroke. Replacing the assembly is the most effective resolution as internal passages are often too narrow to clean reliably.

Spark Plug
Carbon deposits on the insulator nose can create a conductive path that prevents the electrical charge from jumping the gap. This shunt path effectively grounds the plug before ignition can occur. A new plug ensures the dielectric strength is sufficient to generate a high-intensity spark.

Ignition Coil
Thermal stress or internal insulation breakdown within the secondary windings can lead to an open circuit or weak magnetic induction. Without a consistent high-voltage pulse delivered to the spark plug terminal, the engine will fail to achieve combustion regardless of fuel state. This part restores the necessary electrical potential for ignition.
