Champion Spark Plug (RDJ7Y). The spark plug ignites the fuel and air mixture in the engine's cylinder to power the engine. If the spark plug is has fouled (if the tip of the spark plug is burnt or damaged), the engine may not start or may run rough.
Fuel filter & fuel line kit. If the fuel filter and fuel line are clogged, they will restrict the flow of fuel to the carburetor. As a result, the engine may not start.
Fuel line. The fuel line allows fuel to travel from the fuel tank to the carburetor and from the primer bulb to the fuel system. If the fuel line is leaking, replace it.
Small engine primer bulb with hose, large diameter. If the engine does not start the primer bulb may be defective and unable to draw additional fuel in to the carburetor to assist with starting the engine.
