Carburetor rebuild kit

The carburetor rebuild kit contains the essential components for rebuilding a carburetor, such as diaphragms, seals and gaskets.

Fan assembly

The fan assembly is connected to the crankshaft of the engine. The engine crankshaft rotates the fan blades to produce the air flow through the blower.

Fuel filter

The fuel filter attaches to the end of the fuel line inside the gas tank. It filters dirt and other particles from the fuel as gasoline moves from the fuel tank to the carburetor.

Fuel line

A fuel line is a flexible tube that carries fuel from the tank to the carburetor and from the primer bulb to the fuel system.

Primer bulb

The primer bulb removes air from the carburetor and fuel lines and fills them with fuel, so you can start the engine with fewer pulls on the starter rope. Activate the primer bulb by pressing it and allowing it to return to its original position.

Recoil starter

The recoil starter is a starter system on top of the engine that consists of a rope and spring-loaded pulley system. Pulling the starter rope rotates the spring-loaded pulley and spins the crankshaft to start the engine.

Spark plug

The spark plug ignites the air and fuel mixture in the engine of a gas-powered leaf blower.
