Official McCulloch gas leaf blower parts

Top McCulloch gas leaf blower parts that might need replacing

• Air filter. The air filter is an absorbent foam rectangle that's mounted on the air intake to the carburetor. It filters the air that enters the carburetor before it mixes with the fuel.
• Carburetor. The carburetor mixes air with fuel in the proper proportion to produce a combustible gas. That gas/air mixture then moves into the cylinder where it’s compressed by the piston and ignited by the spark plug.
• Fan assembly. The fan assembly is connected to the crankshaft of the engine on a gas leaf blower or the motor shaft of an electric leaf blower. The engine crankshaft or motor shaft rotates the fan blades to produce the air flow through the leaf 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.
• Recoil starter. The recoil starter is a starting system mounted to 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.

Replacing the carburetor on your McCulloch gas leaf blower

• In a well-ventilated area, remove the fuel cap and empty the fuel from the fuel tank into an approved storage container. To ensure that the leaf blower can’t start, disconnect the wire from the spark plug.
• Remove the screws from the air filter cover and then remove the air filter cover. Remove the carburetor mounting screws. Pull out the air box and release it from the carburetor throttle and choke lever. Note the configuration of the small and large fuel lines on the carburetor so you can reconnect them correctly later and then remove the fuel lines from the carburetor. Discard the carburetor.
• Push the fuel lines onto the proper connections on the carburetor. Insert the carburetor into the air box with the throttle and choke levers positioned properly. Position the carburetor on the side of the engine and reinstall the mounting screws. Position the air filter cover over the carburetor and secure it with the mounting screws.
• Reattach the spark plug wire to the spark plug.
