Official Mantis gas leaf blower parts

Common replacement parts for Mantis gas leaf blowers

• 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.
• 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.
• 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.

How to fix your Mantis gas leaf blower when it smokes

Mixing too much 2-cycle oil with the gas can cause excessive smoke from the leaf blower's engine; follow the guidelines in your owner's manual for mixing the fuel and 2-cycle oil. Most leaf blower engines use a 40:1 ratio of gas to 2-cycle oil. To achieve that mix, add a 3.2-oz bottle of 2-cycle engine oil to 1 gallon of gas.

A dirty air filter also can lead to engine smoke. If the filter prevents the carburetor from getting enough air to create the right fuel/air mixture. A fuel-rich mixture can cause the engine to smoke. Clean the air filter and perform preventive maintenance on the leaf blower to help prevent engine smoking.

Clogged jets inside the carburetor also cause excessive smoking because the carburetor can't mix the right amount of air with fuel. If the engine still smokes after completing preventive maintenance (which includes cleaning the air filter), you may need to rebuild or replace the leaf blower's carburetor.
