How to fix your Poulan 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.

Top Poulan 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.
