Why does a leaf blower vibrate excessively?

Replace the leaf blower fan blade

The leaf blower's fan blade is attached to the engine shaft and moves air through the blower tube. A damaged fan blade causes the leaf blower to vibrate excessively. Replace the fan blade if it's damaged and vibrating.

Do leaf blower preventive maintenance

Proper maintenance ensures that your leaf blower runs smoothly and works properly. Refer to your owner's manual for guidance in maintaining the leaf blower. Replace parts such as the air filter, fuel filter and spark plug.

Replace the leaf blower carburetor

The leaf blower's carburetor mixes air and gasoline in the proper proportions to create a combustible gas. If the engine starts and then sputters, or doesn't start at all due to lack of fuel, you might need to replace carburetor. It's often more cost effective and practical to replace the carburetor rather than rebuild it.

Rebuild the leaf blower carburetor

The leaf blower carburetor mixes air and gasoline in the proper proportions to create a combustible gas. If the engine starts and then sputters, or doesn't start at all due to lack of fuel, you can rebuild the carburetor. Rebuild kits are available for most carburetors and contain essential components for rebuilding a leaf blower carburetor, such as diaphragms, seals and gaskets. You can sometimes fix a fuel supply problem by dismantling and cleaning a carburetor. Use the kit to rebuild the carburetor after cleaning it.
