Leaf Blower: Excessive vibration

A damaged fan blade can cause a leaf blower to vibrate excessively; replace the fan blade if it’s cracked or damaged.

An engine problem can also make a leaf blower vibrate too much. Do preventive maintenance on the leaf blower to keep the engine running smoothly.

If the engine still runs rough after preventive maintenance, a dirty carburetor could be causing the engine to sputter. A partially clogged jet in the carburetor may be preventing the right amount of fuel from reaching the engine cylinder. Rebuild or replace the carburetor if the engine sputters and vibrates.

These repairs may help solve your Leaf Blower problem:

Replace the leaf blower fan blade

Fan assembly

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.
