Gas-Powered Leaf Blower Troubleshooting

A gas-powered leaf blower can come in handy for fall lawn maintenance when you’re trying to clean dead leaves off grassy areas. However, they can develop a number problems. If you need to troubleshoot your gas-powered leaf blower, start with the areas below.

Fuel Source

Is your leaf blower hesitating or not starting? Make sure you have the right fuel in the fuel source. You should use a mixture of gas and oil; proportions will vary, based on the manufacturer. The tank should be full of this mixture.


The impeller is the fan that blows air out through the hose to blow the leaves away. If it’s jammed or not working, you won’t get any air, just a loud machine that does nothing. The unit may jiggle back and forth if you check it (while it’s turned off, please!), and this means you need to secure it. If you find any chips or cracks in your impeller, you may have to order a new part and replace it.

Vacuum Tube

The vacuum tube is the long tube the air blows out of. If the tube is clogged, you should shut off your leaf blower and disconnect the vacuum tube. Look into it. Do you see a clog? If so, clear out the clog, reattach the tube, and you should be good to go.

However, if the hose is cracked, you may have problems focusing the air to the exiting end of the gas-powered leaf blower. If this is the case, you might be able to fix it temporarily by wrapping duct tape around the hose and pulling it tight. This method should help with airflow, if cracks are a problem.

When To Call For Help

If none of these things work to help you fix your gas-powered leaf blower, you may need to consult a service expert. Your gas-powered leaf blower may need parts replaced, and if you’re not experienced in fixing these lawn care tools, you shouldn’t do it yourself. These experts also have access to a range of parts that may have worn out. Engines can get dirty and sap power from the airflow, and the experts can also clean your engine for you.


Be careful. Repairing a gas-powered leaf blower yourself can be dangerous. You could burn or cut yourself, possibly even lose fingers!

Heavy Use

Keep in mind that through heavy use, the parts on these tools wear out quickly. In fact, they can show signs of wear within the span of only one season. With regular maintenance, you should have few, if any, of the problems described in this article. But if these problems should ever arise, take the necessary steps to keep your tool in good working order.
