9 Reasons Why Your Leaf Blower Refuses to Start

Have you ever eagerly anticipated the arrival of autumn, knowing that your trusty leaf blower would make clearing fallen leaves a breeze? But when the time came to fire it up, nothing happened? You’re not alone. Many leaf blowers encounter starting troubles, especially after being dormant for an extended period. The good news is that most issues are easily fixable. In this article, we’ll delve into the nine primary reasons why your leaf blower won’t start and how to overcome them.

1. Stale Fuel

Leaving old fuel in your leaf blower is the number one culprit behind starting problems. Gasoline deteriorates over time, and after just 30 days, it can cause difficulties igniting your machine. Imagine the trouble it can cause if left unused for six months or longer. The fuel may turn into a thick sludge, preventing proper startup. Avoid this predicament by always emptying the fuel before long-term storage. Proactive measures protect you from facing this issue when you need to start your leaf blower again.

2. Carburetor Clogs

A clogged carburetor often stems from the same problem mentioned above. When fuel sits idle for too long, it becomes thick and viscous, leading to carburetor blockages. Examine your carburetor to determine if this is the issue at hand. Depending on the severity, you can either clean the carburetor, rebuild it, or, in the worst-case scenario, replace it entirely. Remember, preventing this problem is as simple as never leaving fuel unused in your blower for extended periods.

3. Fuel Filter Blockage

Another problem related to old, sticky fuel is a blocked fuel filter. Check if your fuel filter is obstructed by gunky fuel. A clogged fuel filter prevents the blower from starting, necessitating a replacement.

4. Oil-Gas Separation

If you possess a leaf blower with a two-stroke engine and have left it unused for some time, the oil and gas in the fuel mix may begin to separate. A quick solution to this issue is to give the tool a good shake before starting it—an easy trick well worth trying. However, if you own a four-cycle leaf blower, this technique won’t help.

5. Faulty Spark Plug

After fuel-related problems, spark plug issues are the next most common cause of starting difficulties. Spark plugs can wear out, become damaged, or get dirty. When this happens, your leaf blower won’t start. If the connection is loose or slightly dirty, fixing it by clipping it back into place or giving it a quick clean should solve the problem. However, if the insulator is cracked, the electrode is burned, or excessive carbon buildup is present, replacement is necessary. It’s good practice to replace spark plugs at the start of every season, especially with frequently used tools.

6. Dirty Air Filter

When the air filter becomes blocked, the fuel and air cannot mix correctly within the engine, leading to blower malfunction. Unlike the previously mentioned issues, this problem occurs due to regular use rather than disuse. To prevent such troubles, regularly clean the air filter. Replace it with a new one if cleaning fails or if it becomes too dirty or clogged.

7. Unprimed Blower

Starting a gas leaf blower requires priming it before pulling the starter cord. Neglecting this step may cause difficulty in starting the blower. Pump the primer around five or six times, then attempt pulling the cord again to check if this is the issue. Always consult the user manual to ensure correct usage and starting procedures.

8. Clogged Spark Arrestor

The spark arrestor is a screen designed to prevent sparks from emitting during operation. A clogged spark arrestor will impede the machine’s functioning. Clean it with a brush to resolve the problem.

9. Broken Rewind Spring

If the rewind spring that powers the starter cord breaks, the cord will fail to rewind after each pull. Replacement of the broken spring becomes necessary.

Why Non-Gas-Powered Leaf Blowers Might Not Start

For battery-powered or corded leaf blowers, starting difficulties are relatively fewer. Begin by checking obvious factors such as power outlet connection, switch position, and battery charge level. If you’ve thoroughly read the manual and followed the correct starting procedure without success, it might be best to seek assistance from a professional repair shop.

Read the Manual and Be Systematic

When faced with starting troubles, ensure that you thoroughly read the manual and understand the correct starting procedure. Then, methodically eliminate potential issues, starting with the simplest and most apparent. This systematic approach allows you to identify and, hopefully, resolve the problem at hand.
