  • Ensure you have enough fuel in the tank.
  • Check that the choke is in the correct position.
  • Verify that the air filter is clean and free of debris.

Step 2: Investigate Fuel-Related Issues

If the basics check out, it’s time to investigate fuel-related issues:

  • Check the fuel mix ratio and adjust as needed.
  • Try running the leaf blower with fresh fuel to see if that resolves the issue.
  • Inspect the fuel filter and clean or replace it as needed.

Step 3: Examine Air Filter and Spark Plug

Next, examine the air filter and spark plug:

  • Remove and clean the air filter, or replace it if it’s damaged.
  • Check the spark plug for signs of wear or fouling, and replace it if necessary.

Step 4: Inspect Belts, Muffler, and Electrical Components

If the above steps don’t reveal the issue, it’s time to inspect other components:

  • Check the belts for wear or looseness, and adjust or replace as needed.
  • Inspect the muffler for blockages, and clean it out if necessary.
  • Check electrical components, such as wires and switches, for signs of wear or damage.

Conclusion

A leaf blower that runs then shuts off can be frustrating, but it’s often a sign of a simple issue that can be easily resolved. By following the troubleshooting steps outlined above, you should be able to identify and fix the problem, getting your leaf blower up and running in no time. Remember to stay on top of regular maintenance to prevent these issues from arising in the first place. Happy blowing!
