Leaf blowers blow leaves off the lawn and make living with trees more manageable. The two different kinds of leaf blowers, electric and gas, have both similar and individual problems, but one commonality between the types is that they are both built so that the consumer can repair them at home. This saves both time and money as a repairman can cost upward of $100 for any repair, even for changing a spark plug.
Check to see if the power cord is plugged in if your leaf blower is an electric version. Make sure the cord is not any longer than 75 feet as electric leaf blowers lose massive amounts of power over that length. The engine may seem faulty if any of these problems occur.
Replace the fuel in a gas leaf blower if it has been sitting in the blower for more than a month. Old gas begins to corrode and does not function properly, causing the motors to be less powerful. New fuel will revitalize the motor.
Feel the gas tank for any leaks. There will be a strong odor of gas if a leak exists. Use a plastic sealant to fill the leaks.
Inspect the spark plug. It will be located on the top of the motor under a black house. Look for any cracks, especially on the tip. If the tip is broken off or there are any cracks, replace the spark plug with a new one.
