Frequently Asked Questions
What is the purpose of the ignition coil in a Craftsman leaf blower?
The ignition coil is a crucial component in a Craftsman leaf blower, responsible for generating the high voltage needed to create a spark in the engine. This spark is essential for igniting the fuel and air mixture, which powers the engine.
What are the signs that the ignition coil needs to be replaced?
Common signs that the ignition coil needs to be replaced include a weak or intermittent spark, engine misfires, difficulty starting the engine, or a complete failure to start. If you notice any of these symptoms, it's likely that the ignition coil is faulty and needs to be replaced.
Can I replace the ignition coil myself, or do I need a professional?
Replacing the ignition coil is a relatively straightforward process that can be done by a DIY enthusiast with basic mechanical skills. However, if you're not comfortable with DIY repairs or don't have experience working with small engines, it's recommended to seek the help of a professional.
What tools do I need to replace the ignition coil?
To replace the ignition coil, you'll need a few basic tools, including a socket wrench, spark plug socket, and a new ignition coil. It's also a good idea to have a repair manual specific to your Craftsman leaf blower model for reference.
How do I access the ignition coil on my Craftsman leaf blower?
The ignition coil is typically located near the spark plug and is held in place by a few screws or clips. You may need to remove some plastic covers or shrouds to access the coil. Consult your repair manual for specific instructions on how to access the coil on your particular model.
What type of ignition coil do I need for my Craftsman leaf blower?
Make sure to purchase an ignition coil that is compatible with your Craftsman leaf blower model. You can find this information in your repair manual or on the manufacturer's website. Using the wrong type of coil can lead to poor performance or even damage to your engine.
How do I test the ignition coil to see if it's working properly?
To test the ignition coil, you'll need a spark tester. Attach the tester to the spark plug wire and crank the engine. If you see a strong, blue spark, the coil is working properly. If the spark is weak or nonexistent, the coil is likely faulty.
Can I clean the ignition coil instead of replacing it?
In some cases, a dirty or corroded ignition coil can be cleaned and restored to working condition. However, if the coil is damaged or worn out, cleaning it won't make a difference. It's usually more cost-effective and reliable to replace the coil altogether.
How long does it take to replace the ignition coil?
The replacement process typically takes around 30 minutes to an hour, depending on your level of mechanical expertise and the complexity of the job. If you're new to DIY repairs, it may take longer.
What are some common mistakes to avoid when replacing the ignition coil?
