Chainsaw Won’t Start – Troubleshooting Guide | 2023


Having trouble starting your chainsaw? Don’t worry, we’ve got you covered. In this article, we will provide you with a troubleshooting guide to help you identify and fix the most common issues that may prevent your chainsaw from starting. Whether you’re a professional arborist or a homeowner, these tips will come in handy when you find yourself in a frustrating situation with a non-starting chainsaw.


Q: Why won’t my chainsaw start?

A: There could be several reasons why your chainsaw won’t start. It could be due to a fuel-related problem, ignition issues, or even a clogged air filter. The troubleshooting guide below will help you diagnose and fix the problem.

Q: What should I do first?

A: The first step is to check the fuel tank. Ensure that it is filled with fresh gasoline mixed with the correct oil-to-gas ratio. If the fuel is old or contaminated, it can prevent the chainsaw from starting.

Q: How do I check for ignition issues?

A: Start by removing the spark plug and inspecting it for any signs of damage. If the spark plug is dirty, clean it with a wire brush. If it is damaged or worn out, replace it with a new one. Additionally, check the ignition switch and wiring for any loose connections or damage.

Q: What if the chainsaw still doesn’t start?

A: If the chainsaw doesn’t start after checking the fuel and ignition, the next step is to inspect the air filter. A clogged or dirty air filter can restrict airflow and prevent the engine from starting. Clean or replace the air filter if necessary.

Q: Are there any other common issues to consider?

A: Yes, there are a few more things to check. Make sure the chainsaw’s chain brake is disengaged, as it can prevent the engine from turning over. Check the fuel lines for any cracks or leaks, and ensure that the carburetor is clean and functioning properly.

Q: Can I fix the chainsaw myself?

A: In many cases, you can fix the chainsaw yourself by following the troubleshooting steps mentioned above. However, if you’re unsure or uncomfortable with performing the repairs, it’s always best to seek professional help.

Q: How can I prevent future starting issues?

A: Regular maintenance is key to preventing starting issues. Keep your chainsaw clean, properly lubricated, and store it in a dry place. Use fresh fuel and replace the spark plug and air filter regularly. Following these maintenance practices will help ensure that your chainsaw starts reliably when you need it.

Q: When should I consult a professional?

A: If you’ve exhausted all troubleshooting steps and your chainsaw still won’t start, it’s time to consult a professional. They have the expertise and specialized tools to diagnose and fix complex issues that may be preventing your chainsaw from starting.


A chainsaw that won’t start can be frustrating, but with the help of this troubleshooting guide, you’ll be able to identify and resolve the most common issues. Remember to follow proper safety precautions when working with chainsaws, and if in doubt, seek professional assistance. Keeping your chainsaw well-maintained will ensure that it starts reliably and serves you for years to come.
