You might be worrying why your Craftsman chainsaw is not working after a few uses. There can be several reasons why it won’t start. For instance, the fuel may not be high-quality, or there is a clog in the carburetor.

To help you out, our engineers have laid out some troubleshooting tips to fix a Craftsman chainsaw that won’t start.

Common Solutions to a Craftsman Chainsaw Starting Issues

Here are the most common solutions to fix the starting issues of your Craftsman Chainsaw based on our team’s research and testing:

Fix #1: Ensure You’re Using High-Quality Fuel + Correct Fuel Mix

To ensure that your chainsaw will work adequately, always put fresh and high-quality fuel. Fresh fuel burns perfectly and does not accumulate water in the tank. You also need to add a fuel stabilizer to keep the gas fresh in the tank.

Do not store the fuel inside the tank for longer than three months without a stabilizer. If you are unsure about the correct fuel mix, you can purchase an ethanol-free pre-mixed fuel [1]

Fix #2: Clean the Fuel Filter

Check the next passageway and the fuel filter if you have fresh fuel and the chainsaw still doesn’t start. Similar to a Poulan chainsaw that refuses to run, your chainsaw can be difficult to start if the fuel is not correctly passing through due to a dirty fuel filter. 

You may clean the fuel filter or replace it. You should change a fuel filter at least once a year regardless of how much you use the chainsaw. 

Fix #3: Clean the Air Filter

Like a dirty fuel filter, a dirty air filter can cause problems for your chainsaw. The chainsaw may start then die when given gas, or worse, it may decrease the performance and lifespan of your saw. Check the air filter after using the chainsaw for five hours or refilling your fuel fifteen times.

You can clean the spongy air filter by brushing it. Do not use compressed air to prevent damage. To clean it thoroughly, use warm soapy water and rinse it in cool water. 

Dry it out before putting it back on the chainsaw. You may also replace the filter once a year or as necessary. For compatibility, it’s best to purchase the filter from who made your chainsaw—Craftsman.

Fix #4: Clean the Carburetor

A carburetor combines the fuel and the air to start the engine’s internal combustion. A stock fuel in the engine can become sticky and may clog the carburetor. If the carburetor is clogged, it is hard to start the chainsaw. 

You can do this test to know whether the carburetor is the problem why your Craftsman chainsaw won’t start. Remove the air filter and pour a teaspoon of fuel into it. Try starting the saw. If it starts and dies immediately, the carburetor must be the problem.

Remove the fuel and use a specialized cleaning solution to clean minor clogs. Wipe the carburetor clean. However, if the carburetor is clogged too much, you may need to replace it. Make sure to purchase a compatible carburetor for your chainsaw

Fix #5: Check the Spark Plug for Damages

A spark plug provides a spark needed to ignite a gas-powered chainsaw. If the spark plug is defective, it can’t create a spark to make the chainsaw work. Remove the spark plug from the saw and check for damage or dirt. 

You can also find burned-up electrodes and carbon buildup in the spark plug. You can’t easily clean a spark plug, unlike the previous parts of the chainsaw. Usually, if the spark plug has one or more of the above problems, you need to replace it to safely use the chainsaw. You can also change it annually. 

Fix #6: Replace the Ignition Coil

The ignition coil sends power voltage to the spark plug to work. Repeated use can damage the ignition coil, which can be why your chainsaw doesn’t start. If the spark plug is clean and not damaged, you need to check the ignition coil if you cannot see any spark coming.

You may either buy an ignition coil tester or replace the ignition coil itself. If you have a tester and a spark is not produced during the process, you may need to change the ignition coil.

Fix #7: Check the Rewind Spring for Damages

The rewind spring recoils the starter cord after every pull. The engine won’t start if the cord doesn’t rewind after the first pull or if the rewind spring is broken. You need to change the rewind spring if this happens. 

Check your chainsaw model and see if you can replace the rewind spring individually or if you need to change the whole recoil starter. 


To fix a Craftsman Chainsaw that won’t start, you must identify which part is causing the issue. Our professionals suggest maintaining the cleanliness of each component to prevent further damage. However, you still need to change some parts mentioned above at least once a year, if you use your chainsaw often.
