10 Possible Reasons Why Chainsaw Won’t Start: Solved

Most professionals use three types of chainsaws. Gasoline is one of them. It has the major problems they face. Here are the 10 possible reasons why chainsaws are not starting.

Chainsaw Won't Start

1 Fuel Check

The first reason is either empty (no fuel) or the fuel is outdated. This is why chainsaws do not start. 


  • Clean the fuel filter first.
  • Refuel the engine with fresh gasoline. 
  • Give it a start.

Fuel tips:

Use 89 graded unleaded gas. This will keep the engine power. Less the grade may damage the engine, or your chainsaw may face piston seizure. 

2 Maybe The Carburetor Is Clogged

Fresh fuel. Still, it is not starting? Time to check the carburetor. Maybe the outdated fuel clogged the carburetor. 

How? Expired fuel gets sticky. As a result, it stuck with carburetors’ air intake area and needle valves. Check out the following solution.


  • Brown or golden carburetor means it needs serious attention.
  • Detach the carburetor first.
  • Use a fresh brush to clean it up. 
  • Wipe the air intake and needle valve.
  • Specialized cleaning sprays are best to clean this area.
  • If there is no option, non-abrasive soap may work.
  • Dry each component and reattach it.
  • Try once again to start the engine.

3: Spark Plug Problems

Is your chainsaw starting now? No! Let’s check the spark plug. Sometimes, this plug shows the following problems: dirty, damaged, or somehow you could not attach it properly. 

These are the common problems. You can solve it. Follow the instructions.


  • Clean the spark plug first.
  • Then start the engine.
  • If it does not start, check the porcelain insulator. 
  • Cracked insulators can stop starting. So, it is better to replace the spark plug.
  • You can check it in the repair shop before changing.
  •  Usually, spark plugs are low-cost. Replacement is a wise choice.

4. Your Engine Might Be Flooded

Spark plug issues are solved. But the engine is not starting. Maybe your engine is flooded, the primer valve issues. 

What is that? The primer valve injects fuel into the engine when you press the start button each time. This valve works two ways: one is, moving the fuel to the engine. 

The second is, to keep the excess fuel in a tank. And this time, most of the problems start. Your engine gets flooded; as a result, the chainsaw stops working.


  • Drain all the excess fuel.
  • Then push the starter while pressing the throttle about 8 times.
  • Reattach the spark plug.
  • Start once again.

5. Air Filter Problem

The problem has to be solved yet, right. Time to check the air filter. The air filter is kind of a nose for the engine. It creates room to breathe and keeps the engine cool.

If the air filter is clogged, the engine will not start. Clogged air filters may cause carburetor damage or even engine damage. So here are the solutions.


  • Remove the air filter
  • Brush it to remove the dirt and grime.
  • Then soak it up in lukewarm soapy water for 2 hours and let it dry.
  • Attach it and start the engine.
  • If it does not start, replace the air filter.

6. Weather Can Be A Big Issue

Low temperature can be the sixth issue. This is unusual for the electric chainsaw. But for gasoline, it’s a major issue. The fuel iced up, and it needs a little more choke to start. So, your living area’s temperature can be a big issue.

7. Ignition Coil Problem

Remember, the topic spark plug problem? This problem can be formed by the ignition coil. The ignition coil sends the voltage to the spark plug. Failing to perform this procedure leads to not starting the engine. 


  • Test your ignition coil with a multimeter tester.
  • If it works, reattach it.
  • Not working! Replace the ignition coil.

8. Recoil Starter Problem

You have done all the possible try. The problem persists. Maybe the recoil spring is the reason. Faulty springs can stop the engine from starting.


  • You have to restructure the total starter assembly.
  • Open the starter assembly.
  • Then remove each component.
  • Take out the recoil starter spring.
  • Replace a new one. Start the engine. Done!


Changing the recoil spring may be tough for a beginner. It is wise to go to the repair shop.

9. Spark Arrestor Problem

A clogged spark arrestor screen can be another problem; it sometimes damages the engine. You will notice that by checking the chainsaw performance. So, where does it situates? Behind the chainsaw. It is inside a hole.


  • Use a screwdriver to untie the arrestor.
  • Take a plier to bring it up from the hole.
  • Burn the arrester with a propane torch. 
  • It will turn the carbon build-up into ashes.
  • Brush up the ashes and reinstall the arrester.

10. Clutch Pad Problem

The clutch pad keeps the chainsaw speed smooth. It’s like a car; you can either slow or speed up. But what if you turn your speed fast, but the chain is running slow? Maybe your clutch pad has the problem.


  • It is wise to go to the repair shop. Your chainsaw needs a new clutch to fix the issue.
