This occurrence might happen to anyone, whether it’s an old or new chainsaw for private or regular use. We’re here with some of the primary causes behind a chainsaw’s starting issues and some tips to get over those problems. It’s always better to know the reasons so that you can overcome the issues you’re having. Shall we begin?

Why Doesn’t Your Chainsaw Start Even if It has Spark and Fuel?

Check out the technical errors and damages why your chainsaw has sparked but won’t start. Know the issues and eliminate them from their roots.

Chainsaw won't start

Recoil Starter

The rewind spring, the recoil starter pulley, and the magneto assembly consist of electromagnet windings, and a magnet is the three main parts of the recoil starter. If either of these parts is broken or worn out somehow, your chainsaw won’t start, so the chainsaw needs maintenance. Check them and replace them as required.

The Ignition Coil

One of the most significant precious parts of the chainsaw to make it start is the ignition coil. If it’s broken or damaged somehow, even your brand-new chainsaw won’t start with starting fluid. It converts the low voltage into a high voltage to perform the electric spark. Use an ignition coil tester or a multimeter and check if there’s an error. If so, replacing the coil is the only solution.

A Flooded Engine

If your chainsaw has spark and fuel but won’t start, it may cause excessive pushing of the fuel pump, or the primer bulb can cause a flooded engine. When you can smell the fuel while starting the saw or feel too much moisture around the spark plug, that indicates a flooded engine. So, because of flooding with fuel, the chainsaw is not starting. Now it’s time for some fuel draining.

Following an aggressive chainsaw chain can draw the highest performance, have a try.

Compression Rings

Check the compression rings. If they’re exhausting bluish gases, it means they are worn out, or you can also check the spark plug how often it gets sooty deposits. That indicates the piston ring leakage. If either of the issues occurs, it’s time to change the compression rings. Otherwise, they won’t be able to produce enough heat for sparking, and your chainsaw starting problem will not be solved.

Fuel Filters

It’s normal that after using a limited amount of time, the fuel filter of your chainsaw will get clogged. It traps dirt because of the oil. Such clogging blocks the fuel to pass in the required amount. So, keep changing and cleaning the fuel filter regularly after using it several times.

Dirty Air Filters

Dirty and clogged air filters also prevent the saw from getting a start. Remove and clean the air filter after 5 hours of usage.

Clutch Pads

Because of the broken clutch pads, the gear assembly doesn’t get enough power transferred from the crankshaft’s flywheel. Because cracked clutch pads can’t attach that flywheel properly, it prevents starting the saw. To avoid this, you have to replace the whole set of the clutch plate.

Clogged Carburetor

A clogged carburetor can cause your chainsaw not to get started. Fuel evaporation is the main reason for such clogging. You have to clean the fuel tank and also the carburetor regularly to prevent unwanted clogging.

Spark Arrestor

The spark arrestor prevents fire in the dry season because of the exhausting particles from a spark. But it gets clogged with time and causes unintentional blocking to burn the fresh fuel-air mixture well. So, to avoid this situation, it requires replacement after every 24 hours of usage.

How to Maintain a Chainsaw for having Continuous Easy Starts?

Well, in the above section, you’ve got to know the issue while staring at a chainsaw and its remedies. Now, let us help you with some tricky tips for maintaining and getting your chainsaw started at any time, regardless of its age.

  • Never use it for over forty hours without service. You should maintain servicing the chainsaw every time after using it for 25 hours. 
  • Try to use or at least run your chainsaw regularly just to keep all its parts active.
  • The more you use a chainsaw, the quality of the fuel gets worse with time. For a fast and easy start to the chainsaw, try to use fresh fuel.
  • If you ever notice or doubt that one or some of the parts are not working properly, check it soon and replace it as soon as possible without wasting a single moment.
  • Whenever you’re replacing or changing any part of your chainsaw, make sure it’s an original spare part. Otherwise, it will wear out sooner and also make other parts weak and disabled.
  • Avoid dump places to store the chainsaw. Make sure it’s a dry and clean place where you’re storing it to avoid damage.

  1. Sorry. But the main issue with hard to start or no starting is fuel. Gasoline starts to go bad immediately when you purchase. The ethanol that is added to fuel attracts water. Take a small amount of fuel and pour some into a metal container. Let it sit for a day. The fuel will start to get milky. Today’s small engine manufactures warn you if you use E85 fuel or any fuel with more than 10 percent ethanol you just voided the warranty. I’ve been servicing lawn and equipment for over 40 years. And this is the reason most equipment comes in for service. Purchase ethanol free gas and this will solve most starting issues you’ll have.
