Recoil Starter

The rewind spring, the recoil starter pulley, and the magneto assembly consist of electromagnet windings and a magnet, are 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 greatest precious parts of the chainsaw to make it start is the ignition coil. If it's broken or damaged somehow, even your new chainsaw won’t start. It converts the low voltage into 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

Excessive pushing of the fuel pump or 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 to a flooded engine and it’s time for some fuel draining.

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 to the piston rings leakage. If either of the issues occurs, it's time for changing the compression rings. Otherwise, they won't be able to produce enough heat for sparking.

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 a 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

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

Clogged Carburetor

A clogged carburetor can cause your chainsaw not getting 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 setting on 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.

  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.
