|Defective spark plug||Clean the carburetor or replace it|
|Bad Switch||Repair or replace the power switch|
|Clog in the fuel filter||Replace the fuel filter|
|Broken starters recoil spring||Replace starters recoil spring|
|Recoil starter||Replace the recoil starter or pulley|
|Defective Ignition Coil||Replace the ignition Coil|
Let’s dig deeper into the reasons!
- Carbon Buildup
Due to carbon buildup and an injured electrode, the sparkplug damages over time, preventing the chainsaw from starting. So if your echo chainsaw doesn’t start, check the spark plug for damage.
Solution: Use an ignition tester to verify if the spark plug is faulty. As a basic guideline, we recommend you replace the spark plug once a year to avoid this trouble.
- Defective Spark Plug
If you leave the residue of old fuel in the tank for a long time, it can build a limitation in the carburetor. Hence you should always fill fresh fuel in the tank.
Solution: Using a fuel stabilizer can help you sustain the quality of the fuel. For better constancy, use a pre-mixed fuel and ethanol-free oil product.
Alternatively, you can clean the carburetor with a carburetor cleaner to remove the clog. If it doesn’t work, buy a carburetor repair kit to replace some parts or install a new one.
- Bad Switch
The ground wire or power switch may get damaged over time and prevent your echo chainsaw from getting the essential power to start.
Solution: Test the switch using a multimeter to verify the issue. Repair or replace the switch if it’s the source of the problem.
- Clog in The Fuel Filter
Another common reason that may prevent your Echo chainsaw from starting is the clog in the fuel filter. Old or bad fuel can also build a clog in the fuel filter and have consequences.
Solution: Replace the filter with a new one.
- Broken Starter Recoil Spring
The rope won’t recoil onto the pulley starter’s recoil spring is damaged. As a result, your echo chainsaw won’t start.
Solution: Replacement is a better solution here. Though you can only replace the recoil springs, replacing the whole recoil starter will be much easier.
- Recoil Starter
The recoil starter can be unable to connect with the saw engine’s crankshaft. Hence, your echo chainsaw may refuse to start.
Despite this, the recoil starter pulley pulls back the starter rope when it’s not in use. If the recoil pulley is wrecked or stuck, it won’t pull back the rope, resulting in the chainsaw engine won’t start.
Solution: Replace the broken pulley or the starter assembly to solve the problem.
- Ignition Coil
The ignition coil transfers voltage to the spark plug while running the engine. If this part is defective, your echo chainsaw won’t start. Make sure the spark plug is working well before replacing the ignition coil.
After finding the spark plug in working condition, check the coil using an ignition coil tester.
Solution: Replace the coil if you find it defective.
Video on Why Echo Chainsaw Won’t Start
Apart from the above reasons, watch the video for better troubleshooting:
- Why won’t the new echo chainsaw start?
If your brand new chainsaw won’t start, empty the stale gas from the tank and fill it with fresh mixed gas. Regular gas that is older than one month is known as stale. Apart from no start, stale gas also causes poor running, stalling, lack of power, or bogging down.
- Why do echo chainsaws get fuel but not start?
A clogged carburetor can be the source of this hassle. The carburetor of a chainsaw can clog if the user leaves fuel in the engine for a long time. However, cleaning out the carburetor will help restore its performance.
- Why does the Echo chainsaw start and then stop?
Your Echo chainsaw may also start and stop due to a clogged carburetor. After a long time, the ingredients in the fuel may leave a thicker and stickier core inside the carburetor and clog it up. Hence, the engine may try to start up and stop down.
In short, lack of maintenance is the core reason why the echo chainsaw won’t start. While regular maintenance can let your echo chainsaw perform optimally, repairing at the initial stage can also bring the penalty down.
Replacing the faulty parts is the last resort, and you must find a compatible replacement to fix your echo chainsaw successfully.
