Echo Chainsaw Won’t Start: Possible Problems with Solutions
With lightweight, fancy features, power, and reliability, echo chainsaws are popular among professional woodworkers and DIY’ers. So if your new Echo CS 310 chainsaw won’t start, don’t delay troubleshooting.
The following are the most common reasons for preventing the echo chainsaw from starting, along with quick solutions:
|Carbon buildup||Replace the spark plug|
|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 spark plug gets damaged 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.
