New Echo CS 400 Won’t Start
When the chainsaw is brand new, it is obvious that its parts are clean and there is no clogging of any kind. And yet your chainsaw is not starting. Why is that?
Air-Locked Fuel System
A common problem with new saws since they do not have fuel in the system is that the fuel lines are filled with air. Chainsaw uses a diaphragm gasket to move gas from the tank to the carburetor. Pulling the cord a few times can push the gas and force the air out.

This can be tested by examining the spark plug. If it is dry then the system is air-locked. Fix this by removing the air filter and dropping a bottle cap full of fuel mix into the carburetor intake. Now the chainsaw will start at the second or third pull. If not, repeat the procedure.
Fuel Requirement
Make sure the oil-to-gas ratio you are using is correct. Echo CS-400 2-stroke engine requires a 50:1 ratio of gas and oil. Consult the manual for further details.
Too much oil makes the mix too strong and that can damage the spark plug. A damaged plug can misfire and flood the engine. If this is the problem then drain the fuel tank, refill it with the right mix and clean the spark plug.
Echo Chainsaw Starting Procedure
It is a dangerous situation if the throttle is stuck wide open or depending on where the piston is the saw can jerk downwards. The approved way is to put it on the ground or flat surface with no obstacle around it before starting it.
Whether it’s a cold or a warm start make sure you have your safety measures on. These include:
- Wearing your work gloves.
