If your Echo Blower engine runs but dies or doesn't accelerate properly, several factors could be responsible. A dirty air filter, fuel filter, or a plugged fuel vent could be the cause; in these cases, clean or replace the respective component. A dirty or worn spark plug might also be the issue, so clean and adjust or replace it. Improper adjustment, a dirty or plugged cooling system, or a plugged spark arrestor screen can also lead to these symptoms. Adjust the settings as needed, clean the cooling system, or replace the spark arrestor screen.
