Why my Echo PB-255 engine cranks but starts hard or doesn't start?

  If your Echo Blower engine cranks but has trouble starting or doesn't start at all, several factors could be responsible. It might be due to no fuel reaching the carburetor, in which case you should clean or replace it. A muffler wet with fuel could also be the cause; open the choke, clean or replace the air filter, and adjust the carburetor. If the spark plug gap is incorrect, covered with carbon, fouled with fuel, or defective, adjust the gap to .65mm (0.026in.), clean or replace the plug, or replace the plug entirely. Ensure the switch is in the ON position.

What to do if my Echo PB-255 engine runs, but dies or does not accelerate properly?

  If your Echo Blower engine runs but dies or doesn't accelerate properly, there are several potential causes. A dirty air filter, fuel filter, or a plugged fuel vent can be the issue; in such cases, clean or replace the air filter, replace the fuel filter, or clean/replace the fuel vent. A dirty or worn spark plug may also be the reason; clean and adjust or replace it. Improper carburetor adjustment could be another cause, so adjust it accordingly. Additionally, check if the cooling system is dirty or plugged and clean it. Finally, a plugged spark arrestor screen could be the culprit; replace it to resolve the issue.

  If the engine of your Echo Blower runs, but the blower itself isn't working, or the airflow is weak or uneven, check the pipe for clogs and unclog it. Also, ensure the pipe is tightened. If the pipe is damaged, it should be replaced.
