  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 spark plug can cause these issues; try cleaning or replacing them. A plugged fuel vent or spark arrestor screen may also be the culprit; clean or replace them as needed. Improper carburetor adjustment or a dirty/plugged cooling system could also be the cause, so adjust the carburetor or clean the cooling system.

  If your Echo Blower engine cranks but struggles to start or doesn't start at all, there could be several reasons. It might be due to a lack of fuel at the carburetor, in which case you should clean or replace it. If the muffler is wet with fuel, open the choke, clean or replace the air filter, and adjust the carburetor. Also, ensure the switch is turned ON. If there's no spark, adjust it to 0.65mm (0.026 in.), and clean, or replace the spark plug.

  If your Echo Blower runs, but the blower doesn't work or is weak or uneven, it could be due to a clogged, loose, or damaged pipe. Try unclogging or tightening the pipe. If damaged, replace it.
