Why does my Echo Blower engine run, but die or not accelerate properly?

  Your Echo Blower might be experiencing issues because of a dirty air filter (clean or replace it), a dirty fuel filter (replace it), or a plugged fuel vent (clean or replace it). Also, check for a dirty or worn spark plug (clean and adjust or replace it), improper adjustment (adjust it), a dirty or plugged cooling system (clean it), or a plugged spark arrestor screen (replace it).

What to do if my Echo PB-251 - 11-09 engine cranks but starts hard or doesn't start?

  Angela DavidAug 6, 2025
  If your Echo Blower engine cranks but struggles to start, the issue might be due to several reasons. There might be no fuel at the carburetor (clean or replace it). If the muffler is wet with fuel, open the choke, clean or replace the air filter, and adjust the carburetor. If there's no spark, turn the switch to the ON position, adjust to .65mm (0.026in.), clean or replace components, and replace the plug.
