Why does my Echo PB-251 Blower engine crank but not start?
- J
  Jerry WilsonJul 26, 2025
  If your Echo Blower engine cranks but struggles or fails to start, there could be several reasons: * The fuel strainer or fuel line might be clogged, requiring cleaning or replacement. * The fuel mixture may be too rich, in which case you should open the choke. * There might be no spark at the end of the plug wire. Turn the switch to the ON position. * The spark plug may be defective, covered with carbon, or fouled with fuel, requiring cleaning, replacement, or adjustment to .65mm (0.026in.). For carburetor, electrical, or interlock switch issues, consult your Echo dealer.

  If your Echo Blower starts but either dies or doesn't accelerate correctly, consider these possibilities: * Contaminants or residues may be present in the fuel, necessitating fuel replacement or cleaning/replacement of fuel-related components. * The carburetor may have issues due to normal wear and tear, requiring cleaning, adjustment, or replacement. * The cooling system might be dirty or plugged, requiring cleaning. * There may be improper carburetor adjustment, which requires proper adjustment.

  If the engine of your Echo Blower runs, but the blower itself is weak or uneven, check for these issues: * There may be a build-up of debris, so unclog the blower. * Vibration could be the cause, so tighten any loose components. * Wear or misuse may have damaged parts, requiring replacement.
