Why does my Echo PB-770 H/T engine crank but not start?
- BBrooke LynchJul 26, 2025
If your Echo Blower's engine cranks but struggles to start or doesn't start at all, several factors could be at play. The fuel strainer or fuel line might be clogged, requiring cleaning or replacement. A fuel mixture that's too rich could also be the culprit; in this case, try opening the choke, cleaning or replacing the air filter, or adjusting the carburetor. Other potential issues include a lack of spark, which may require turning the switch to the 'ON' position. Also check the spark plug: the gap might be incorrect (adjust to .65mm), it could be covered with carbon or fouled with fuel (clean or replace), or the plug itself might be defective (replace it). For carburetor or no spark issues, consult your Echo dealer.
