Check the fuel
- Make sure the tank is not empty
- Use fresh fuel (old fuel can clog the system and cause stalling)
Fix:
Refill with fresh fuel. If fuel is old, drain and replace it.
Check the choke position
- Cold start: use FULL choke
- After starting: switch to RUN
If the choke stays on FULL, the engine may stall after starting.
Check the air filter
A dirty air filter blocks airflow and can cause the engine to stop.
Fix:
- Remove the air filter
- Clean or replace it if dirty or damaged
Check the spark arrestor
The spark arrestor can become clogged with carbon, restricting airflow.
Fix:
- Remove and clean it with a wire brush
- Replace if heavily clogged
Check fuel flow issues
If the leaf blower dies when tilted or during use:
- The fuel filter may not be reaching fuel properly
- Fuel lines may be blocked or damaged
Fix:
Inspect and replace if needed.
