Why Troy-Bilt Lawn Mower engine fails to start?
- AAlyssa MorrisAug 13, 2025
If your Troy-Bilt Lawn Mower engine fails to start, there are several possible causes. Ensure the PTO/Blade is disengaged by placing the knob (or lever) in the OFF position and the parking brake is engaged. Check that the spark plug wire is connected to the spark plug. The fuel tank may be empty or contain stale fuel, so fill it with clean, fresh gas (less than 30 days old). Make sure the choke is activated by placing the throttle control in the CHOKE position. The spark plug may be faulty, so clean, adjust the gap, or replace it. A blocked fuel line can also prevent starting, so clean the fuel line and replace the fuel filter. If the engine is flooded, crank it with the throttle in the FAST position. Also, ensure the throttle control lever is in the FAST position.
