  The Troy-Bilt Lawn Mower engine may fail to start due to several reasons. First, ensure the PTO lever is disengaged (OFF). Next, engage the parking brake. Check that the spark plug wire(s) are connected to the spark plug. Make sure the throttle control lever is in the FAST position. If these steps don't work, pull out the CHOKE control and fill the tank with clean, fresh gas (less than 30 days old). Other potential causes include a blocked fuel line (clean or replace the fuel filter), a faulty spark plug (clean, adjust gap, or replace), or a flooded engine (crank the engine with the throttle in the FAST position).

  If your Troy-Bilt Lawn Mower engine runs erratically, it could be due to several reasons. First, ensure the CHOKE control is pushed in. Check and tighten the spark plug wire. If the issue persists, the fuel line may be blocked, or the fuel may be stale; clean the fuel line and fill the tank with fresh gasoline. Another cause could be a plugged vent in the gas cap; clear the vent or replace the cap if damaged. Water or dirt in the fuel system can also cause this issue; drain the fuel tank. Lastly, a dirty air cleaner can cause erratic engine performance; replace the air cleaner cartridge/element or clean the pre-cleaner, if equipped.
