  If your Troy-Bilt Lawn Mower engine runs erratically, consider these potential causes and solutions: * The tractor might be running with the CHOKE activated. Move the Throttle/Choke control out of the CHOKE position. * Spark plug wires may be loose. Connect the spark plug wires securely. * The fuel line may be blocked, or the fuel may be stale. Clean the fuel line, fill the tank with clean, fresh gasoline, and replace the fuel filter. * The vent in the gas cap may be plugged. Clear the vent or replace the cap if it's damaged. * There might be water or dirt in the fuel system. Drain the fuel tank and refill it with clean, fresh gasoline. * The air cleaner may be dirty. Replace the air cleaner paper element or clean the foam precleaner.

Why Troy-Bilt Lawn Mower is not mulching grass?
- K
  Kristine JohnsonAug 20, 2025
  Your Troy-Bilt lawn mower might not be mulching grass effectively due to: * Engine speed being too low. Place the throttle in the FAST (rabbit) position. * Wet grass. Avoid mulching when the grass is wet. * Excessively high grass. Mow once at a high cutting height, then mow again at the desired height, or make a narrower cutting swath. * Dull blade. Sharpen or replace the blade.

  If your Troy-Bilt Lawn Mower engine idles roughly, it could be due to: * Spark plugs that are fouled, faulty, or have a gap that is too wide. Replace the spark plugs and set the plug gap. * A dirty air cleaner. Replace the air cleaner element and/or clean the pre-cleaner.
