If your Troy-Bilt Lawn Mower engine runs erratically, consider these potential causes and solutions: - The tractor is running with the CHOKE activated. Move the throttle/choke control lever into the choke off position. - Spark plug wires are loose. Connect the spark plug wires. - The fuel line is blocked or the fuel is stale. Clean the fuel line, fill the tank with clean, fresh gasoline, and replace the fuel filter. - The vent in the gas cap is plugged. Clear the vent or replace the cap if damaged. - There is water or dirt in the fuel system. Drain the fuel tank and refill with clean, fresh gasoline. - The air cleaner is dirty. Replace the air cleaner paper element or clean the foam precleaner.
