  If your Cub Cadet Lawn tractor engine runs erratically, first ensure the choke is not activated. Check and tighten the spark plug wires. Clean the fuel line, use fresh gasoline, and replace the fuel filter if needed. Clear the vent in the gas cap or replace it if damaged. Drain the fuel tank and refill with fresh gasoline if there's water or dirt in the system. Finally, replace the air cleaner paper element or clean the foam precleaner if the air cleaner is dirty.
