What to do if Cub Cadet Lawn Mower engine runs erratic?
- BBrandon CarterAug 16, 2025
If your Cub Cadet Lawn Mower engine is running erratically, consider these potential causes: * The tractor may be running with the Throttle/Choke activated. Push the Throttle/Choke control in. * Spark plug wires could be loose. Connect and tighten them. * The fuel line may be blocked, or the fuel could be stale. Clean the fuel line, fill the tank with clean, fresh gasoline, and replace the fuel filter. * The vent in the gas cap might be plugged. Clear the vent or replace the cap if it's damaged. * There could 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.
