What to do if Craftsman 247.203753 engine runs erratically?
- CcarlascottAug 21, 2025
If your Craftsman Lawn Mower engine is running erratically, it could be due to: * Running with the CHOKE activated: Deactivate the CHOKE. * Loose spark plug wire(s): Connect the spark plug wire(s). * Blocked fuel line or stale fuel: Replace the fuel line, fill the tank with clean, fresh gasoline, and replace the fuel filter. * Plugged vent in the gas cap: Clear the vent or replace the cap if it's damaged. * Water or dirt in the fuel system: Drain the fuel tank and refill it with clean, fresh gasoline. * Dirty air cleaner: Replace the air cleaner paper element or clean the foam pre-cleaner, if equipped.
