  If your Troy-Bilt Lawn Mower engine runs erratically, it could be due to: running with the CHOKE activated (pull the throttle control lever rearward from the choke position), loose spark plug wire(s) (connect them), a blocked fuel line or stale fuel (clean the fuel line, fill the tank with clean, fresh gasoline, and replace the fuel filter), a plugged vent in the gas cap (clear the vent or replace the cap if damaged), water or dirt in the fuel system (drain the fuel tank and refill with clean, fresh gasoline), or a dirty air cleaner (replace the air cleaner paper element or clean the foam precleaner).
