  If your Toro Lawn Mower engine won't start, starts with difficulty, or doesn't stay running, begin by checking if the fuel tank is empty and fill it with fuel if needed. Inspect the air cleaner for dirt and clean or replace the air cleaner element. Ensure the spark plug wire is securely connected to the spark plug. Replace any spark plugs that are pitted, fouled, or have an incorrect gap with new, correctly gapped spark plugs.

  If your Toro Lawn Mower engine is losing power, start by reducing the ground speed to lessen the engine load. Check and clean the air cleaner element. Ensure the oil level in the crankcase is adequate; add oil if it's low. Clear any obstructions from the cooling fins and air passages above the engine. Replace any spark plugs that are pitted, fouled, or have an incorrect gap with new, correctly gapped spark plugs. For issues like a cracked muffler, broken Oxygen sensor, dirt in the fuel filter, or contaminated fuel, it's best to contact an Authorized Service Dealer.
