Why won't my Toro GrandStand 74534TE engine start?

If your Toro Lawn Mower engine won't start, starts hard, or fails to keep running, several factors could be the cause. First, ensure the fuel tank isn't empty and the shut-off valve is open; if not, fill the tank and open the valve. Also, make sure the choke is on by moving the choke lever to the choke position. Check that the spark plug wire is securely connected to the spark plug. Inspect the spark plug itself; if it's pitted, fouled, or the gap is incorrect, replace it with a new, correctly gapped one. A dirty air cleaner can also cause this issue, so service the air cleaner element. Finally, check the fuel filter for dirt and replace it if necessary.
