  If your MTD Tiller engine won't start, several factors could be at play. First, ensure the fuel tank isn't empty; if it is, refill it with fresh fuel. If the tank is full, make sure you've pressed the primer bulb fully and slowly 10 times. If the engine is flooded, squeeze the trigger and pull the starter rope. Old fuel can also be a culprit, so drain the tank and add fresh fuel. Lastly, a fouled spark plug could be the issue; try replacing or cleaning it.
