  If your MTD Lawn Mower engine won't start, several factors could be the cause. First, ensure that the blade control handle is engaged. Check that the spark plug wire is securely connected. Make sure the fuel tank isn't empty or filled with stale fuel; if so, fill it with fresh gasoline. A blocked fuel line could also be the culprit, so try cleaning it. Inspect the spark plug for faults and clean, adjust the gap, or replace it if necessary. Lastly, if the engine is flooded, wait a few minutes before attempting to restart it, and avoid priming.
