What to do if my DR Lawn Mower engine won’t start?
- JJason SmithJul 26, 2025
To troubleshoot a DR Lawn Mower engine that won’t start: * Ensure the spark plug wire is connected. * Verify the key is in the START position. * Use fresh, clean gas, and add a fuel stabilizer if storing gas for over a month. * Check the Fuel Filter to ensure it is clear; remove the fuel line from the engine side of the filter to check for free flow. * Check the Throttle adjustment and travel. * Confirm the Blade Engagement Control Lever is down and the Shift Lever is in NEUTRAL. * Inspect the spark plug; replace if dirty or cracked. * If the spark plug is oily, remove it, cover the spark plug hole with a rag, pull the recoil cord several times to clear oil from the cylinder, and then clean and reinsert the spark plug.
