How to fix MTD Lawn Mower engine that fails to start?
- A
  Amanda MillerAug 6, 2025
  Several factors can cause the MTD Lawn Mower engine to fail to start. Here are a few things to check: * Ensure the blade control handle is engaged. * Verify the spark plug wire is connected to the spark plug. * Make sure the fuel tank is filled with clean, fresh gasoline. Other potential issues include a faulty spark plug (clean, adjust gap, or replace), a blocked fuel line (clean it), or engine flooding (wait a few minutes to restart, without priming). Also, check if the fuel valve is open (if equipped) and that the engine is properly choked (if equipped with a choke). For electric start models, a burnt fuse could also be the culprit (replace the fuse, referring to the Maintenance Section).

Why does my MTD YARD-MAN 12AV569Q501 Lawn Mower engine run erratic?
- C
  Christopher RoachAug 10, 2025
  If your MTD Lawn Mower engine runs erratically, start by checking the spark plug wire to ensure it's securely connected and tightened. Also, verify that the fuel line isn't blocked and that you're using clean, fresh gasoline. A plugged gas cap vent could also be the issue, so clear the vent. Additionally, water or dirt in the fuel system can cause problems; drain the fuel tank and carburetor and refill with fresh fuel.

Why MTD YARD-MAN 12AV569Q501 Lawn Mower will not mulch grass?
- L
  Lonnie WilliamsAug 14, 2025
  If your MTD Lawn Mower is not mulching grass effectively, it could be due to several reasons. Avoid mowing when the grass is wet; wait until it's drier. If the grass is excessively high, mow once at a higher cutting height, then mow again at the desired height, or try making a narrower cutting path. A dull blade can also hinder mulching, so sharpen or replace it.
