Most Replaced Parts on the MTD 12AVB2RQ719
Cutting Blade for the MTD 12AVB2RQ719
A blade bent from striking a rock or debris must be replaced immediately rather than straightened. Replace the blade when it can no longer be sharpened to a clean cutting edge.
Carburetor for the 12AVB2RQ719
Ethanol varnish deposits during off-season storage cause most hard-start complaints. Cleaning restores function in most cases. When the needle valve seat is worn, carburetor replacement is the most reliable solution.
Spark Plug for the MTD 12AVB2RQ719
Annual spark plug replacement maintains reliable starting. A plug with black carbon deposits indicates a rich mixture from a clogged air filter or gummed carburetor.
Air Filter for the 12AVB2RQ719
Replace the air filter at the start of each mowing season. A mower operating in tall or dusty conditions accumulates filter debris faster than equipment operating above ground.

MTD 12AVB2RQ719 Lawn Mower Parts FAQ
What is the MTD 12AVB2RQ719 and what platform does it use?
The MTD 12AVB2RQ719 is a walk-behind gas lawn mower from MTD Products. The 12A series identifies the MTD walk-behind mower product line, and B2RQ719 identifies the specific deck size, engine, and configuration within that series.
Why does my MTD 12AVB2RQ719 not start after off-season storage?
Hard starting after storage is almost always caused by carburetor varnish from ethanol-blend fuel sitting in the float bowl during warm months. Drain the float bowl before off-season storage to prevent this. Clean the carburetor before ordering a replacement.
Why does my MTD 12AVB2RQ719 cut unevenly?
Uneven cutting is most commonly caused by a blade bent from striking a rock or debris, a blade that has become dull enough to tear rather than cut grass, or a deck that has lost proper leveling. Replace a bent blade immediately rather than attempting to straighten it.
How do I safely remove the blade on the MTD 12AVB2RQ719?
Disconnect the spark plug wire before working under the deck. Tip the mower on its side with the air filter and carburetor facing up to prevent oil spillage. Block the blade from turning with a wooden block, then remove the blade bolt counterclockwise.
