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.
Ethanol-blend fuel varnish in the float bowl during winter storage causes most 11A-020W765 hard-start complaints. Cleaning restores function in most cases. When the needle valve seat is worn or the float bowl gasket has hardened, carburetor replacement is the most reliable solution.
Annual spark plug replacement maintains reliable starting and clean combustion. A plug with black carbon deposits indicates a rich mixture from a clogged air filter or gummed carburetor.
Replace the air filter at the start of each mowing season. A mower operating in tall grass accumulates air filter debris faster than equipment operating in cleaner environments.

Hard starting after storage is almost always caused by carburetor varnish from ethanol-blend fuel in the float bowl during warm months. Drain the carburetor float bowl before winter storage to prevent this at zero parts cost.
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, or a deck that has lost proper leveling. Replace a bent blade immediately rather than attempting to straighten it.
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.
