Craftsman 917388110 lawn mower Parts

The most common issues we see with the Craftsman 917388110 walk-behind mower are starting problems, uneven cutting, poor bagging or side discharge, and self-propel or control-cable issues. Most fixes come down to basic maintenance, correct cutting height setup, and replacing worn wear-parts.

Common problems and what usually causes them

• Won’t start or starts then dies: old fuel, dirty air filter, fouled spark plug, or carburetor varnish
• Cuts unevenly or scalps: bent/dull blade, wrong height setting, wheel height hardware worn or mis-set
• Clumps grass or leaves rows: mowing too fast, wet/tall grass, deck packed with debris, blade worn
• Poor side discharge: discharge door not closing/opening correctly, spring fatigue, chute obstruction
• Poor bagging: bag full or clogged, rear door not sealing, airflow restricted under the deck
• Operator presence/control issues: stretched or misrouted control cable, loose clamps or handle hardware

Quick checks we recommend first (fast, high-impact)

• Drain old fuel and refill with fresh fuel; set choke/throttle per the 917388110 owner’s manual.
• Inspect and clean under the deck (disconnect the spark plug wire first).
• Check blade condition; replace if bent, cracked, or badly worn.
• Verify all four wheels are set to the same cutting height.
• Confirm the discharge door and springs move freely and return fully.

Parts that commonly solve these symptoms

If you find damage or excessive wear, these model-matched parts are frequent fixes:

Symptom	Part to inspect	Example part on this model
Uneven cut, vibration, poor cut quality	Blade and blade mounting	Lawn mower blade 532406712, blade adapter 532418373
Discharge door not returning	Door springs	Lawn mower discharge chute door spring, left 532405421, lawn mower discharge chute door spring, right 532405423
Safety/control feel is wrong	Control cable routing/tension	Lawn mower zone control cable 532183281
Bagging issues	Bag and rear door sealing	Lawn mower grass bag 532410666, rear door assembly 532401814

Why it matters

A sharp, properly mounted blade and correct deck airflow are what make a mower cut cleanly and bag or discharge well. When the blade, adapter, door springs, or control cable wear out, performance drops quickly and the mower can become harder to operate.

For the Craftsman 917388110 gas walk-behind mower, use fresh regular unleaded gasoline (most commonly E10). Avoid premium/high-octane fuel unless your engine label or manual specifically calls for it; it typically provides no benefit in small 4-cycle mower engines.

What to use (and what to avoid)

• Use fresh regular unleaded gasoline from a busy station.
• E10 (up to 10% ethanol) is the most common and works for most walk-behind mowers.
• Avoid old gas (more than 30 days without stabilizer).
• Avoid E15/E85; higher ethanol blends can cause hard starting and fuel-system issues.
• Do not mix oil into the gas; this mower uses a 4-cycle engine (oil goes in the crankcase, not the fuel).

Quick fuel checklist for 917388110

Item	Recommended	Notes
Gas type	Regular unleaded	Most reliable choice for small engines
Ethanol content	E0 to E10	E10 is common; avoid higher blends
Fuel freshness	Fresh	Replace stale fuel before troubleshooting
Storage	Stabilizer + sealed can	Helps prevent varnish and starting problems

If the mower was stored with fuel in it

• Drain and replace the fuel if it smells sour or looks dark.
• Add fuel stabilizer to fresh gas for storage.
• If it still will not start, check the basics: air filter condition, spark plug condition, and that the primer and control bar are used correctly.

Why it matters

Correct fuel helps prevent carburetor varnish, hard starting, surging, and loss of power. Fresh regular unleaded gas is the simplest way to keep the Craftsman 917388110 running consistently.

For model-specific operating and fueling notes, follow the 917388110 owner's manual.
