Craftsman 917388541 gas walk-behind lawn mower Parts

The most common problems we see on the Craftsman 917388541 gas walk-behind lawn mower are starting issues, poor cutting performance, and drive or control problems caused by normal wear, debris buildup, or loose hardware. Use the 917388541 owner's manual for model-specific adjustments and maintenance intervals.

Common symptoms and what usually causes them

• Won’t start or starts then dies: stale fuel, dirty air filter, fouled spark plug, or a sticking safety/control cable
• Cuts unevenly or leaves strips: dull/bent blade, debris packed under the deck, or incorrect cutting height setting
• Excess vibration: damaged blade, loose fasteners, or a worn blade adapter
• Self-propel/drive feels weak (if equipped): cable out of adjustment, worn drive components, or binding wheels
• Handle or height adjuster won’t stay set: worn knobs, springs, or loose brackets

Quick checks we recommend (before buying parts)

1. Disconnect the spark plug wire and tip the mower safely (carburetor and air filter side up).
2. Clean packed grass from under the deck and around the blade area.
3. Inspect the blade and blade mounting; check the adapter for rounding or cracking.
4. Verify control cables move freely and return fully; replace a stretched or kinked cable if needed.
5. Tighten handle and wheel hardware; vibration often comes from looseness.

For the Craftsman gas walk-behind lawn mower model 917388541, use fresh regular unleaded gasoline; in most areas, E10 (up to 10% ethanol) is the right choice. Avoid premium fuel unless your manual specifically calls for it, and never use E15 or E85.

What to use (and what to avoid)

• Use regular unleaded from a busy station (fresher fuel).
• Use E10 or less ethanol content.
• Use fresh fuel (best within about 30 days, or stabilized for storage).
• Avoid E15 and E85 (higher ethanol blends can cause hard starting and fuel-system issues).
• Avoid old gas that smells sour or looks dark.

Quick fuel guide

Fuel type	OK for most mowers	Notes
Regular unleaded (ethanol-free)	Yes	Best for storage and fewer fuel issues
Regular unleaded E10	Yes	Common and typically recommended
Premium (higher octane)	Usually not needed	Octane does not add power in small engines
E15	No	Can run lean and damage fuel components
E85	No	Too much ethanol for small engines

Best practices for fewer starting problems

• Fill with fresh gas and keep the cap tight.
• If the mower will sit more than a few weeks, add fuel stabilizer and run the engine briefly to pull treated fuel into the carburetor.
• Store gas in an approved container, out of heat and sunlight.
• If the mower won’t start after sitting, drain old fuel and refill before replacing parts.

Why it matters

Correct fuel helps your Craftsman mower start easier, run smoother, and reduces carburetor varnish, clogged jets, and fuel-line deterioration that can lead to no-start or surging.
