Craftsman 917388511 gas walk-behind lawn mower Parts

For the Craftsman 917388511 gas walk-behind lawn mower, we recommend using fresh regular unleaded gasoline (87 octane). Higher octane (like 91) does not add power in a mower engine; the bigger priority is clean, fresh fuel and correct starting and storage practices from the 917388511 owner's manual.

• Use fresh, regular unleaded 87 octane from a clean fuel can.
• Avoid stale fuel (old gas is a top cause of no-start issues).
• Avoid fuel contaminated with water or dirt.
• Do not store gasoline from one season to the next.
• Keep gasoline off finished surfaces and wheels; wipe spills promptly.

The manual’s troubleshooting points to fuel quality and ignition basics first. Check these in order:

• Confirm you have fuel in the tank and it is fresh.
• Make sure the spark plug wire is connected.
• Check for stale fuel or water in fuel.
• Inspect the air filter for dirt restriction.
• If you suspect a blade issue, check for a loose blade or broken blade adapter (a common no-start cause listed in the manual); the lawn mower blade adapter 581547901 is the model-matched part.

Using 87 octane keeps operation consistent and cost-effective, but fuel freshness is what most often prevents hard-start and no-start problems. Good storage habits also help protect the engine and reduce carburetor issues over time.

On the Craftsman walk-behind mower model 917388511, the model and serial numbers are printed on a decal on the rear of the lawn mower housing (the back of the mower deck). Use that decal information when ordering parts or checking specifications in the 917388511 owner's manual.

Check these common spots first (in this order):

• Rear of the mower housing (deck): look for a decal with the model and serial number.
• Back edge of the deck near the discharge area: sometimes the decal is slightly offset.
• Top of the deck behind the engine: wipe off grass and dust to reveal the label.
• Underside of the handle crossbar area: occasionally the decal is placed where the handle mounts.

Most Craftsman mower ID decals include:

• Model number (for this unit: 917.388511, often shown with a dot)
• Serial number
• Date of purchase fields (sometimes on the manual page, not the decal)

• Clean the area with a damp rag and mild soap; dry it fully.
• Use a flashlight at an angle to make faded printing easier to see.

Using the exact model number prevents ordering the wrong blade, belt, wheel, or control cable; small design changes can affect fit even within the same Craftsman mower family.
