Craftsman 917376733 lawn mower Parts

For the Craftsman walk-behind mower model 917376733, use fresh regular unleaded gasoline (87 octane) for normal mowing. Using 91 octane does not improve power in typical small engines; fuel freshness and correct storage practices matter most. See the fuel and storage guidance in the 917376733 owner's manual.

What to use (and what to avoid)

• Use 87-octane regular unleaded from a clean, approved fuel can.
• Use fresh fuel; old gas causes hard starting and rough running.
• Avoid fuel contaminated with water, dirt, or rust.
• Do not rely on premium fuel to fix performance issues; address maintenance items instead.
• For storage, follow the manual’s cautions about handling gasoline and storing the mower.

87 vs 91: what changes in a mower engine

Fuel choice	What it does in most mower engines	When to choose it
87 octane (regular)	Correct everyday fuel	Routine mowing and normal temperatures
91 octane (premium)	No added power or smoother running by itself	Only if the engine manufacturer specifically calls for it

Why it matters

Most walk-behind mower engines are designed to run on regular unleaded fuel. The bigger risk to the carburetor and starting system is stale or contaminated gasoline, especially when the mower sits between uses or over the off-season.

Fuel handling and storage basics

• Buy only what you can use within 30 days.
• Store gasoline in a sealed, clean container; replace cans that start to rust.
• Keep the fuel cap area clean before refueling to prevent debris from entering the tank.
• Let the engine cool before storing the mower, especially indoors.

A Craftsman mower described as “6.75” is usually identified by the model number printed on the mower’s rear housing decal, not by the engine label. For the Craftsman rotary mower covered by this page, the model number is 917.376733 (often written without the dot as 917376733).

How to find the model number on your mower

We recommend matching the mower’s model number from the equipment decal (rear of the mower housing), then using that number to look up parts and the correct owner’s manual.

• Look on the rear of the mower housing for the model/serial decal.
• Record both the model number and serial number.
• Ignore engine-only numbers; the Briggs & Stratton engine series is not the mower model.
• If the decal is dirty, wipe it clean and use a flashlight to read stamped/printed characters.
• Use the exact model number format you see (with or without the dot).

Model number vs. engine series (quick comparison)

What you see	What it identifies	Example on this mower
Mower model number	The complete Craftsman walk-behind mower	917.376733
Engine series/HP label	The engine family, not the mower	650 Series

Why it matters

The model number controls the correct parts list and diagrams for your Craftsman walk-behind mower. For example, drive and wheel hardware can vary by model; using the right model number helps you select the correct items like the lawn mower drive control cable 532407816 and related fasteners.

Helpful next step

Use the 917376733 owner’s manual to confirm the model/serial decal location and to follow the correct maintenance and parts identification guidance.

On the Craftsman walk-behind mower model 917376733, the mower model number is printed on the product identification label, and the engine model number is stamped on the engine itself. For parts and diagrams, we use the mower model number 917376733 shown in the 917376733 owner's manual.

Where to look (mower vs. engine)

• Mower model number (917376733): check the mower’s ID label on the deck or rear housing area.
• Engine model number: look for a stamped code on the Briggs & Stratton engine shroud or metal tag.
• Engine family used on this mower: the manual shows a Briggs & Stratton engine model 124T02-0736-EA.
• Why it matters: mower parts (wheels, cables, bag) match the mower model; engine parts (carburetor, recoil starter) match the engine model.

Quick identification checklist

• Clean grass and dirt off the deck and engine shroud so the label and stamp are readable.
• Write down the full model string exactly as shown (letters, numbers, dashes).
• Use the mower model number when ordering chassis parts like the lawn mower drive control cable 532407816.
• Use the engine model number when ordering engine-specific parts (spark plug, air filter, carburetor parts).

Which number should I use for common repairs?

Repair or part type	Use this number	Example on 917376733
Drive system, wheels, height adjusters	Mower model number	917376733
Blade, bagging, rear door, deck hardware	Mower model number	917376733
Fuel/ignition/compression, recoil starter	Engine model number	124T02-0736-EA

Why it matters

Using the correct model number prevents ordering the wrong part. Craftsman walk-behind mowers often share similar decks, but small differences in cables, wheels, and hardware can change by model and engine configuration.
