Craftsman 917288520 tractor Parts

On the Craftsman 917288520 riding lawn tractor, we clean the carburetor without removing it by safely accessing the air-intake throat, spraying carburetor cleaner in short bursts, and clearing debris from linkages and the bowl area. This improves starting and idle when varnish and dirt are minor.

• Park on a flat surface, set the parking brake, and let the engine cool.
• Remove the key and disconnect the spark plug wire to prevent accidental starting.
• Work outdoors or in a well-ventilated area; carb cleaner fumes are strong.
• Keep rags handy; overspray can loosen grime that needs wiping.
• Have a new air filter ready if yours is dirty or oil-soaked.

For control locations and air cleaner removal on this model, follow the 917288520 owner's manual.

1. Remove the air cleaner assembly so you can see the carburetor throat.
2. Clean the exterior first: brush off loose grass and dust around the carb body, throttle linkage, and choke linkage.
3. Spray carb cleaner into the throat (where air enters) in short bursts.
4. Move the throttle and choke by hand (engine off) to help cleaner reach sticky pivot points.
5. If it will run: reconnect the spark plug wire, start the engine, and lightly spray into the throat while it idles (do not flood it). Then shut it down and reinstall the air cleaner.
6. If it will not run: spray, wait 5 to 10 minutes, then try starting again. Repeat once.

A riding mower carburetor has small fuel passages that gum up quickly with old fuel. In-place cleaning is a fast first step; it often restores normal idle and throttle response without removing the carburetor.

On a Craftsman riding mower like model 917288520, a “bad carburetor” usually shows up as hard starting, needing choke to keep running, surging or bogging under load, and poor throttle response that does not improve with adjustment. Confirm the basics (fresh fuel, spark, airflow) before replacing parts.

• Engine starts only with choke, then dies when choke is opened
• Bogging or hesitation when you advance the throttle
• Surging (hunting up and down) at steady throttle
• Hard starting after sitting, even with a charged battery
• Black smoke or fuel smell (running rich) or popping/backfiring (running lean)
• Carb adjustments make little or only short-term improvement

Many “carb” complaints are caused by fuel quality, ignition, or air restriction. We check these in order:

1. Fuel: Drain old gas; refill with fresh fuel. Replace a dirty in-line fuel filter if equipped.
2. Air filter: Clean or replace; a clogged filter makes the engine run rich and bog.
3. Spark: Inspect/replace spark plug; verify strong spark.
4. Choke/throttle linkage: Make sure the choke plate fully opens and closes.
5. Vacuum leaks: Check intake gaskets and mounting bolts for looseness.

For model-specific maintenance intervals and adjustment locations, use the 917288520 owner’s manual.

A restricted or worn carburetor can make the engine run lean (overheating, poor power) or rich (fouled plug, heavy fuel use). Catching the real cause early prevents repeated no-starts and rough mowing performance.

Fixing a carburetor on a Craftsman riding tractor like model 917288520 is usually a moderate DIY job: cleaning and adjusting is straightforward, but a full rebuild takes patience, careful part handling, and basic mechanical skill. Most “carb problems” are actually fuel, air, or linkage issues you can correct first.

Before you plan a rebuild, we recommend checking the basics listed in the 917288520 owner's manual. Many running issues come from maintenance items rather than a failed carb.

Common carb-related tasks (easiest to hardest):

• Drain old fuel and refill with fresh fuel
• Clean or replace the air filter (restricted airflow mimics carb trouble)
• Clean the carb bowl and main jet (varnish from stale fuel is common)
• Replace the bowl gasket or needle and seat (if it floods or leaks)
• Rebuild the carburetor (multiple seals, jets, and adjustments)
• Replace the carburetor (fastest when internal passages are badly corroded)

Do these first because they often solve “won’t start” or “runs rough” complaints:

• Verify the choke plate moves fully and is not sticking
• Confirm the throttle linkage and governor springs are connected correctly
• Check for fuel flow from the tank to the carb (clogged fuel line or filter)
• Inspect the spark plug condition (a fouled plug can look like a fuel issue)
• Make sure the engine is getting air (dirty filter, blocked intake)

A carburetor that is dirty or leaking can cause hard starting, surging, stalling under load, black smoke, or fuel smell. Addressing fuel quality and airflow first prevents repeat problems and helps the engine run reliably.

The model number for this Craftsman front-engine lawn tractor is 917288520. You will typically find 917288520 on the product identification label (often under the seat, on the frame rail, or near the engine area); match that number when ordering parts or using the Craftsman 917288520 owner's manual.

Check these common label locations on Craftsman riding mowers and tractors:

• Under the seat pan or on the seat support
• On the left or right frame rail near the rear wheels
• Under the hood near the engine compartment
• Near the steering column or dash support
• On the mower deck housing (less common for the main model label)

Craftsman tractors can look similar across multiple series, but parts like belts, blades, and steering links can vary by model. Using 917288520 helps ensure the correct fit for items such as a blade drive belt, mandrel parts, or electrical components.

If you are replacing a wear item, confirm the part by both the diagram location and the description. For example, the husqvarna lawn tractor blade drive belt 584453101 is a belt option shown for this model’s parts list.

A single digit off in the model number can route you to a different deck size, belt length, or wiring harness; that can cause poor performance, premature wear, or a no-start condition after repair.

Craftsman model 917288520 does not have a single “model year” printed in the model number; Craftsman used the 917-prefix across many years. The reliable way to identify the build timeframe for your exact tractor is to use the serial number and date codes shown on the tractor and engine, then confirm details in the 917288520 owner's manual.

Use the identification labels first; they tie your exact unit to the correct parts diagrams and specifications.

• Locate the model and serial tag (commonly under the seat, on the frame rail, or near the rear fender pan)
• Record the serial number exactly as shown
• Check the engine data plate for the engine model and date code (often the fastest way to narrow the timeframe)
• Note the mower deck size and configuration (deck variations affect belts, blades, and spindles)
• Compare your findings to the identification section in the manual

For many Craftsman riding mowers, the model number identifies a configuration, while the serial number and engine codes identify when your specific unit was built.

The correct timeframe and configuration prevent mismatches when ordering common wear items like a ground drive belt, blade drive belt, and deck spindle components. For example, belt routing and deck hardware can vary by production run; confirming IDs helps you avoid the wrong fit.

If you are servicing the deck, match your deck components to the diagrams before ordering parts such as the lawn tractor mandrel housing 587819701.

On Craftsman riding lawn tractor model 917288520, a carburetor that leaks gas is usually caused by fuel overflowing inside the carburetor (stuck float or worn needle and seat) or by a bad seal where the carburetor mounts to the engine. Use the 917288520 owner's manual for your model’s safety steps and access guidance.

• Stuck float: Float hangs up and never shuts off fuel flow.
• Worn needle and seat: Fuel keeps flowing even when the bowl is full.
• Debris in the carburetor: Dirt or varnish holds the needle open.
• Loose mounting fasteners: Fuel seeps at the intake joint.
• Damaged carburetor gasket: Wetness appears between carburetor and engine.
• Cracked fuel line or loose clamp: Leak looks like it is “from the carb,” but it is running down onto it.

1. Stop the engine immediately and let it cool.
2. Turn the fuel shutoff valve off (if equipped) or clamp the fuel line.
3. Remove the air cleaner cover; look for fuel pooling in the throat or air box.
4. Tap the carb bowl lightly; if dripping changes, the float is sticking.
5. If fuel continues to drip, remove and clean the carburetor; replace worn internal parts and the mounting gasket.

A leaking carburetor can flood the engine, cause hard starting, dilute engine oil with gasoline, and create a fire risk. Fixing the overflow or sealing issue restores proper fuel metering and protects the engine.
