How to find Briggs & Stratton engine parts?
To find the right parts for your Briggs 98902-0404-02 lawn and garden engine, we match parts by the exact engine model and type code, then cross-check the part name and part ID in the parts list. This prevents ordering look-alike parts that do not fit.
Step-by-step: how we recommend finding the correct part
- Confirm the full engine model number on the engine shroud or ID tag (use 98902-0404-02 exactly).
- Write down any additional engine identification numbers shown with the model (type and code are common on Briggs engines).
- Identify the system you are repairing (fuel, ignition, starter, seals, gaskets).
- Use the parts list for model 98902-0404-02 to locate the matching part name and part ID.
- Compare your old part to the listing (mounting holes, connector style, shaft size, gasket shape).
- Order the exact match; for example, a no-start issue may point you to the Briggs & statton primer 694394 or the Briggs & statton switch 692310.
Common parts people look for on this engine
| Repair need | What to look up | Example part on this model |
|---|---|---|
| Engine will not prime or starts then dies | Primer bulb and fuel delivery parts | Briggs & statton primer 694394 |
| No spark or engine will not shut off | Stop/kill switch and wiring | Briggs & statton switch 692310 |
| Flywheel service or timing issues after impact | Flywheel key | Briggs & statton key 222698S |
| Fuel leaks or cracked tank | Fuel tank | Briggs & statton lawn & garden equipment engine fuel tank 494406 |
Why it matters
Briggs engines often have multiple versions that look similar. Matching the exact 98902-0404-02 identification and then selecting the correct part ID (for example, 694394 vs. other primer styles) helps ensure proper fit, safe operation, and reliable starting.

How do I identify my Briggs and Stratton model?
To identify your Briggs engine model, find the engine ID plate and read the three-part number set: model, type, and code. For your engine, the model number format looks like 98902-0404-02, and each section helps match the correct parts.
Where to find the model, type, and code
On most Briggs lawn and garden engines, the identification numbers are stamped or printed on an engine ID plate (or directly on the blower housing). Common locations include:
- Above the spark plug area on the valve cover or blower housing
- Near the muffler heat shield
- On the recoil starter housing (pull-start shroud)
- On the engine block near the flywheel
How to read the numbers
Briggs engines typically use three identifiers:
- Model: the base engine family (used to select the correct illustrated parts list)
- Type: the exact configuration (carburetor, governor linkages, crankshaft style, etc.)
- Code: the production date code (used to match running changes)
Quick reference table
| What you see on the plate | What it means | Why you need it |
|---|---|---|
| Model | Engine family | Gets you to the right parts breakdown |
| Type | Configuration | Ensures the part fits your exact build |
| Code | Build date | Helps match updated or superseded parts |
Why it matters when ordering parts
Using only the model number can still leave room for mismatches because the type and code can change small but important details. When you match all three, you get the right parts the first time, especially for fuel and ignition items.
Parts that commonly require an exact match
When you are shopping parts for Briggs model 98902-0404-02, these are the kinds of parts where model, type, and code matter most:
- Carburetor and fuel system parts (example: Briggs & statton lawn & garden equipment engine carburetor 498809)
- Primer and starting components (example: Briggs & statton primer 694394)
- Ignition and safety shutoff parts (example: Briggs & statton switch 692310)
- Flywheel-related parts (example: Briggs & statton key 222698S)

How do I find the specs for my Briggs & Stratton engine?
For your Briggs 98902-0404-02 lawn and garden engine, the most reliable way to get the correct specs is to use the engine’s exact model, type, and code from the ID tag, then match those numbers to the correct parts breakdown and service information for that exact build.
Where to find the engine ID numbers
On Briggs engines, the ID is typically stamped or printed on the blower housing, valve cover area, or near the muffler heat shield. Record all numbers exactly.
- Model number (for this page: 98902-0404-02)
- Type number (identifies the configuration)
- Code number (identifies the production date/build)
- Any spec or trim numbers shown on the tag
What “specs” you can confirm from the parts list
Even without a manual on this page, you can still confirm many practical specs by matching your engine build to the correct parts used on it.
- Fuel system style (primer bulb vs. other setup)
- Ignition shutoff style (switch and wiring style)
- Carburetion components (diaphragm vs. other designs)
- Starter system components (recoil parts)
- Seals and gaskets used on your exact build
If your engine uses a primer bulb, the replacement primer shown for this model is the Briggs & statton primer 694394.
Quick “specs” checklist for troubleshooting
Use this checklist when you are trying to identify what you need (tune-up, no-start, fuel leak, hard starting).
- Hard starting or only runs on choke: inspect fuel tank, fuel line, and carburetor diaphragm
- No spark or won’t shut off: inspect the stop switch and kill wire routing
- Recoil won’t pull or slips: inspect starter cup and recoil clutch components
- Fuel leak: inspect tank and seals
- Backfire or sudden no-start after impact: inspect flywheel key
Common parts that help identify the configuration
| What you’re checking | Part example on this model | What it tells you |
|---|---|---|
| Primer-style fuel assist | Primer 694394 | Confirms primer-equipped setup |
| Carburetor design | Carburetor 498809 | Helps match fuel system configuration |
| Flywheel alignment | Key 222698S | Helps diagnose timing shift after impact |
| Fuel storage | Fuel tank 494406 | Confirms tank style and mounting |
Why it matters
Briggs engines often share the same model family but differ by type and code; using the full ID prevents ordering the wrong carburetor, gasket, or ignition parts and speeds up no-start and fuel-system troubleshooting.

Can I use 10W30 in my Briggs and Stratton engine?
Yes. For a Briggs & Stratton lawn and garden engine like model 98902-0404-02, SAE 10W-30 is a standard, widely used viscosity for normal mowing-season temperatures; synthetic 5W-30 or 10W-30 also works well. The key is using the correct oil level and changing it on schedule.
Choosing the right viscosity by temperature
Use this as a practical guide for small 4-cycle lawn and garden engines.
- Below 40°F: 5W-30 (synthetic preferred for easier starting)
- 40°F to 90°F+: 10W-30 (common all-around choice)
- Hot, heavy use: synthetic 10W-30 (better stability under heat)
- Frequent cold starts: 5W-30 reduces startup wear
| Condition | Recommended viscosity | Why it matters |
|---|---|---|
| Cold weather starting | 5W-30 | Faster lubrication at startup |
| Typical spring and summer use | 10W-30 | Strong protection at operating temp |
| High heat, long run times | Synthetic 10W-30 | Resists thinning and breakdown |
Oil-change tips that prevent problems
Oil viscosity rarely causes running issues by itself; oil level and basic maintenance matter more.
- Check oil on level ground; keep it at the full mark (do not overfill)
- Change oil more often in dusty conditions or heavy use
- If the engine suddenly backfires or will not start after a hard stop, inspect ignition timing components
If you suspect a timing issue after impact or a sudden stop, a sheared flywheel key is a common cause; see the replacement Briggs & statton key 222698S.
Why it matters
Correct viscosity helps your engine lubricate quickly at startup and maintain a protective oil film when hot, reducing wear on internal parts like the crankshaft, bearings, and cylinder.
