What engine is in the Briggs and Stratton 287707-0255-01?
The Briggs 287707-0255-01 is the engine model itself (a Briggs lawn and garden engine). If you are trying to identify the engine family or a compatible replacement engine, match the full model-type-code stamped on the blower housing and then cross-check the parts list for this model; you can also search by that full number on Sears PartsDirect.
How to confirm the exact engine identification
Use the engine’s stamped ID (typically on the blower housing or valve cover area) and verify all characters.
- Locate the model-type-code stamping on the engine
- Confirm it matches 287707-0255-01 exactly (including dashes)
- Compare key features: vertical shaft vs horizontal shaft, crankshaft diameter/length, and charging system
- If the equipment has a separate mower or tractor model number, keep that handy for fit checks
- Use the parts diagrams for 287707-0255-01 to confirm component style before ordering
Parts that help verify you are on the right engine
If the parts shown for 287707-0255-01 match what you see on your engine, you are identifying it correctly. Common “sanity check” items include filters and ignition parts.
| What you check | What it tells you | Example part on this model page |
|---|---|---|
| Air intake and filter style | Confirms air cleaner base and cover design | Briggs & statton air filter 496894S |
| Oil filter mounting and thread | Confirms lubrication system configuration | Briggs & statton filter 394358S |
| Ignition/charging components | Confirms electrical system type | Briggs & statton armature 591459 |
Why it matters
Briggs engines can look similar across families, but small differences in crankshaft specs, charging output, and carburetor linkage change fit and performance. Matching the full 287707-0255-01 ID helps ensure the right gasket, air filter, and ignition parts for reliable starting and mowing power.

What kind of oil does a Briggs and Stratton 287707-0255-01 take?
For the Briggs 287707-0255-01 lawn and garden engine, we use standard 4-cycle engine oil; 10W-30 is the best all-around choice for most temperatures, and SAE 30 is a common option for consistently warm weather. For oil capacity, most engines in this family hold about 20 oz (check the dipstick fill level). You can also stock up on maintenance items like the Briggs & statton air filter 496894S and order parts on this model’s parts list or through Sears PartsDirect.
Recommended oil type (what to use)
Use 4-stroke small engine oil that meets common automotive standards.
- 10W-30: best for changing temperatures and typical mowing seasons
- SAE 30: best for steady warm weather operation
- Avoid 2-cycle oil (it is not correct for this engine)
- If the engine is used in dusty conditions, keep the oil fresh and the air filter clean
Oil capacity and how to fill it correctly
Because exact capacity can vary by crankcase configuration, we fill by the dipstick level rather than by ounces.
- Park the equipment on level ground
- Shut the engine off and let it cool
- Remove the dipstick, wipe it clean, then reinsert and check
- Add oil slowly, recheck often, and stop at the FULL mark
- Do not overfill; overfilling can cause smoking and hard starting
Typical capacity guide
| Item | What to expect | What to do |
|---|---|---|
| Oil capacity | About 20 oz for many Briggs single-cylinder L-head/OHV mower engines | Fill to the dipstick FULL mark |
| Best “one oil” choice | 10W-30 | Use for most climates |
| Warm-weather option | SAE 30 | Use when temps stay warm |
Why it matters
Correct oil viscosity protects the crankshaft, connecting rod, and valve train during hot operation. Using the wrong oil (or running low) speeds up wear and can cause smoking, knocking, or loss of power.
Helpful maintenance parts for this engine
If you are doing an oil change or tune-up on model 287707-0255-01, these commonly help:
- Briggs & statton air filter 496894S (helps prevent dirt ingestion)
- Briggs & statton filter 394358S (common service filter item)
- Briggs & statton filter 272403S (another filter option listed for this model)

What are common Briggs & Stratton engine problems?
Common problems on the Briggs 287707-0255-01 lawn and garden engine are hard starting, surging, stalling, and loss of power caused by fuel issues, restricted airflow, weak ignition, or charging and wiring faults. Most fixes start with fresh fuel, clean filtration, and basic spark and electrical checks.
Most common symptoms and what they usually mean
- Won’t start or starts then dies: stale fuel, dirty carburetor passages, plugged fuel inlet fitting, weak spark
- Surges at idle or hunts: partially clogged carburetor, air leak at intake, restricted air filter
- Runs rough or lacks power: dirty air filter, low compression, valve train issues, fouled plug
- Backfires or kicks back while starting: sheared flywheel key, ignition timing shifted
- No charge or intermittent electrical: stator/armature issues, damaged harness, bad connections
Quick checks we recommend first (fast, low-cost)
- Drain old fuel and refill with fresh fuel (especially after storage).
- Inspect and replace the air filter if it is dirty or oil-soaked (use Briggs & statton air filter 496894S).
- Check for spark and inspect the ignition lead and boot for damage (the Briggs & statton elbow plug 691909 is a common wear item).
- If the engine backfires or suddenly won’t start after hitting something, inspect the flywheel key (use Briggs & statton key 222698S).
- If you suspect charging problems, test output and wiring before replacing components; the Briggs & statton stator 592831 and Briggs & statton armature 591459 are common charging/ignition-related parts.
Common problem areas and typical fixes
| Problem area | What you notice | Typical fix |
|---|---|---|
| Air intake | Black smoke, bogging, poor power | Replace air filter; clean housing |
| Fuel delivery | Starts on spray, dies under load | Clean carb; replace clogged fittings |
| Ignition timing | Kickback, backfire, no-start | Replace flywheel key |
| Electrical/charging | Battery not charging, weak crank | Test stator/armature; repair wiring |
Why it matters
Small engines like the Briggs 287707-0255-01 are sensitive to airflow and fuel quality. A restricted air filter or stale ethanol-blended fuel can quickly cause hard starting, surging, and plug fouling, and ignoring early symptoms often leads to bigger repairs.

What is the valve clearance on a Briggs and Stratton 287707-0255-01?
On the Briggs & Stratton 287707-0255-01 lawn and garden engine, valve clearance (valve lash) is set in these typical ranges: intake 0.005 to 0.007 in and exhaust 0.009 to 0.011 in. Setting lash correctly prevents hard starting, backfiring, and power loss.
How we check and set valve clearance
- Disconnect the spark plug wire and secure it away from the plug.
- Remove the valve cover; replace the gasket if it tears or won’t reseal.
- Rotate the engine to the compression stroke and bring the piston to top dead center (TDC).
- Turn the crankshaft slightly past TDC (common practice is about 1/4 inch down from TDC) so the compression release is not affecting the setting.
- Slide a feeler gauge between the valve stem and rocker arm.
- Loosen the lock nut, turn the adjuster to the target gap, then tighten the lock nut.
- Recheck the clearance after tightening.
Valve lash spec table
| Valve | Clearance range (in) | If too tight | If too loose |
|---|---|---|---|
| Intake | 0.005 to 0.007 | Hard starting, low compression | Ticking noise, reduced performance |
| Exhaust | 0.009 to 0.011 | Misfire when hot, backfire | Ticking noise, reduced performance |
Parts that commonly come up during this repair
If the cover leaks after reassembly or hardware is damaged, these parts from the list for this model are often useful:
- Gasket 691917 (helps reseal the valve cover or other mating surfaces)
- Hex screw 691061 (replacement fastener if a screw is stripped or missing)
- Briggs & statton lawn & garden equipment engine valve cover kit 495992 (helpful if the cover components are damaged)
If you need additional replacement parts for model 287707-0255-01, use the parts list for this engine or search by model number on Sears PartsDirect.
Why it matters
As the engine heats up, valves expand. Correct lash ensures the valves fully close for proper compression and combustion, which directly affects starting, idle quality, and power under load.
