How to decode briggs and stratton engine model number?
On a Briggs lawn and garden engine like model 311707-0132-E1, the ID is typically split into three fields: Model, Type, and Code. The model identifies the engine family, the type narrows the exact configuration, and the code is the build date information.
What each section means
- Model: Basic engine series and key specs (family, displacement class, design).
- Type: The exact version within that model (carburetor, governor, crankshaft, starter/charging setup).
- Code: Manufacturing date code used to match the correct parts and service updates.
Example using your model number
For 311707-0132-E1:
| Field | Value | What it tells us |
|---|---|---|
| Model | 311707 | Engine family/series |
| Type | 0132 | Exact configuration |
| Code | E1 | Suffix/revision identifier used for parts matching |
Why decoding matters for parts
Using the full model and type helps us match the correct tune-up and repair parts for your exact engine build. For example, air and fuel system parts can vary by type even when the model family is the same.
Common parts that often depend on the full ID:
- Air filter and pre-cleaner
- Fuel line routing and diameter
- Ignition armature and wiring
- Carburetor and intake fittings
- Head gasket and valve train components
Parts you may match by model and type
If you are doing maintenance on 311707-0132-E1, these model-matched parts are commonly replaced:
- Briggs & statton air filter 496894S
- Briggs & statton fuel line 791766
- Briggs & statton armature 591459

How do I find the specs for my Briggs & Stratton engine?
For your Briggs 311707-0132-E1 lawn and garden engine, the most reliable way to get exact specs (tune-up settings, valve clearances, bore and stroke, and service limits) is to use the engine model and type code from the ID label, then match those numbers to the correct spec/repair information.
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. You are looking for:
- Model (example: 311707)
- Type (example: 0132)
- Code (a date-style production code)
- Sometimes a trim or additional suffix (example: E1)
What specs you can pull from the model and type
Once you have the full model and type (for example, 311707-0132-E1), you can identify the correct specification set for items such as:
- Valve clearance settings (intake and exhaust)
- Spark plug type and gap
- Oil type and crankcase capacity
- Governor and idle RPM targets
- Bore and stroke, compression-related specs
- Carburetor and fuel system configuration
Quick checklist: what to record before you look up specs
Write these down exactly as shown on the engine label so you land on the right spec sheet:
- Model: 311707
- Type: 0132
- Code: (all digits)
- Any suffix: E1
Common “spec lookup” outcomes (what changes and what doesn’t)
Some specs are consistent across an engine family, while others vary by type code. Use this as a guide:
| Spec item | Usually tied to | Why it varies |
|---|---|---|
| Valve clearance | Type code | Cam, head, and valve train variations |
| Carburetor details | Type code | Emissions and fuel system versions |
| Oil capacity | Model family | Sump and crankcase design |
| Ignition parts | Type code | Armature and flywheel pairing |
Why it matters
Using the exact specs for your 311707-0132-E1 prevents hard starting, surging, backfiring, and premature wear. It also helps you choose the right maintenance parts for your engine configuration.
Related parts you may replace during a tune-up
If you are gathering specs because the engine is running poorly, these common maintenance parts are often involved:
- Briggs & statton air filter 496894S (restricted airflow can cause rich running)
- Briggs & statton fuel line 791766 (cracks or leaks can cause surging)
- Briggs & statton armature 591459 (weak spark can mimic fuel problems)

How do I tell what HP my Briggs and Stratton engine is?
For your Briggs 311707-0132-E1 lawn and garden engine, we identify horsepower by checking the engine’s power label (often on the blower housing, valve cover, or near the muffler) for an HP, cc, or torque rating. If the label is missing, we use the model-type-code numbers to look up the original rating.
Where to find the horsepower information
Check these common locations first:
- Blower housing (recoil starter shroud)
- Valve cover area
- Near the muffler or heat shield
- On the engine shroud near the spark plug
- On a decal near the carburetor or air cleaner
If you see cc (cubic centimeters) instead of HP, that is still useful for identifying the engine family and typical power range.
If the label is gone: use the model-type-code
Briggs engines are commonly identified by a Model, Type, and Code stamped into the metal (not just a sticker). For model 311707-0132-E1, the model number is already known; the Type and Code help confirm the exact build and original power rating.
Quick lookup checklist
- Clean the stamping area with a rag and flashlight
- Write down the full string (Model, Type, Code)
- Match the numbers to the correct parts list and engine spec
A dirty air cleaner or fuel delivery issue can also make an engine feel “low HP,” so it is worth checking maintenance items while you are identifying the engine.
Common maintenance parts that affect performance
If the engine bogs, surges, or lacks power, these parts are frequent culprits:
- Briggs & statton air filter 496894S (restricted airflow reduces power)
- Briggs & statton fuel line 791766 (cracks or soft spots can starve fuel)
- Briggs & statton filter 394358S (dirty filter can limit fuel flow)
Typical label terms and what they mean
| What you see on the engine | What it tells you |
|---|---|
| HP | Gross horsepower rating (marketing spec) |
| Torque (ft-lb) | Power rating often used on newer labels |
| cc | Engine displacement; helps estimate typical power range |
Why it matters
Knowing the correct HP (or torque) helps us match the right carburetor, ignition parts, and tune-up items for the exact 311707-0132-E1 build, and it prevents ordering parts that fit a similar looking engine but a different Type/Code.

How many cc's is a 13 horse Briggs & Stratton?
A “13 HP Briggs & Stratton” label does not point to one exact displacement; different engine families share similar horsepower ratings. If you are working with Briggs & Stratton model 311707-0132-E1, that engine is a 500 cc single-cylinder engine (commonly marketed around the 17 HP class), so it is not a 13 HP engine.
Quick way to match the right cc to your engine
Horsepower is a marketing rating; the model number is the reliable identifier for displacement and parts fit.
- Find the engine stamping or tag and confirm it reads 311707-0132-E1
- Use the model number to select the correct carburetor, ignition, and filters
- If the equipment was repowered, trust the engine tag on the engine, not the mower or tractor label
Typical displacement ranges (when you truly have a 13 HP engine)
If your engine is actually a 13 HP Briggs & Stratton (different model than 311707-0132-E1), most fall into these common displacement bands:
- Single-cylinder OHV: about 350 to 400 cc
- Older L-head (flathead): about 390 to 420 cc
- Commercial variants: often 400 cc and up
Parts that help when “13 HP” questions come from low power
Low power, surging, or hard starting is often caused by air, fuel, or ignition issues. For model 311707-0132-E1, common maintenance and tune-up parts include:
- Air restriction: Briggs & statton air filter 496894S
- Fuel delivery: Briggs & statton fuel line 791766
- Spark and ignition: Briggs & statton armature 591459
Quick reference table
| What you know | What it tells you | Best next step |
|---|---|---|
| “13 HP” on a label | Power class only | Identify the engine model number |
| 311707-0132-E1 | 500 cc engine family and correct parts match | Order parts by model-specific diagrams |
Why it matters
Ordering by horsepower alone often leads to the wrong carburetor, air filter, or ignition parts. Using the exact model number (like 311707-0132-E1) locks in the correct displacement and ensures proper fit.
