What engine is in the Briggs and Stratton 461707-0145-E3?
The Briggs 461707-0145-E3 is the engine model itself; it identifies a specific Briggs single-cylinder, vertical-shaft lawn and garden engine configuration used on many riding mowers and lawn tractors. For parts and service, match everything to the exact 461707-0145-E3 code on the engine label.
How to confirm you have the right engine code
We recommend reading the engine’s ID stamp or label and matching all three fields (model, type, code). This prevents ordering the wrong carburetor, ignition, or starter parts.
- Find the model-type-code on the blower housing, valve cover, or a stamped metal tag
- Clean the area so every digit is readable
- Match the full string exactly, including the dash and suffix (E3)
- Use the engine code to confirm the correct parts list for your build date
- If the tractor has a separate tractor model number, do not use that for engine parts
Common parts that must match the exact engine model
Even within the 461707 family, ignition and starting components can vary by type and code. These are common “must match” items:
| System | What can differ by type/code | Example part on this model page |
|---|---|---|
| Ignition | Coil style, kill-wire routing, air gap spec | Briggs & statton armature 590781 |
| Starting | Starter motor, pinion gear tooth count | Briggs & stratton lawn & garden equipment engine starter motor 497596 |
| Air intake | Air cleaner base/cover design | Briggs & statton element 272490S |
| Fuel | Hose routing, clamp size | Briggs & statton hose clamp 791850 |
Why it matters
Using the exact 461707-0145-E3 identification avoids no-start issues, misfit parts, and repeat repairs, especially for ignition coil, starter gear, and air cleaner components.

What model number is the Briggs and Stratton 17.5 hp engine?
For your Briggs lawn and garden engine, the model number is the full engine type code stamped on the blower housing. On this page, the engine model is 461707-0145-E3; “17.5 HP” is a horsepower rating used across multiple Briggs engines, so the exact model depends on the code on your engine.
How to identify the correct Briggs model number
Look for the stamped code on the engine (not the tractor). On most Briggs vertical-shaft engines, it’s on the blower housing or valve cover area.
- Clean the area so the numbers are readable
- Record the full Model-Type-Code (all digits and dashes)
- Match the model exactly (example: 461707-0145-E3)
- Use the type number to confirm the correct carburetor, ignition, and starter parts
- Use the code number to confirm the correct production version
Why “17.5 HP” alone is not enough
Briggs used the 17.5 HP rating on many Intek-style and other vertical-shaft engines over multiple years. Two engines can both be 17.5 HP but use different starters, ignition coils, air filters, and fuel system parts.
Quick comparison
| What you have | What it tells you | What we use for parts matching |
|---|---|---|
| 17.5 HP label | Approximate power class | Not specific enough |
| Model-Type-Code stamp | Exact engine build | Correct identifier |
| Model 461707-0145-E3 | Specific engine family/version | Best match for this page |
Parts that commonly depend on the exact model/type
Once you confirm the stamped model, we match the right maintenance and repair parts, such as:
- Air filter and pre-filter (air cleaner element)
- Fuel pump and vacuum hose
- Ignition coil (armature)
- Starter motor and starter gear
- Electrical terminals and wire harness
If you’re doing a tune-up on model 461707-0145-E3, common service items include the Briggs & statton filter 394358S and the Briggs & statton element 272490S.
Why it matters
Using the exact Briggs model-type-code prevents ordering the wrong starter, ignition, or fuel parts, and it also speeds up troubleshooting for no-start, hard-start, and poor-running symptoms.

Where is the model number on a Briggs and Stratton Intek engine?
On a Briggs Intek engine, the model number is printed on the engine’s identification label (often called the model-type-code tag) mounted directly on the engine shroud, valve cover area, or blower housing. For model 461707-0145-E3, you will see three numbers: model, type, and code.
Where to look on the engine
We recommend checking these common tag locations first (clean the area if needed):
- On top of the engine cover (blower housing) near the recoil starter or air intake
- On the valve cover area (often on V-twin engines)
- On the side of the engine shroud near the muffler or carburetor
- Stamped into metal on some engines (less common than a printed label)
How to read the numbers (model, type, code)
Briggs engines typically show three fields on the tag:
- Model: identifies the engine family (this is the “model number” most parts lookups use)
- Type: identifies the exact configuration within that model (governor, crankshaft, carb setup)
- Code: the production date code used to match running changes
| What you see on the tag | What it means | Why we use it |
|---|---|---|
| Model | Engine family identifier | Gets you into the correct parts breakdown |
| Type | Configuration identifier | Ensures the right carb, ignition, and starter parts |
| Code | Build date code | Helps match updated parts and revisions |
Why it matters for ordering parts
Using all three numbers helps us match the correct Briggs parts for your exact build, especially for ignition, fuel, and starting components.
- Air intake and filtration parts can vary by type
- Starter systems can vary by type and code
- Ignition parts can change across production runs
If you are troubleshooting a no-start or weak spark condition while identifying the engine, a common related part is the ignition coil, listed for this model as Briggs & statton armature 590781.
