Where is the model number on a Craftsman Weedwacker?
On a Craftsman gas line trimmer like model 316711700, the model number is printed on the trimmer itself, usually on a sticker or metal tag on the shaft, engine housing, or near the handle. Use the number from the tool (not the manual cover) when ordering parts.
Common places to check on a Craftsman trimmer
Look for a label that includes the model number and sometimes a serial number.
- Upper shaft/tube near the throttle handle or clamp area
- Engine housing (recoil starter side or near the muffler area)
- Under or behind the air filter cover area
- Near the fuel tank or on the tank mounting area
- On the debris guard mounting area (less common)
What the label typically looks like
Most Craftsman trimmers use a small decal or tag with a few key fields.
| Label field | What it means | Why you need it |
|---|---|---|
| Model number | Identifies the exact trimmer version | Ensures parts diagrams match your unit |
| Serial number | Production identifier | Helps confirm the correct revision |
| Engine info | Displacement or emissions family (varies) | Useful for tune-up and carburetor matching |
Why it matters for parts and repairs
Craftsman trimmers can look nearly identical across model families, but parts like the cutting head cover, carburetor, and guard assembly can differ by model. Using the exact model number helps us match the right diagrams and avoid ordering the wrong part.
Quick tip before you order parts
- Write the model number exactly as shown (letters, numbers, dashes)
- Take a clear photo of the label for reference
- Use the exploded views in the 316711700 owner's manual to confirm the part location and naming

How big a string trimmer do I need?
For most homeowners, the “right size” string trimmer comes down to power and cutting width. If you have a medium to large yard or thicker weeds, a gas trimmer like Craftsman model 316711700 is the practical choice because it delivers more torque and longer run time than typical corded units.
Quick sizing guide (match the trimmer to the job)
- Small yards and light edging: corded electric (typically 3 to 6 amps)
- Medium yards and mixed grass: battery trimmer (often 40V to 60V class)
- Large yards, heavy weeds, fence lines: gas trimmer (commonly 25cc and up)
- Frequent trimming sessions: choose a setup with easy line loading and a comfortable harness/handle
- Tough brush (not just grass): consider a brush-capable unit (blade-ready) instead of a light-duty string trimmer
What “big” means for a string trimmer
“Bigger” usually refers to these specs; we use them to pick the best fit:
| Spec | What it affects | Typical homeowner range |
|---|---|---|
| Engine size (gas) | Power for thick weeds | 25cc to 30cc+ |
| Cutting swath | How fast you cover ground | 15 to 18 inches |
| Line diameter | Durability in heavy growth | 0.080 to 0.095 inch |
| Weight/balance | Fatigue over time | Lighter is easier, but may cut slower |
How to choose for your yard
- Estimate trimming time: If you trim more than 20 to 30 minutes at a time, gas power is usually more efficient.
- Look at what you cut: Thick weeds and overgrowth need more torque and often a thicker line.
- Prioritize comfort: A slightly heavier trimmer that’s well-balanced can feel easier than a lighter, nose-heavy one.
- Plan for maintenance: Gas trimmers run best with routine tune-ups.
Why it matters
Choosing the right size prevents bogging down in heavy vegetation, reduces re-trimming, and helps avoid premature wear on key maintenance parts like the air filter and spark plug.
Helpful maintenance parts for performance
If your trimmer feels underpowered, basic maintenance often restores cutting strength:

Why is my Craftsman Weedeater not starting?
If your Craftsman gas line trimmer model 316711700 will not start, the most common causes are stale fuel, a restricted air supply, or weak ignition. Start with quick checks you can do in minutes, then move to the air filter, spark plug, and carburetor fuel delivery.
Quick no-start checklist (fastest wins)
- Confirm the stop switch is in the ON/RUN position.
- Use fresh fuel mix (most 2-cycle trimmers run best on fresh mix; old fuel can prevent starting).
- Prime the bulb several times; you should see fuel moving.
- Set the choke correctly for a cold start, then open it as the engine tries to fire.
- Check that the trimmer head is not jammed; a bind can make starting harder.
Air, spark, and fuel: what to check next
A no-start condition usually comes down to one of these three basics.
- Air: A clogged filter can make the engine run overly rich (too much fuel, not enough air). Replace the mtd lawn and garden equipment engine air filter 753-05254 if it is dirty, oil-soaked, or falling apart.
- Spark: Remove and inspect the plug. If it is fouled, damaged, or the electrode is worn, replace the spark plug 794-00082.
- Fuel delivery: If you have spark and a clean filter but it still will not start, the carburetor may be gummed up from old fuel. Replacing the line trimmer carburetor 753-08174 is a common fix; also inspect gaskets and fuel lines for leaks or cracks.
Symptoms and likely causes
| Symptom | Most likely cause | What we recommend |
|---|---|---|
| Won’t pop at all | No spark or no fuel | Check plug first, then prime/fuel flow |
| Pops once, then dies | Choke setting, stale fuel, dirty carb | Fresh fuel; verify choke; consider carb service |
| Starts only with starting fluid | Fuel delivery problem | Carburetor and gaskets inspection |
| Strong fuel smell | Flooded or restricted air | Open choke; check air filter; pull-start with throttle open |
Why it matters
A trimmer that will not start is usually telling you the engine is not getting the right air-fuel mix or spark at the right time. Fixing the root cause prevents repeated flooding, hard starting, and premature wear on the recoil starter.
