How to look up chainsaw serial number?
On the Craftsman chainsaw model 358350811, the serial number is typically stamped into the engine housing or crankcase on a flat spot near the muffler area. Once you find it, record it exactly as shown (letters, numbers, and any dashes) for parts lookup and service.
Where to find the serial number on a gas chainsaw
We most often see the serial number in one of these places:
- On the engine housing or crankcase, on a flat surface near the muffler
- On a label or stamped plate on the rear handle area
- Near the starter housing (recoil starter side)
- On the underside of the saw body where the housing is flat
- Occasionally on the bar-mount area near the clutch cover
For diagrams and model identification details, use the 358350811 owner's manual.
How to write it down so it works for parts lookup
Serial numbers can be easy to misread, so we recommend:
- Clean the area first (wipe off oil and sawdust)
- Use a flashlight and look at the stamp from an angle
- Copy every character in order (including leading zeros)
- Take a photo so you can zoom in later
- Record the model number 358350811 separately from the serial number
Model number vs. serial number (quick comparison)
| Item | What it identifies | Used for |
|---|---|---|
| Model number | The product design and parts list | Ordering the correct parts (bar, chain, fuel system, ignition) |
| Serial number | The specific unit and production run | Service history, warranty, and version changes |
Why it matters
We use the model number to match the correct parts breakdown, but the serial number helps confirm the exact production version when there were mid-run changes (common with fuel lines, carburetor setups, and ignition components).

What do L and H stand for on a chainsaw?
On the Craftsman 358350811 gas chainsaw, L and H are the carburetor mixture adjustment screws: L controls the fuel-air mix at low speed (idle and acceleration), and H controls the mix at high speed (full throttle cutting). These settings affect starting, power, and engine temperature.
What each screw does (and what you may also see)
Most chainsaws use three carb-related adjustments:
- L (low): mixture for idle, off-idle response, and acceleration
- H (high): mixture for high RPM and cutting power
- T or LA (idle speed): sets idle speed (how fast the engine runs with the trigger released)
For your model’s exact adjustment procedure and baseline settings, follow the Craftsman 358350811 owner's manual.
Safe, practical tuning guidelines
Carb adjustments can change how hot the engine runs and how the chain behaves at idle. We recommend these basics:
- Warm the engine before fine-tuning.
- Set idle so the engine runs smoothly without the chain moving.
- If it bogs or dies when you squeeze the throttle, the L circuit is usually involved.
- If it screams, lacks power in the cut, or runs unusually hot, the H circuit is usually involved.
- Make small changes and re-test after each adjustment.
Quick symptom-to-screw reference
| What you notice | Most likely adjustment area | What it affects |
|---|---|---|
| Hard starting, poor acceleration | L | Low-speed mixture |
| Chain moves at idle | T/LA (idle speed) | Idle RPM |
| Weak power at full throttle in the cut | H | High-speed mixture |
| Runs very hot at high speed | H | Engine temperature at WOT |
Why it matters
Correct L and H settings help your Craftsman 358350811 start easier, accelerate cleanly, and cut with steady power. They also help reduce overheating risk, which can shorten engine life.

Where is the model number on a chainsaw?
On the Craftsman gas chainsaw model 358350811, the model number is typically printed on the product identification label or tag on the saw body, often near the rear handle, starter housing, or fuel tank area. Use the model number to match the correct parts list and service instructions in the 358350811 operator's manual.
Where to look on the saw
Check these common label locations first (wipe off oil and sawdust so the print is readable):
- Near the rear handle or trigger area
- On or near the starter/recoil housing
- Around the fuel tank or oil tank area
- Under the top/cylinder cover (near the air filter cover)
- On the bottom of the chassis (underside of the saw)
Tips for finding a hard-to-read ID label
If the label is dirty, faded, or partially missing, these steps usually help:
- Clean the area with a dry rag first; avoid soaking labels with solvent
- Use a flashlight at an angle to make stamped or embossed text stand out
- Take a close-up photo and zoom in to read small print
- Check for a second tag or stamping on the crankcase or housing
Why the model number matters
The model number is what we use to match the correct bar, chain, fuel system parts, and engine components for your exact saw. For example, the 358350811 parts list includes items like the chainsaw bar, 18-in 180SDET041 and the chain 91PX062G, which must match the saw’s bar mount and chain specs.
Quick reference table
| What you’re trying to do | What to use | Example for this saw |
|---|---|---|
| Look up diagrams and parts | Model number | 358350811 |
| Match a specific replacement item | Part ID | 180SDET041 (bar), 91PX062G (chain) |
| Follow safety and operating steps | Manual | Operator’s manual for 358350811 |

Should I use 40 1 or 50 1 fuel for a chainsaw?
For the Craftsman 358350811 gas chainsaw, use a 40:1 gasoline-to-oil mix. That is 3.2 oz of synthetic 2-cycle air-cooled engine oil per 1 gallon of unleaded gasoline, as specified in the 358350811 owner’s manual.
Correct fuel mix for this model
Use fresh, clean unleaded gasoline and a quality synthetic 2-cycle oil designed for air-cooled engines.
- Mix at 40:1 every time
- Measure oil accurately; do not guess
- Mix fuel outdoors in an approved, marked container
- Wipe up spills before starting
- Move the saw at least 10 ft (3 m) from the fueling spot before starting
Quick mix table
| Mix ratio | Oil per 1 gallon gas | Notes |
|---|---|---|
| 40:1 | 3.2 oz | Correct ratio for Craftsman 358350811 |
| 50:1 | 2.6 oz | Too little oil for this model |
What happens if you run 50:1 in a saw designed for 40:1
A 50:1 mix reduces lubrication. On a 2-cycle engine built for 40:1, that increases friction and heat, which accelerates wear on internal parts like the piston and cylinder.
Related lubrication that matters just as much
This chainsaw also needs bar-and-chain oil; fuel mix lubricates the engine, not the cutting equipment.
- Fill the bar oil tank whenever you fill the fuel tank
- Low bar oil shows up as smoke at the chain or bar discoloration
- Use chainsaw bar oil when possible; SAE 30 oil works as a temporary substitute
Why it matters
Using the specified 40:1 mix helps the Craftsman 358350811 start easier, run cooler, and avoid premature engine wear while keeping performance consistent under load.
