How to look up chainsaw serial number?
On the Craftsman chainsaw model 358350280, the serial number is typically stamped or printed on the engine area, most often on the motor housing or crankcase near the muffler. Once you find it, record it exactly as shown (letters, numbers, and any dashes).
Where to check on the saw
Look for a flat, easy-to-stamp surface on the powerhead:
- On the motor housing or crankcase
- To the left or right of the muffler when viewing from the top
- Near the starter/recoil housing area
- On a label plate or sticker on the body (if your unit uses a decal)
- Under heavy grime; wipe the area clean to reveal stamped characters
Quick steps to find it (fastest method)
- Turn the engine off and let it cool completely.
- Remove the top cover if needed to improve visibility.
- Wipe the area around the muffler and crankcase with a rag.
- Use a flashlight at a low angle; stamped numbers show up better with side lighting.
- Write the serial number down and take a clear photo for your records.
Serial number vs. model number (what you actually need)
| Item | What it identifies | Example format | When it matters |
|---|---|---|---|
| Model number | The product design family | 358350280 | Picking diagrams and matching parts |
| Serial number | Your specific production unit | Varies | Confirming production run details and service history |
Why it matters
We use the model number to match parts like a fuel line, oil pump, or ignition coil, but the serial number helps narrow down production variations when a manufacturer changed a component mid-run.
For model-specific labeling locations and diagrams, use the 358350280 owner's manual.

Where is the model number on a chainsaw?
On the Craftsman chainsaw model 358350280, the model number is typically printed on the saw’s identification label or ID tag on the housing. Common spots include the rear handle area, the starter (recoil) side cover, or near the oil and fuel tank area; check the 358350280 owner’s manual for the exact label location and examples.
Where to look first
- Rear handle or trigger handle area (outside of the housing)
- Recoil starter cover (pull-cord side)
- Bottom of the saw body near the bar studs
- Near the fuel cap or oil cap area
- Under the top cover (air filter cover area)
What the label can look like
Most gas chainsaws use a small sticker or metal/plastic ID tag. It may include:
- Model number (for example, 358350280)
- Serial number
- Engine displacement or other specs
- Safety markings
| What you see | What it means | What to do |
|---|---|---|
| “358.350280” or “358350280” | Model number formatting can vary | Write it down exactly as shown |
| Serial number only | Model may be on a different line or nearby label | Check adjacent text and other sides of the housing |
| Label is worn or missing | Normal on older saws | Use the manual’s diagrams and compare to parts listings |
If the label is damaged or missing
- Clean the area with a damp rag first; oil and sawdust can hide the print
- Check under removable covers (top cover, clutch cover)
- Compare your saw’s assemblies (bar, clutch cover, fuel system) to the diagrams in the 358350280 owner’s manual
Why it matters
The model number ensures we match the correct Craftsman parts and diagrams for your chainsaw, especially for fit-critical items like a fuel line, carburetor parts, or an oil pump.

Should I use 40 1 or 50 1 fuel for a chainsaw?
For the Craftsman 358350280 gas chainsaw, we recommend using the fuel-to-oil ratio specified in the 358350280 owner's manual. In general, 50:1 is common for many newer 2-cycle engines using quality 2-cycle oil, while 40:1 adds more oil for extra lubrication but can increase smoke and carbon buildup.
Quick ratio comparison
| Mix ratio | Oil per 1 gallon gas | What you may notice |
|---|---|---|
| 50:1 | 2.6 oz | Cleaner running, less smoke |
| 40:1 | 3.2 oz | More lubrication, more smoke and deposits |
What we recommend for best results
- Follow the ratio listed for Craftsman 358350280 in the 358350280 owner's manual.
- Use fresh, ethanol-free gas when possible; stale fuel is a top cause of hard starting.
- Use a high-quality 2-cycle oil intended for air-cooled engines.
- Mix in an approved fuel can; shake before filling the tank.
- Only mix what you will use in 30 days (or follow the oil maker’s storage guidance).
If the saw runs poorly after changing mix ratio
A mix that is too lean on oil can increase wear; a mix that is too heavy on oil can foul the spark plug and load up the muffler screen.
Check these common fuel-related issues:
- Cracked or hardened fuel line (consider ayp lawn & garden equipment fuel line, large 530069216)
- Air leaks at carburetor mounting surfaces (consider Craftsman lawn and garden equipment carburetor gasket 530019249)
- Carburetor metering issues (consider ayp lawn & garden equipment engine carburetor rebuild kit 530069826)
Why it matters
The correct 2-cycle mix ratio protects the piston and cylinder, keeps the carburetor tuned correctly, and helps your chainsaw start easier and run at the right temperature under load.
