Where is the model number on a chainsaw?
On the Craftsman gas chainsaw model 358350830, the model number is typically found on the product identification label or tag on the saw body (often near the rear handle, starter housing, or fuel tank area). Our operator documentation also lists it as Model No. 358.350830 in the 358350830 operator's manual.
Where to look on the saw
Check these common spots first; they are the most likely locations for the ID label/tag:
- Near the rear handle or trigger handle area
- On or near the starter (recoil) housing
- Around the fuel tank or oil tank area
- On the chassis/frame area where the handle mounts
- Near the bar mount side cover area (with the bar and chain)
What the model number looks like
For this Craftsman chainsaw, you may see the model formatted in more than one way.
| How it may appear | What it means |
|---|---|
| 358350830 | Model number without punctuation |
| 358.350830 | Same model number with a dot (common in manuals) |
Tips if the label is dirty or hard to read
- Wipe the label gently with a damp cloth; avoid harsh solvents that can remove printing.
- Use a flashlight at an angle to make faint text easier to see.
- Take a close-up photo and zoom in; this often reveals worn characters.
- Match the bar length and general configuration to the manual cover page for confirmation.
Why it matters
The model number is the fastest way to match the correct parts and diagrams for your chainsaw, especially for wear items like the fuel line, air filter, and chain components.

Should I use 40 1 or 50 1 fuel for a chainsaw?
For the Craftsman 358350830 gas chainsaw, we use a 40:1 fuel mix: 3.2 oz of synthetic 2-cycle air-cooled engine oil per 1 gallon of unleaded gasoline. That ratio is the correct lubrication target for this engine and helps prevent premature wear.
Correct fuel mix for model 358350830
Use this exact mix ratio every time you refuel:
- Mix 40:1 (gasoline:oil)
- Add 3.2 oz oil to 1 gallon of unleaded gasoline
- Use synthetic 2-cycle air-cooled engine oil (not automotive or marine oil)
- Shake the fuel can briefly after mixing so the oil disperses evenly
- Use fresh fuel; for seasonal storage, drain the tank and run the engine until the fuel system is empty
For the full fueling and safety steps, follow the 358350830 owner's manual.
40:1 vs 50:1 at a glance
| Mix ratio | Oil per 1 gallon gas | What it means |
|---|---|---|
| 40:1 | 3.2 oz | More lubrication; correct spec for this model |
| 50:1 | 2.6 oz | Less lubrication; can increase wear risk if the engine is designed for 40:1 |
Why it matters
Two-cycle engines rely on the oil in the fuel for crankshaft, piston, and cylinder lubrication. Running lean on oil (such as 50:1 when the saw calls for 40:1) increases friction and heat, which shortens engine life.
If the saw is hard to start or runs poorly after fueling
Fuel ratio is only one piece of the puzzle. These checks solve most starting and running issues:
- Replace old fuel with a fresh 40:1 mix
- Check for cracked or loose fuel lines; replace with the correct ayp lawn & garden equipment fuel line, large 530069216 if needed
- Make sure the fuel tank cap seals properly
- Clean or replace the air filter
- If fuel delivery is inconsistent, inspect the carburetor and fuel line fitting

How to look up chainsaw serial number?
On the Craftsman chainsaw model 358350830, the serial number is typically stamped into the engine area (motor housing or crankcase) on a flat spot near the muffler. We use that serial number to match the correct parts list and manual information for your exact saw.
Where to check on the saw
Look for a stamped or printed ID on a flat surface around the engine:
- On the motor housing or crankcase
- To the left or right of the muffler when looking down from the top
- Near the recoil starter area (same general engine housing zone)
- On a label plate if your saw has one (wipe off oil and sawdust first)
If the stamping is hard to read, clean the area with a dry rag and use a flashlight at an angle to make the numbers stand out.
How to use the serial number (and why it matters)
The serial number helps confirm the exact production version of your 358350830. That matters because small changes can affect fit for items like the fuel system, ignition parts, and cutting hardware.
| What you’re looking for | What it’s used for |
|---|---|
| Model number (358350830) | Identifies the base parts diagram and manual |
| Serial number | Narrows down the exact build/version |
| Bar and chain info decal | Confirms the correct replacement bar and chain setup |
Tips if you can’t find it right away
- Check with the bar and chain removed (engine area is easier to see)
- Avoid scraping with metal tools; use a rag or soft brush
- Write the number down exactly as shown (include any letters)
- Use the 358350830 owner's manual to confirm ID locations and general saw identification details
Related parts you may match using the serial number
Once you have the serial number, we can help you match common wear items for this model, such as:
- Fuel tank cap 580940901
- Air filter, fuel line, carburetor, and ignition components
Why it matters
Using the correct serial number prevents ordering a part that looks similar but does not fit, especially for fuel line routing, carburetor connections, and ignition wiring.
