How to look up chainsaw serial number?
For your Craftsman chainsaw model 358353691, we typically find the serial number stamped or printed on the engine housing or crankcase area, often near the muffler. Once you have it, we use that serial number to confirm production details and help match the correct replacement parts.
Check these common locations on the saw body (wipe off oil and sawdust first):
- Flat spot on the crankcase or engine/motor housing
- Near the muffler (left or right side when viewing from the top)
- On a sticker/label on the rear handle area or near the fuel tank
- Along the starter housing (recoil starter side)
- Under the top cover (near the air filter area)
For parts ordering, the most important identifier is usually the model number (358353691), then we use the serial number to narrow variations when needed.
- Start with the model-based parts list for 358353691
- If a diagram shows multiple versions, use the serial number to pick the correct version
- If you are replacing fuel system parts, match what is physically on your saw (line routing, fitting style, etc.)
If you are chasing a fuel leak or hard-start issue while you are checking the serial tag, common wear items include the fuel line 530069216 and the fitting 530023877.
| What to check | What it tells us | Why it helps |
|---|---|---|
| Serial number is readable | Confirms the unit identity | Avoids ordering the wrong version |
| Model number matches 358353691 | Confirms the correct parts breakdown | Ensures diagrams and parts fit |
| Label is missing/damaged | Use physical part matching | Still lets you repair the saw |
Chainsaws can have small production changes (fuel line routing, fittings, bar/chain setups). Having the serial number handy helps us narrow those differences so you get the right Craftsman chainsaw parts the first time.

Where is the model number on a chainsaw?
On a Craftsman chainsaw like model 358353691, the model number is usually printed on a sticker or stamped on a small metal plate on the saw body. The most common spots are near the rear handle, starter housing, or the area by the bar mount.
Look for a paper label, foil sticker, or metal tag in these areas:
- On the rear handle or the handle frame near the trigger
- On the starter/recoil housing (the side you pull to start)
- Near the bar mount/clutch cover area (where the guide bar bolts on)
- On the underside of the saw body near the fuel tank
- Along the side of the chassis near the muffler (label may be heat-darkened)
Model tags on gas chainsaws get oily and scratched, so a quick cleanup helps.
- Wipe the area with a rag and a small amount of degreaser
- Use a flashlight at a low angle to read faint stamping
- Take a phone photo and zoom in to confirm each digit
- Write down the full model number exactly as shown (for example, 358353691)
Using the correct model number ensures the parts list matches your exact bar/chain setup and fuel system.
| What you’re replacing | What the model number helps confirm | Example part on this model page |
|---|---|---|
| Bar and chain | Bar length and chain spec compatibility | Chain 91PX056G |
| Fuel system | Correct routing and connection style | Fuel line 530069216 |
| Clutch/drive parts | Sprocket style and fit | Drum sprocket 530069166 |
Chainsaws often have multiple versions that look similar. Using the exact model number prevents ordering a bar, chain, or fuel line that does not fit your Craftsman saw.

Is 40 1 or 50 1 better for chainsaws?
For the Craftsman 358353691 gas chainsaw, the “better” mix is the ratio the engine is designed for: 50:1 is the modern standard for many 2-cycle chainsaws, while 40:1 provides more oil and can be useful for older designs or hard use. Using too little oil (leaner than required) causes rapid engine wear.
A 2-stroke engine relies on oil mixed into the gasoline to lubricate the piston, rings, crank bearings, and cylinder.
- 50:1 = less oil in the fuel (cleaner running, less smoke, fewer deposits)
- 40:1 = more oil in the fuel (more lubrication, but can increase carbon buildup)
- Too lean on oil (example: running 50:1 in an engine that needs 40:1) risks scoring the cylinder and piston
- Too rich on oil (example: running 40:1 in an engine tuned for 50:1) can foul the spark plug and clog the muffler screen
Because no model-specific fuel-mix documentation is provided here for 358353691, we use standard 2-cycle best practices.
- If your saw’s decal or prior owner instructions specify 50:1, stick with 50:1
- If it specifies 40:1, do not dilute to 50:1
- Use fresh, ethanol-free fuel when possible; stale fuel causes hard starting and poor idle
- Measure oil accurately; “eyeballing” the mix is a common cause of failures
- If the saw smokes heavily or loads up at idle, check the muffler spark arrestor screen and plug condition
| Gasoline amount | 50:1 oil | 40:1 oil |
|---|---|---|
| 1 gallon | 2.6 oz | 3.2 oz |
| 2 gallons | 5.1 oz | 6.4 oz |
| 5 gallons | 12.8 oz | 16.0 oz |
These issues often show up when the fuel system is aging or partially restricted:
- Replace cracked or soft fuel hose such as the fuel line 530069216
- Inspect the tank connection and grommet area, including the fitting 530023877
- If it bogs at high speed, clean the muffler outlet and consider replacing the screen 530035178
The correct oil ratio protects the engine while keeping combustion clean. A slightly oil-richer mix can be forgiving, but an oil-lean mix can ruin a 2-cycle top end quickly.
