Where is the model number on a chainsaw?
On the Craftsman chainsaw model 358740180, the model number is typically printed on the product identification label or ID tag on the saw body, often near the rear handle, starter housing, or under/near the cylinder cover. We use that number to match the correct parts list and the correct specifications in the 358740180 owner's manual.
Look for a sticker, metal tag, or stamped plate in these spots:
- Near the rear handle or throttle trigger area
- On or near the starter housing (recoil starter side)
- Under the cylinder cover (top cover area)
- Near the fuel mix fill cap or bar and chain oil fill cap
- Around the clutch cover side (bar mounting area)
If the label is dirty or faded, these steps usually make it readable:
- Wipe the area with a dry rag first; then use a small amount of mild cleaner
- Use a flashlight at an angle to highlight faint printing
- Take a close-up photo and zoom in
- Write down the full model number exactly as shown (all digits)
Craftsman chainsaws can look similar across model families, but parts like the chain, clutch, and bar hardware vary by model. Using the correct model number helps ensure you order compatible items such as the chainsaw chain 530051545 and avoid fitment issues.

What kind of gas goes in a Craftsman chainsaw?
For the Craftsman 358740180 gas chainsaw, use fresh unleaded gasoline mixed with 2-cycle engine oil at a 50:1 ratio. Do not use E15 or E85 blended fuels. Follow the fuel-handling and mixing directions in the 358740180 operator’s manual.
Use these basics every time you mix fuel:
- Unleaded gasoline (fresh, clean)
- 2-cycle engine oil made for air-cooled engines
- 50:1 mix ratio (gasoline:oil)
- Mix only what you will use soon; stale fuel causes hard starting and poor running
- Avoid contaminated fuel and dirty containers
| Gasoline amount | 2-cycle oil to add |
|---|---|
| 1 gallon | 2.6 fl oz |
| 1/2 gallon | 1.3 fl oz |
| 1 liter | 20 ml |
These fuel choices commonly cause starting and performance problems:
- E15 gasoline
- E85 gasoline
- Straight gas (no oil mixed in)
- Old fuel that has been sitting for weeks or months
- Fuel mixed in an unapproved or dirty container
We recommend these steps to reduce fire risk and prevent fuel system issues:
- Let the engine cool before refueling
- Mix and pour fuel outdoors, away from sparks or flames
- Wipe up spills before starting
- Move the saw at least 10 feet (3 meters) away from the fueling spot before starting
This model is a 2-cycle engine; the oil in the 50:1 mix lubricates internal engine parts. Using the wrong fuel (especially E15/E85, stale fuel, or the wrong oil ratio) leads to hard starting, rough running, and premature engine wear.

Is 40 1 or 50 1 better for chainsaws?
For the Craftsman 358740180 gas chainsaw, 50:1 is the correct and better mix because the operator’s manual specifies a 50:1 gasoline-to-2-cycle oil ratio. Using 40:1 adds extra oil, which can increase smoke and carbon buildup and may affect how the saw runs.
Follow the fuel guidance in the 358740180 operator’s manual. In day-to-day use, sticking with the specified ratio protects the engine and keeps performance consistent.
- Mix fresh, unleaded gasoline with 2-cycle engine oil at 50:1
- Measure carefully; don’t “eyeball” the oil
- Use fresh fuel (old fuel is a top cause of hard starting)
- Avoid higher-ethanol blends; the manual warns not to use E15 or E85
- If the saw smokes heavily or loads up at idle, re-check your mix and air filter condition
| Mix ratio | What it means | Typical result in a homeowner saw |
|---|---|---|
| 50:1 | Less oil in the fuel | Cleaner running, less carbon, matches the 358740180 spec |
| 40:1 | More oil in the fuel | More smoke, more deposits; can foul the spark plug over time |
Two-stroke engines rely on the fuel mix for lubrication. On the 358740180, the carburetor and engine are designed around 50:1, so the right ratio helps prevent plug fouling, excessive exhaust deposits, and inconsistent idle.
Use these checks before replacing parts:
- Confirm the mix is 50:1 and the gas is fresh
- Press the primer bulb as directed for starting
- Make sure the ON/STOP switch is set to ON
- Inspect and replace the spark plug if it’s fuel-soaked or carbon-fouled (see spark plug 585358205)
- If it still won’t start, follow the steps in tips for a hard to start chainsaw

What model number is a Craftsman 16 36cc chainsaw?
For Craftsman gas chainsaws in this family, the model number depends on the bar length: 358.740160 is the 16-inch version, and 358.740180 is the 18-inch version. For a “Craftsman 16 / 36cc” saw, the correct model number is typically 358.740160 (16-inch bar). See the 358740180 owner's manual for the model list and identification details.
Use the product ID label on the saw (not the bar or chain packaging). We recommend checking:
- The model number printed on the ID label (often on the housing or near the rear handle)
- The bar length listed for the model (16-inch vs 18-inch)
- The manual’s model list for your series
- Whether your saw uses the listed bar and chain combination for that model
| What you have | Typical match in this manual | What it means |
|---|---|---|
| 16-inch guide bar | 358.740160 | 16 in. bar configuration |
| 18-inch guide bar | 358.740180 | 18 in. bar configuration |
The model number controls the correct parts lookup and safety-approved cutting setup (guide bar and chain). Ordering by “16-inch” or “36cc” alone can lead to the wrong chain, clutch cover, or oiling components.
If you are replacing wear items, match parts to your exact model; for example, the Craftsman 358740180 parts list includes items like the chainsaw chain 530051545 and the chainsaw chain brake assembly 530071893.

Where is the fuel filter in a Craftsman chainsaw?
On the Craftsman 358740180 gas chainsaw, the fuel filter sits inside the fuel tank, attached to the end of the fuel line. You access it by removing the fuel cap and gently pulling the fuel line and filter up through the tank opening (then reinstall it the same way). Refer to the 358740180 owner's manual for the maintenance schedule and fuel-handling safety.
- Turn the engine OFF and let it cool completely.
- Move to a well-ventilated outdoor area away from sparks or flames.
- Remove the fuel cap.
- Use a clean bent wire hook or long needle-nose pliers to grab the fuel line inside the tank.
- Pull the fuel line up just far enough to reach the filter.
- Twist and pull the filter off the fuel line; press the new filter on firmly.
- Tuck the line and filter back into the tank so the filter can move freely.
- Cracked, stiff, or swollen fuel line (a common cause of hard starting).
- Dirt or water in the fuel.
- A filter that looks dark, gummy, or restricted.
| What you notice | Often points to | What to do next |
|---|---|---|
| Won’t start or only starts on choke | Restricted fuel filter or air leak in fuel line | Replace filter; inspect fuel line |
| Starts, then dies when you throttle up | Fuel starvation | Replace filter; check fuel mix and fresh fuel |
| Runs rough at all speeds | Fuel delivery or carburetor issue | Check filter/lines first, then carburetor |
A clogged in-tank fuel filter limits fuel flow, which can cause hard starting, stalling, and rough running. The manual’s maintenance chart calls for replacing the fuel filter on a yearly interval, and it also emphasizes safe fuel handling practices.

Who makes Craftsman chainsaws now?
Craftsman chainsaws are built by different manufacturers depending on the specific model and production era. For the Craftsman 358740180 gas chainsaw, the best way to confirm the exact manufacturer and specifications is to match the model and bar length details shown in the 358740180 owner's manual.
Craftsman is a brand; it is common for the brand owner to source chainsaws from more than one manufacturer over time. That is why two Craftsman saws can share some parts and service procedures but still differ in engine design, carburetor setup, or bar and chain specs.
Use these quick checks on your Craftsman 358740180:
- Confirm the model number on the data label matches 358740180 exactly.
- Verify the bar length; the manual lists 358.740180 as an 18-inch bar model.
- Compare the illustrated parts breakdown and maintenance section to your saw’s layout.
- Use the “Parts & Ordering” and support information in the manual to align your unit to the correct parts list.
- When ordering, match by model number first, then by the exact part ID.
Even when manufacturers change, parts ordering should be driven by the model number and the exact part ID used on that design.
| What you’re matching | Best match method | Example from this model’s parts list |
|---|---|---|
| Wear items | Match by model number and part ID | Chainsaw chain 530051545 |
| Drive system parts | Match by model number and part ID | Chainsaw clutch 530057907 |
| Safety and control parts | Match by model number and part ID | Chain brake, switch components (varies by design) |
Knowing the correct manufacturer is less important than matching the correct model number (358740180) and the correct part ID. That prevents ordering a chain, clutch, or oiling component that looks similar but does not fit or operate safely.
