Should I use 40 1 or 50 1 fuel for a chainsaw?
For a Craftsman 358354810 gas chainsaw, the correct mix is the ratio the engine was designed for; most modern 2-cycle chainsaws run 50:1, while some older designs specify 40:1. Using too little oil (leaner mix than required) is what causes damage, so match the spec and keep the fuel fresh.
- If your saw is specified for 50:1, you can typically run 40:1 without harming the engine (it is oil-richer), but it may smoke more and can foul the spark plug over time.
- If your saw is specified for 40:1, do not run 50:1; that is less oil and can accelerate piston and cylinder wear.
- If you are unsure, start by checking any label on the fuel cap, starter housing, or air filter cover; then use the parts diagrams to confirm you are working with the correct model (Craftsman 358354810).
| Gasoline amount | 50:1 oil | 40:1 oil |
|---|---|---|
| 1 gallon | 2.6 oz | 3.2 oz |
| 2 gallons | 5.1 oz | 6.4 oz |
| 1 liter | 20 ml | 25 ml |
- Use fresh, ethanol-free fuel when possible; avoid old gas that has been sitting for weeks.
- Use a quality 2-cycle oil intended for air-cooled engines.
- Mix in an approved container; add oil first, then gas, then shake.
- If the saw starts but dies or surges, inspect the fuel system for cracks or air leaks; a split fuel line can mimic a “wrong mix” problem.
- Replace worn fuel delivery parts when needed, such as the fuel line 530069216.
The oil in the mix is the engine’s lubrication. A richer mix (40:1) increases lubrication but can increase deposits; a leaner mix (50:1) burns cleaner but only works safely when the engine is designed for it.

What company makes Craftsman chainsaws?
Craftsman chainsaws are built by different manufacturers depending on the model and production era. For Craftsman model 358354810, the parts and model format align with the Poulan/Weed Eater family of chainsaws (an AYP-built design), which is why many replacement parts cross over with those platforms.
Even when the Craftsman name is on the cover, the OEM design determines which fuel system, bar adjuster, and hardware parts fit.
- Use the full model number 358354810 when shopping parts
- Match parts by diagram and part ID, not by “looks like”
- Replace fuel lines and small hardware with the exact listed items to avoid air leaks and poor running
- Keep bar adjuster parts matched as a set so chain tensioning works correctly
These common items are model-matched and are good examples of why ordering by model matters:
- Fuel line 530069216 (fuel delivery line)
- Adjustment bar 530015385 (bar adjuster screw)
- Pin 530023064 (bar adjuster pin)
- Bar 160PXDD176 (guide bar)
| Term | What it means | Why you care |
|---|---|---|
| Craftsman | The retail brand name | Branding does not guarantee shared parts across models |
| OEM (Poulan/Weed Eater family) | The underlying saw design and parts system | Determines the correct carburetor, fuel line, and bar adjuster parts |
| Model number 358354810 | Your exact configuration | The fastest way to get the right replacement parts |
Chainsaws are sensitive to small differences in fuel line routing, bar adjuster geometry, and mounting patterns. Using the correct model-based parts prevents hard starting, lean running, and chain tension problems.

Where is the model number on a chainsaw?
On a Craftsman gas chainsaw like model 358354810, the model number is usually printed on a sticker or stamped on a metal tag on the saw body. Check areas that stay relatively clean and flat, such as the rear handle, starter housing, or near the bar mount.
Look for a paper label, foil sticker, or metal plate in these spots:
- Rear handle area (near the trigger or grip)
- Starter/recoil housing (the side you pull to start)
- Bar mount/clutch cover area (near where the guide bar bolts on)
- Bottom of the saw body (underside of the crankcase)
- Near the fuel tank or oil tank caps
Most chainsaw ID tags include a few fields. Here is what you might see:
| Tag field | What it means | Example you are looking for |
|---|---|---|
| Model number | Identifies the exact saw version for parts | 358354810 |
| Serial number | Unique ID for your specific unit | Varies |
| Engine info | Displacement or emissions family | Varies |
- Wipe the area with a dry rag first; oil and sawdust can hide the print.
- Use a flashlight at an angle; stamped numbers show up better with side lighting.
- If the sticker is damaged, check the opposite side of the housing and the underside.
We use the model number to match the correct Craftsman chainsaw parts and diagrams. Even small model-number differences can change fit for items like a fuel line, bar adjuster parts, or fasteners.
If you are confirming parts for this model, start with a common match like the fuel line 530069216.
