Craftsman 358350821 chainsaw Parts

On the Craftsman 358350821 gas chainsaw, the serial number is typically stamped or printed on the engine/motor housing or crankcase area, usually on a flat spot near the muffler. We use that serial number to match the correct parts list and manual information.

Look for a stamped metal tag, a printed label, or a stamped number on a flat surface in these common locations:

• On the engine housing or crankcase near the muffler (left or right side when viewing from the top)
• Near the starter/recoil housing area
• On the rear handle area or chassis/frame label (if your unit uses a combined model/serial label)
• On the underside of the saw body where debris does not rub it off as easily

If the saw is dirty, wipe the area first; oil and sawdust can hide stamped numbers.

Once you find it, use the serial number along with the model number (358350821) to confirm you are selecting the right diagrams and replacement parts.

• Write the serial number exactly as shown (include letters, dashes, and leading zeros)
• Take a clear photo before cleaning aggressively (stamps can be faint)
• Keep the serial number with your maintenance notes (chain, bar, spark plug, fuel line service)

Chainsaws can have small production changes over time (fuel system routing, ignition parts, starter components). Using the serial number helps ensure you get the right replacement part the first time.

For additional identification and operating details, use the 358350821 owner's manual.

For the Craftsman chainsaw model 358350821, we use a 40:1 fuel mix: 3.2 oz of quality synthetic 2-cycle air-cooled engine oil per 1 gallon of unleaded gasoline. That ratio is the correct choice for this model and helps protect the engine under load; see the owner's manual.

Use this exact ratio every time you mix fuel:

• Unleaded gasoline (fresh)
• Synthetic 2-cycle air-cooled engine oil
• Mix at 40:1 (oil:gas)
• Shake the fuel container after mixing so the oil is fully blended
• Do not use automotive oil or marine (boat) oil

A 50:1 mix contains less oil than 40:1. On a chainsaw designed for 40:1, that reduced lubrication can increase wear in the piston, rings, and cylinder, especially during hot cutting conditions or long run times.

Fuel mix is only half the lubrication story. The guide bar and chain also need oil continuously.

• Fill the bar oil tank whenever you fill the fuel tank
• Use chainsaw bar oil when possible (SAE 30 is a workable substitute)
• If you see smoke at the chain or bar discoloration, stop and check bar-and-chain oiling

If you will store the chainsaw for 30 days or longer, we drain the fuel system and run the engine until the fuel lines and carburetor are empty. Fresh fuel next season prevents hard-start and rough-running problems.

On the Craftsman chainsaw model 358350821, the model number is typically printed on the product identification label or stamped on an ID tag on the saw body. Use the label first; if it is worn or missing, check the ID tag area on the housing.

Check these common locations on a gas chainsaw like the 358350821:

• On the rear handle area near the trigger
• On the starter housing (recoil starter side)
• Near the fuel tank or oil tank area
• On the bottom of the saw body (underside of the crankcase)
• On a decal near the bar mount or clutch cover area

If you have the documentation handy, the model is also shown on the cover of the 358350821 operator's manual.

Use this checklist so you capture the right information when ordering parts like a chain, guide bar, or fuel system components:

• Model number (example: 358350821)
• Bar length (this model is commonly paired with an 18-inch bar)
• Serial number (if present)
• Any engine size markings (often shown as cc)

We use the model number to match the correct parts diagrams and ensure fit. Even small differences between similar Craftsman chainsaws can change the correct chain, bar plate, clutch, or fuel line routing.
