Craftsman 358350990 chainsaw Parts

For the Craftsman 358350990 gas chainsaw, the “better” mix is the one the manufacturer specifies; in general, 50:1 is standard for many newer 2-cycle engines, while 40:1 adds more oil for extra lubrication but can increase smoke and carbon buildup. Confirm the exact ratio in the 358350990 owner's manual.

• Use the ratio listed for model 358350990 in the 358350990 owner's manual.
• Use fresh, ethanol-free fuel when possible; stale fuel causes hard starting and rough running.
• Measure oil accurately; “a little extra” oil can foul the spark plug and clog the spark arrestor screen.
• Mix in an approved 2-cycle oil designed for air-cooled engines.
• If the saw starts hard or runs unevenly after changing mix ratio, troubleshoot fuel delivery and carburetion (not just the ratio).

The fuel-oil ratio controls lubrication and combustion. Too little oil accelerates piston and cylinder wear; too much oil increases carbon buildup that can restrict the muffler and spark arrestor, reducing power and making the saw run poorly.

If you’re chasing a “won’t start” or “runs rough” issue, the most common causes are fuel quality, clogged fuel lines, and carburetor problems. These guides help narrow it down:

On the Craftsman chainsaw model 358350990, 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 top cover). We use that model number to match the correct parts list and diagrams.

Check these common label locations first:

• On the rear handle area near the trigger
• On the starter (recoil) housing side
• Near the bar mount area (clutch cover side)
• Under the top cover (air filter/carburetor access area)
• On the underside of the saw body near the fuel or oil tank area

If the label is dirty, wipe it with a rag and mild cleaner so the numbers are readable.

Most chainsaw ID labels include more than just the model number. You may see:

• Model number (for this saw: 358350990)
• Serial number
• Engine displacement or power rating
• Emissions or compliance information

Using the exact model number prevents ordering the wrong items, especially for fit-sensitive parts like a fuel line, carburetor, or chain brake components.

For model-specific identification details and diagrams, use the 358350990 owner’s manual.
