Craftsman 316380190 gas chainsaw Parts

On the Craftsman gas chainsaw model 316380190, the model number is printed on the product identification label attached to the saw body. Check the engine/motor housing area first, then inspect other flat surfaces on the chassis where a label can be read without removing major parts.

Where to look on a Craftsman 316380190 chainsaw

Check these common label locations (in this order):

• Side of the engine/motor casing (most common)
• Rear of the saw body near the handle area
• Bottom/underside of the saw body (near the crankcase area)
• Near the starter housing or recoil cover area
• Under the air filter cover (only if it lifts off without tools)

For diagrams and model identification details, use the 316380190 operator's manual.

How to record the model number correctly

Write the model number exactly as shown on the label so parts match the correct version.

• Copy every digit in order (example format in the manual: 316.380190)
• Include any extra letters or suffixes if your label shows them
• Take a clear photo before the label gets dirty or scratched
• Clean the label gently with a dry rag if it is oily or dusty

Quick check: model number vs. part numbers

What you are reading	Example	What it is used for
Model number	316380190 (may appear as 316.380190)	Identifies the exact chainsaw for parts lookup
Part number	753-08107	Identifies a specific replacement part

Why it matters

We use the model number to match the correct Craftsman parts diagrams and ensure items like the guide bar, saw chain, carburetor, and ignition parts fit your exact 316380190 configuration.

For the Craftsman 316380190 gas chainsaw, 40:1 is the better choice because it is the manufacturer-specified fuel/oil ratio. Using 50:1 in this model reduces lubrication and can increase wear; stick with 40:1 unless the 316380190 operator’s manual specifies otherwise for a special condition.

What to use for model 316380190

The manual lists a 40:1 fuel/oil ratio for this 2-cycle chainsaw. That means:

• Use fresh, unleaded gasoline (typical 87 octane or higher)
• Use 2-cycle engine oil intended for air-cooled 2-stroke engines
• Mix in an approved fuel container; do not mix in the saw’s tank
• Shake the container before each refuel to re-blend the oil
• Make only what you will use soon; old fuel causes hard starting and poor running

40:1 vs 50:1 at a glance

Mix ratio	Oil per 1 gallon gas	What it generally does
40:1	3.2 fl oz	More lubrication; best match for this Craftsman model
50:1	2.6 fl oz	Less oil; can run cleaner, but risks under-lubrication if not specified

Common symptoms of the wrong mix

If the mix is off, you can see performance issues quickly. Watch for:

• Hard starting or stalling at idle
• Loss of power under load
• Excessive smoke and oily residue (too much oil)
• Overheating, “dry” sound, or scoring risk (too little oil)
• Spark plug fouling; consider replacing with the correct plug such as spark plug 753-08107 if it becomes contaminated

Why it matters

A 2-cycle engine depends on the fuel mix for lubrication. On the 316380190, the correct 40:1 ratio protects the piston, cylinder, and crank bearings while keeping the saw reliable during cutting.

For the Craftsman gas chainsaw covered here, the model number is 316.380190 (also shown as 316380190). If your saw is described as “16-inch, 36cc,” verify the exact model on the data label because that description can refer to a different Craftsman chainsaw.

How to confirm the model number on your saw

Use the model/serial label on the chainsaw body, then match it to the parts diagrams.

• Look on the housing near the rear handle, starter cover, or fuel tank area
• Wipe off oil and sawdust so the label is readable
• Copy the model number exactly as printed (including any dots)
• Record the serial number as well; it helps with parts identification
• Compare your model number to the parts list before ordering a bar, chain, or carburetor

What the model number looks like for this chainsaw

The same model can appear with or without punctuation.

Label format you may see	Same model?
316.380190	Yes
316380190	Yes

For model-specific specifications and identification details, use the 316380190 operator’s manual.

Why it matters

The model number controls parts fit and cutting-system compatibility (guide bar length, chain type, and mounting pattern). Using the correct model number prevents ordering the wrong bar, chain, air filter, or ignition parts.
