Craftsman 358350180 gas chainsaw Parts

For the Craftsman 358350180 gas chainsaw, we use a 40:1 fuel mix. That ratio is 3.2 oz of 2-cycle air-cooled engine oil per 1 gallon of unleaded gasoline, which provides the lubrication this engine is designed to run on (using 50:1 can reduce lubrication).

Correct fuel mix for model 358350180

Use these quick mix amounts:

• 1 gallon gas: 3.2 oz 2-cycle oil (40:1)
• 2 gallons gas: 6.4 oz 2-cycle oil
• 5 gallons gas: 16 oz (1 pint) 2-cycle oil
• Use 2-cycle air-cooled engine oil (not automotive oil, not marine/boat oil)
• Mix in an approved fuel container; add oil, then gasoline, then shake to blend

Mix ratio	Oil per 1 gallon gas	When to use it
40:1	3.2 oz	Correct ratio for Craftsman 358350180
50:1	2.6 oz	Used on some other engines; not the target ratio here

Fuel handling and storage tips

Old fuel is one of the most common reasons a gas chainsaw runs poorly. We follow these practices:

• Use fresh unleaded gasoline and only mix what you will use soon
• Avoid alcohol-blended fuels for long storage; they can attract moisture
• If storing 30 days or longer, drain the tank and run the engine until the fuel system is empty
• A fuel stabilizer helps reduce gum deposits during storage
• At the start of the next season, use fresh fuel mixed at the proper ratio

Why it matters

The oil in the mix lubricates the piston, cylinder, and crank bearings. Running lean on oil (such as 50:1 when the saw calls for 40:1) increases wear and can shorten engine life.

The Craftsman 358350180 is a 42cc (2.6 cu. in.) 2-cycle gasoline chainsaw that uses an 18-inch guide bar and chain. It ships fully assembled and is designed for general cutting tasks; we recommend following the safety, fueling, and operating steps in the 358350180 operator's manual.

Key features and what they mean

• 42cc 2-cycle engine: strong power-to-weight for typical homeowner cutting
• 18-inch bar and chain: good reach for limbing and cutting medium logs
• Factory-adjusted carburetor: normal to notice a fuel smell or light residue when new
• No assembly required: the saw is listed as fully assembled out of the carton
• Included items (varies by package): bar tool, gloves, gas can, bar and chain lube, 2-cycle oil; model 358350180 also lists a chain and carrying case

What’s included (quick reference)

Item	Purpose	Notes
18-inch bar and chain	Cutting system	Bar and chain are wear items
2-cycle oil	Fuel mix	Manual references a 40:1 mix
Bar and chain lube	Chain lubrication	Helps reduce bar and chain wear
Bar tool	Adjustments	Used for bar nuts and chain tensioning

Why it matters

Matching the correct model number (358350180) to the correct bar length, chain type, and fuel mix prevents hard starting, poor cutting performance, and premature wear on parts like the clutch and oiling system.

Common parts customers replace on this model

If you are maintaining or repairing the saw, these model-matched parts are commonly needed:

• Chainsaw bar, 18-in 180SDET041 (guide bar replacement)
• Chain 91PX062G (cutting chain replacement)
• Ayp lawn & garden equipment fuel line, large 530069216 (fuel delivery issues)
• Primer bulb 530071835 (starting and priming issues)
• Chainsaw oil pump 530071259 (chain not oiling)

On the Craftsman 358350180 gas chainsaw, L and H are the carburetor mixture adjustment screws: L controls the low-speed (idle and acceleration) fuel mixture, and H controls the high-speed (wide-open throttle) fuel mixture. These settings affect starting, throttle response, and cutting power.

What each screw does

• L (low-speed mixture): Fine-tunes how the engine runs at idle and when you squeeze the trigger.
• H (high-speed mixture): Fine-tunes fuel delivery at full throttle under load.
• Idle speed screw (often marked T, S, or I): Sets idle RPM; it does not change the fuel mixture.

Quick symptoms guide

What you notice	Most likely adjustment area	What it usually means
Dies or bogs when you hit the throttle	L	Low-speed mixture is off
Races at idle or chain creeps	Idle speed screw (T/S/I)	Idle set too high (or clutch issue)
Lacks power in the cut, runs hot	H	High-speed mixture too lean
Smokes heavily, won’t clean out at full throttle	H	High-speed mixture too rich

Safe, practical adjustment tips

• Start with the saw warmed up and the chain brake engaged.
• Adjust in small increments (about 1/8 turn at a time).
• Set idle speed so the engine idles smoothly without the chain moving.
• If the saw only runs with the choke partly on, the carburetor is typically running lean from a fuel delivery issue (old fuel, air leak, clogged passages).
• For the correct adjustment procedure and baseline settings, follow the carburetor adjustment section in the 358350180 operator’s manual.

Why it matters

Correct L and H settings keep the 2-cycle engine properly lubricated by the fuel-oil mix. A mixture that is too lean can cause overheating and poor performance; too rich can foul the spark plug and waste fuel.

On your Craftsman gas chainsaw model 358350180, the model number is on an ID label attached to the saw body. Most often it is on the side of the engine housing, near the rear handle, or on the underside near the fuel and oil tanks. Confirm the exact digits in the 358350180 operator’s manual.

Common places to check on the saw

Look for a sticker or metal tag in these areas:

• Side of the engine housing (near the starter/recoil cover)
• Rear handle area (near the trigger or handle mount)
• Underside of the saw body (near the fuel tank and bar oil tank)
• Near the bar mount and clutch cover area (around the mounting studs)
• Muffler side of the chassis (labels can be heat-darkened)

What to write down so parts match

Copy the identification exactly as it appears on the label:

• Model number: 358350180 (write every digit in order)
• Any extra numbers or letters on the same label (often a type or production code)
• Brand name: Craftsman

Quick tips if the label is dirty or worn

• Wipe with a dry rag first, then use mild cleaner on a cloth
• Shine a flashlight across the label at a low angle to make faint print stand out
• Take a close-up photo and zoom in to read worn characters

Why it matters

We use the exact model number to match the correct illustrated parts list and compatible items such as the chain, guide bar, fuel system parts, and ignition components. One wrong digit can pull parts for a different saw.

What you find on the label	What it means
358350180	Correct model for this parts list
A different 358xxxxxx number	Parts can vary; use the exact number shown
