Craftsman 358341900 chainsaw Parts

For the Craftsman 358341900 gas chainsaw, we follow the fuel mix ratio specified in the 358341900 owner's manual. In general, most modern 2-cycle chainsaws are designed for 50:1 (gasoline:2-cycle oil); 40:1 is sometimes used on older or heavily worked saws when the manufacturer allows it.

• Use the ratio listed for your exact model and engine.
• Mix with fresh, ethanol-free fuel when possible and a high-quality 2-cycle oil rated for air-cooled engines.
• If you are unsure what is currently in the tank, drain and remix to the correct ratio before running.

• Use an approved fuel container and add half the gas first.
• Measure oil with a marked bottle or measuring cup.
• Add the oil, then add the remaining gas.
• Cap and shake to fully blend.
• Label the can with the ratio and date.

A 2-cycle engine depends on the oil in the fuel for lubrication. Running lean on oil can accelerate wear on the piston and cylinder; running too much oil can increase deposits that restrict exhaust flow (including the spark arrestor) and hurt performance.

If your saw is hard to start or runs rough after a fuel change, use our tips for a hard to start chainsaw checks (fresh mix, correct choke use, clean air filter, and exhaust screen inspection).

Yes. The Craftsman 358341900 gas chainsaw uses a fuel filter inside the fuel tank; it strains debris out of the fuel before it reaches the carburetor, helping prevent hard-starting and rough running. For the exact fuel system layout, use the Craftsman 358341900 owner's manual.

On most gas chainsaws like the Craftsman 358341900, the fuel filter is attached to the end of the fuel pickup line inside the tank.

• Sits in the fuel tank, not in an external inline housing
• Filters dirt and degraded fuel residue before it reaches the carburetor
• Can clog over time and restrict fuel flow
• Can fall off the pickup line if the line hardens or cracks

A restricted filter often shows up as fuel starvation symptoms.

Before replacing parts, we use these basic checks to confirm fuel delivery:

• Drain old fuel and refill with fresh, properly mixed fuel
• Inspect the fuel cap seal and tank venting; a vacuum in the tank can mimic a clogged filter
• Look for cracked or stiff fuel lines; if the line is deteriorated, replace it as a set
• If the filter is dirty or the line is brittle, replace the fuel line components using the chainsaw fuel line kit 580727101

A clean fuel filter protects the carburetor and keeps the correct fuel-air mix. When the filter plugs up, the engine runs lean, loses power, and becomes harder to start, which can also increase wear over time.

A 42cc gas chainsaw typically produces about 2.0 to 2.5 horsepower. For the Craftsman 358341900 specifically, horsepower varies by engine design and tuning, so we use cc-to-HP ranges and confirm performance details in the 358341900 owner's manual.

Most 2-cycle 42cc homeowner and light commercial saws fall into a narrow output band:

• Typical output: 2.0 to 2.5 HP
• Common “advertised” number: around 2.3 HP
• What changes the number: porting, carburetor calibration, muffler/spark arrestor condition, and altitude
• What does not change: engine displacement (42cc stays 42cc)

If your Craftsman 358341900 feels underpowered, we focus on the most common power-robbing issues:

• Old fuel or incorrect 2-cycle mix ratio
• Plugged muffler screen or damaged spark arrestor 545006056
• Restricted fuel delivery (cracked lines, loose fittings, air leaks)
• Dull chain or incorrect chain tension
• Carburetor settings drifting, or intake leaks

Horsepower is only part of cutting performance. Chain sharpness, bar/chain match, and steady fuel delivery often make a bigger difference than a few tenths of a HP in a 42cc saw.

The Craftsman 358341900 is a gas-powered, 2-cycle chainsaw in the 42 cc class that’s commonly set up with an 18-inch bar and chain for homeowner cutting tasks like limbing and bucking. For the exact operating features and specifications for your unit, use the 358341900 owner’s manual.

This type of Craftsman chainsaw is built for general property maintenance where you need portable cutting power.

• Limbing and trimming branches
• Cutting firewood rounds (bucking)
• Storm cleanup and downed limbs
• Occasional felling of small trees (with proper technique and PPE)
• Work where an 18-inch bar length is a practical balance of reach and control

Because chainsaw naming can be confusing, here’s how to interpret the common description.

Routine maintenance keeps a 2-cycle saw starting easier and cutting safer.

• Fuel system parts (cap, lines, fittings)
• Recoil starter components
• Chain brake components
• Clutch and clutch drum
• Oiling system components

If you’re chasing a fuel smell, leaks, or priming issues, the fuel cap assembly 580940901 and chainsaw fuel line kit 580727101 are common service items on this model.

Knowing the model (358341900) and the typical 42 cc, 2-cycle, 18-inch configuration helps you match the correct chain, fuel system parts, and tune-up items. It also ensures you follow the right starting and fueling procedure for a 2-cycle engine.

A Craftsman 16-inch, 36cc gas chainsaw does not map to one single model number; Craftsman used multiple 16-inch/36cc variants over time. For the chainsaw on this page, the model number is 358341900 (Craftsman gas chainsaw). Use the 358341900 owner's manual to confirm the exact identification details for your unit.

We recommend matching the model number from the saw itself (not the bar or chain). Check these common locations:

• Starter housing (recoil starter cover)
• Rear handle area near the trigger
• Under the top cover near the air filter
• On a sticker/plate near the fuel tank
• On the crankcase area (sometimes stamped)

Bar length and cc help narrow it down, but they are not unique identifiers.

The model number controls the correct fit for critical items like the fuel system, clutch, and chain brake. For example, if you are troubleshooting fuel leaks or hard starting, the correct model number ensures you get the right fuel cap and fuel line parts such as the fuel cap assembly 580940901 or the chainsaw fuel line kit 580727101.

Many Craftsman gas chainsaws use a 358-prefix model format. Once you locate the full number, match it exactly (all digits) before ordering parts or following repair steps.

On the Craftsman chainsaw model 358341900, the model number is typically on the product ID label or data tag on the saw body, often near the rear handle, starter housing, or fuel tank area. Check the label first, then confirm the exact characters against the 358341900 owner's manual.

We recommend checking these spots in order because they are the most common on gas chainsaws:

• Rear handle area (side or underside of the handle)
• Starter/recoil housing (near the pull cord cover)
• Fuel tank area (near the fuel cap or on the tank wall)
• Bottom of the powerhead (underside label)
• Chassis/frame tag (a small stamped or printed ID tag)

Most chainsaw model labels include a few identifiers. Use the model number for parts lookup and the serial number for age tracking.

If the sticker is scratched, painted over, or peeling, these steps usually solve it:

• Wipe the area with a damp rag and mild soap; dry fully
• Shine a flashlight across the label at an angle to make faint print readable
• Check for a secondary tag on the underside or near the fuel tank
• Compare the saw’s configuration (bar mount, chain type, handle style) to the diagrams in the 358341900 owner's manual

Using the exact model number (including every digit) prevents ordering the wrong parts, especially for common service items like a fuel line kit, chain brake assembly, or recoil starter repair kit.
