Finding reliable components and compatible units for the Stihl MS170 presents clear challenges for homeowners and light professionals. Many users face mismatched chain pitch, gauge errors that cause binding, carburetor replacements that fail under load, and incomplete tune-up kits that leave the saw hard to start. These issues lead to downtime during yard work or small tree maintenance, especially when original equipment is discontinued or overpriced. Shoppers searching for a Stihl Ms170 Chainsaw in the current market must navigate aftermarket quality variations, precise bar length matching, and brand consistency to avoid repeated failures. Selecting from 15 carefully screened options across the $6.99 – $274.94 spectrum helps resolve these pain points without overspending on unnecessary features.
When choosing a Stihl Ms170 Chainsaw in August 2026, prioritize exact chain specifications of 3/8 inch LP pitch, .043 inch gauge, and 55 drive links for 16 inch bars, plus verified carburetor interchangeability with C1Q-S57A or C1Q-S57B models and complete air filter plus spark plug kits for reliable starts. These criteria deliver the highest compatibility and cut performance based on technical matching to original Stihl MS170, MS171, MS180, and 017/018 platforms. Reviewers seeking deeper context on similar platforms can benefit from understanding the core specifications of related Stihl chainsaws before finalizing a purchase.

Overview: The STIHL 61PMM355E is a genuine replacement saw chain built for compatible Stihl chainsaws, including the 017, MS170, and MS180 when paired with a 16-inch bar. Its OEM branding and exact specifications make it a straightforward option for users who need a chain that matches the saw closely.

It is positioned as a practical fit for several Stihl, Poulan, and Troy-Bilt saws, but exact compatibility should always be checked first.
Performance: The chain is described as low-kickback and low-vibration, which can make cutting feel more controlled and less tiring. A hard chrome outer layer and hardened rivets are intended to improve wear resistance and help the chain hold up better during regular use.
Considerations: This is not a universal chain, and some saws in the supported model list may use either .043" or .050" gauge, so confirming the old chain specs is important. The listing also does not provide extra accessories or detailed sharpening information.

KAKEI specifies Germany steel, hardened and quenched rivets, and Japanese chrome-plated cutter technology, all intended to improve toughness, wear resistance, cutter durability, and cutting sharpness.
Drawbacks & Considerations: The most important consideration is fitment. The product data specifically notes that some bars may take either .043 inch or .050 inch gauge chain, so buyers should verify pitch, gauge, length, and drive link count using the owner’s manual or the guide bar side stamp before purchasing. This listing includes one chain only, which may not be enough for users who prefer to keep spares on hand.
Verdict: The KAKEI 61PMM3 55 is a practical choice for chainsaw owners who need a 16 inch, .043 gauge, 55-drive-link semi-chisel chain for a compatible Stihl setup.

Stihl Ms170 Chainsaw Buying Guide
Selecting the right Stihl Ms170 Chainsaw requires matching technical dimensions, material durability, and kit completeness rather than relying solely on brand recognition. The following criteria focus on real-world fitment for Stihl MS170 series saws and practical maintenance needs.
Chain Pitch, Gauge, and Drive Link Count
Exact chain geometry determines safe and efficient cutting. For the Stihl MS170, the standard is 3/8 inch LP pitch combined with .043 inch gauge and 55 drive links on a 16 inch bar. Using a .050 inch gauge chain on a .043 inch bar causes binding and accelerated rail wear. Semi-chisel cutters offer a balance of speed and durability for mixed softwood and hardwood. Always confirm the model code such as 61PMMC3-55 or Oregon R55 equivalent before ordering. Multi-packs provide economical replacements and allow rotation to maintain sharpness.
Carburetor Compatibility and Jetting
Carburetors must match Zama C1Q-S57A or C1Q-S57B specifications with the correct 1130 120 0603 mounting. Aftermarket units from Savior or Butom often include pre-set jets suitable for standard 50:1 fuel mix. A poorly matched carburetor produces hard starts, flooding, or high idle. Inspect the throttle shaft and primer bulb integrity during installation. Pairing a new carburetor with a fresh fuel filter prevents debris-related failures and restores original throttle response.
Bar Length and Mounting Pattern
Most MS170 platforms run a 16 inch bar with the narrow .043 inch groove. Replacement bars must match the sprocket nose and mounting stud spacing. Combo kits that include a bar plus multiple chains reduce setup time and ensure matched components. Heavier bars increase cutting capacity but raise fatigue on prolonged jobs. Verify the chain tensioner style and oiling hole alignment to maintain continuous lubrication.
Tune-Up Kit Completeness
A full tune-up kit contains the air filter (part 1130 007 1800), spark plug, and fuel filter. Incomplete kits force separate purchases and risk mismatched components. High-quality filters maintain airflow and prevent debris ingestion that scores the cylinder. Replace these items at regular intervals or after storage seasons to keep compression and ignition reliable. Kits priced near the lower end of $6.99 – $274.94 often deliver the best cost efficiency for seasonal users.
Brand Reliability and Aftermarket Support
OEM Stihl and Oregon components provide dimensional accuracy and longer edge retention. Aftermarket brands such as Savior, Butom, KAKEI, and Mintu fill the value segment with functional equivalents. Evaluate packaging clarity and listed cross-reference numbers. For users comparing platforms, the broader selection of Chainsaws available on the site offers additional context on brand consistency across similar light-duty models.

Testing & Selection Methodology
We evaluated 15 items by cross-referencing manufacturer part numbers against original Stihl MS170, MS180, 017, and 018 documentation. Comparison focused on dimensional accuracy (pitch, gauge, drive link count, mounting hole patterns), material descriptions where available, completeness of included components, and price positioning within $6.99 – $274.94. Brand reliability was assessed through known interchangeability of Stihl and Oregon parts versus aftermarket cross-references. User satisfaction metrics and warranty language were reviewed where published. No physical dynamometer or field cutting tests were performed; rankings derive strictly from specification alignment and documented fitment data. This process isolates options that minimize installation errors and maximize operational uptime for light-duty cutting tasks.
Best Picks & Final Verdict
After systematic comparison of the full set, three recommendations stand out for distinct buyer needs. These selections balance specification fidelity, component completeness, and value within the available $6.99 – $274.94.

Frequently Asked Questions
What chain size fits a Stihl MS170 chainsaw?
The Stihl MS170 requires a 16 inch chain with 3/8 inch LP pitch, .043 inch gauge, and 55 drive links. Matching these three measurements prevents binding and ensures proper oil delivery. Aftermarket chains listed as 61PMMC3-55 or Oregon R55 equivalents work when they carry the same specifications.
How often should I replace the carburetor on an MS170?
Replace the carburetor when the saw floods, will not idle, or loses power under load after fuel system cleaning. Compatible units such as those matching C1Q-S57A or C1Q-S57B restore factory mixture settings. Pair the new carburetor with a fresh fuel filter for best results.
Can I use a .050 gauge chain on a Stihl MS170?
No. The MS170 bar groove is designed for .043 inch gauge. A .050 inch chain will bind, overheat, and damage both the bar and drive sprocket. Always verify gauge before purchase. For broader chainsaw guidance explore the full Chainsaws category resources.
What is included in a complete MS170 tune-up kit?
A complete kit contains the air filter (1130 007 1800 or equivalent), spark plug, and fuel filter. Some kits also list primer bulbs or additional gaskets. Confirm all three core items are present to avoid incomplete service.
Is the Stihl MS162 a direct substitute for the MS170?
The MS162 is a modern light-duty Stihl platform that shares similar 16 inch bar and chain requirements but differs in engine displacement and features. It can serve as a replacement power head when the original MS170 is beyond economical repair. Check current bar and chain compatibility before transferring components.
