8 Best Craftsman Snow Blower Carburetors of 2025

This budget-friendly carburetor kit delivers far more than its price suggests, making it a standout for DIYers reviving older Craftsman snow blowers. Engineered as a direct replacement for models like the 247.889701 and 247.886910, it’s built to handle Huayi 170SA/170SB and MTD 270-QU engines with precision. What truly sets it apart is the comprehensive hardware bundle—including gaskets, fuel hoses, clamps, and even a shut-off valve—saving users from hunting down small, easily lost components. For weekend mechanics battling a stubborn engine that won’t start after winter storage, this kit tackles the most common carburetor-related failures head-on.

In real-world testing, the carburetor showed solid cold-start performance and consistent fuel delivery across multiple 170cc engine platforms. It integrates seamlessly with ZS365-SUA and 952Z265-SUA engine variants, maintaining smooth idle and throttle response once tuned. While it doesn’t come pre-adjusted to factory specs, minor tweaking with a screwdriver typically brings it up to optimal performance. That said, users with zero mechanical experience may find the lack of adjustment instructions slightly challenging—this isn’t a true plug-and-play unit without some basic know-how.

Compared to pricier alternatives like the Hipa or Pro Chaser versions, this model holds its own by offering near-identical compatibility and included parts at a fraction of the cost. It’s not quite OEM-grade in finish, but for those needing a reliable, no-frills fix for a Craftsman that’s been sitting for years, it’s an outstanding value. If you’re weighing cost against functionality, this kit beats out more expensive options when raw performance and fitment are the priorities—not bells and whistles.

The Hipa Storm 2620 carburetor kit isn’t just a replacement—it’s a full engine revival package, especially for owners of Troy-Bilt and Craftsman two-stage snow throwers. What immediately grabs attention is the inclusion of an ignition key and spark plug—components rarely found in standard carb kits—making this a true all-in-one solution for engines that sputter or fail to turn over. Designed to replace 951-12705 and 951-14027A models, it’s tailor-made for 208cc Powermore and Huayi 170S engines, offering seamless integration with popular models like the Troy-Bilt Storm 2620 and Craftsman 247.881731.

During field testing on a sluggish 2008 Storm 2410, the kit delivered noticeably smoother ignition and throttle response, eliminating the hesitation that plagued the original carb. The included gaskets and fuel lines fit perfectly, reducing leak risks, while the new spark plug contributed to faster cranking. However, the ignition key, while convenient, may not be necessary for users who already have a working one—adding cost without always adding value. Still, for someone rebuilding an engine from scratch or troubleshooting multiple failure points, having everything in one box is a major time-saver.

Against the Pro Chaser or basic 247.889571 kits, the Hipa stands out for total system readiness, but it’s overkill for simple carb swaps. It’s ideal for users who want to eliminate multiple potential failure points at once—especially on high-mileage machines. While it costs more than most, the value shines when you factor in reduced part-hunting and labor time, making it a smarter buy than buying components separately.

If you’re nursing an older Craftsman 21″ snow blower back to life, this precision-fit carb kit for 123cc Powermore engines is a godsend. Tailored specifically for 2008–2009 models like the 31A-2M1A799 (247.88704), it replaces obsolete part numbers 951-10956 and 951-10956A with a factory-tested, pre-calibrated unit that installs straight out of the box. For vintage small-engine owners, this level of specificity is rare—and invaluable—since many universal kits fail to account for subtle throttle linkages or fuel bowl angles on older designs.

In practice, the carburetor delivers reliable cold starts and stable idle without requiring tuning, a major win for users who dread carb adjustments. It bolts directly onto the Powermore OHV engine, maintaining proper air-fuel ratios even after repeated use. While it lacks extra hardware like hoses or clamps, the no-nonsense design ensures compatibility isn’t compromised by generic fittings. That said, it’s not suited for larger or newer models—its strength is also its limitation.

Compared to broader-fit kits like the B0771HNWWC, this model wins on authenticity and ease of use for its niche. It doesn’t try to do everything—just what it’s meant to, perfectly. For owners of these specific vintage Craftsman blowers, it offers a level of confidence you won’t find in universal replacements, making it a must-have for targeted restoration projects where OEM accuracy matters most.

Engineered for the MTD 270-WU and 670-WU engine families, this Huayi-sourced carburetor is the go-to fix for two-stage snow blowers that have developed fuel starvation issues. With exact fitment for models like the 31AS6BEE799 (247.881732), it’s a precise match for 208cc Troy-Bilt Storm 2410 and select Craftsman blowers built on the same MTD platform. The 951-15236 replacement spec ensures OEM-level compatibility, and the Huayi 170SD/175SC design means it handles high-output cold-weather operation without vapor lock or flooding.

Real-world performance shows excellent fuel metering and throttle transition, even after extended runs in sub-zero conditions. It pairs perfectly with the 270-WUA engine’s governor system, preventing surging and maintaining consistent RPM under load. However, the kit includes only the carburetor and no gaskets or fuel lines, which can be a snag if your old ones are brittle or missing. Users must source seals separately, which adds minor hassle and cost.

When stacked against the Snow Blower Carburetor B0771HNWWC—which covers similar models—this unit wins on engine-specific accuracy and airflow efficiency. It’s not the most inclusive kit, but for owners of MTD 270-WU series machines, it’s the most technically correct choice. It delivers professional-grade reliability without the markup, making it the top pick when exact model alignment is non-negotiable.

For owners of 208cc two-stage snow blowers, this high-coverage carburetor is a powerhouse of compatibility, supporting everything from Craftsman 247.881731 to Troy-Bilt Storm 2620 and Cub Cadet 524SWE models. It replaces critical OEM numbers like 951-14026A and 951-12705 while supporting Huayi 170S, 170SA, and MTD 270-SUA engines—making it one of the most versatile options for modern single-cylinder snow throwers. Its broad fitment list means it’s often the only kit you’ll need in your repair arsenal.

Testing on a Craftsman 247.886914 revealed strong cold-start capability and smooth acceleration, with no bogging during heavy snow loads. The carb maintains clean combustion and resists clogging when using ethanol-blended fuels, thanks to its updated jet design. While it doesn’t include hoses or clamps, the threading and mounting pattern match OEM perfectly, reducing installation time. Still, some users reported needing to clean the fuel inlet screen after a few uses—likely due to debris stirred up from old tanks.

Against the Pro Chaser B07WLXGB1V, it offers nearly identical fitment but at a slightly higher cost, without adding extra hardware. However, its strength lies in being a universal solution for 208cc engines across brands. If you service multiple MTD-platform snow blowers, this is the most efficient single purchase. It balances breadth, reliability, and performance better than most, making it ideal for technicians and serious homeowners alike.

The Pro Chaser 247.889571 carburetor is engineered for one job: replacing worn carbs across a massive range of Craftsman snow blowers—and it nails the brief. With compatibility spanning over 20 models—from 247.889701 to 247.881730—it’s the most versatile direct-fit option for Sears-branded machines. Built to replace 951-12705 and 951-14026A, it integrates flawlessly with Huayi 170SA/170SB and MTD 270-QU engines, offering a level of brand-specific precision that generic kits can’t match.

In real snow-throwing conditions, the carburetor delivers consistent fuel flow and quick starts, even after prolonged storage. The included kit—gaskets, hoses, clamps, fuel filter, and primer bulb—eliminates the need for secondary purchases, and all parts are correctly sized and pre-cut, reducing installation errors. It performs exceptionally well on 170cc engines, maintaining idle stability and throttle response. That said, like many aftermarket units, it may require minor idle screw tuning to reach peak efficiency.

Next to the budget 247.889571 kit (B0CJ58JSXL), the Pro Chaser offers identical components at a slightly higher cost, with no performance edge. However, its reputation for consistent quality control gives it an edge for users who can’t afford returns or delays. For Craftsman loyalists who want a drop-in, complete solution without hunting for parts, it’s the smarter long-term bet—especially when reliability trumps rock-bottom pricing.

This OEM-grade Huayi carburetor for the Craftsman SB450 26″ snow blower (Model 31AM6BHF793) is the gold standard for replacement parts—delivering factory-level engineering and fit in a single unit. Unlike generic clones, this is a genuine Huayi design, ensuring perfect airflow dynamics and fuel calibration for the 270-WU engine platform. For users restoring a CMXGBAM1054542 or battling persistent stalling, this carb eliminates guesswork with a true plug-and-play experience that just works.

On the job, it delivers crisp throttle response, zero hesitation, and rock-solid idle, even in deep freeze conditions. Installation takes minutes, and the included gaskets seal flawlessly—no leaks, no tuning needed. The build quality surpasses most aftermarket versions, with tighter tolerances and corrosion-resistant plating. While the kit doesn’t include fuel lines or clamps, the focus on core performance means you’re getting the single most critical component done right.

Compared to the B0771HNWWC or Hipa kits, this model is narrower in scope but superior in execution. It’s not meant for multiple models—it’s meant to be the best for one. For owners of the SB450, it’s the only logical choice when performance, longevity, and authenticity matter. It may cost more, but you’re paying for precision engineering, not packaging fluff—making it the best overall carburetor for this specific machine.

Tailored for Tecumseh-powered snow blowers, this 8526 carburetor is a lifesaver for older Troy-Bilt, Craftsman, and Ariens models that rely on discontinued engines. It directly replaces units in the ST824, 826 John Deere, and Craftsman 536.886260—machines that often sit unused for years and suffer from varnish-clogged carbs. What makes this kit shine is its comprehensive hardware bundle, including fuel hoses, clamps, filter, primer bulb, and shut-off valve—everything needed for a full rebuild.

In testing on a 1990s-era Craftsman with a Tecumseh 8HP engine, the carb restored strong compression and smooth idle after a complete teardown. It handles ethanol-blended fuels better than original carbs, thanks to updated diaphragm materials. However, jetting is slightly lean out of the box, requiring minor adjustment for optimal performance in cold starts. Also, the mounting pattern, while correct, can be finicky on older castings with warped flanges.

Against universal kits, this model excels by addressing a dying niche—Tecumseh engines no longer supported by OEM parts. While the B0CJ58JSXL might be cheaper, it doesn’t fit these engines at all. For owners of vintage throwers, this carb is irreplaceable, offering a second life to machines that would otherwise be scrap. It’s not flashy, but for legacy engine revival, it’s unmatched.
