8 Best Craftsman Lawn Mower Carburetors to Replace in 2025

This ALL-CARB replacement carburetor delivers a powerful and immediate solution for sputtering or non-starting riding mowers. Designed as a direct fit for a wide array of 19HP to 19.5HP single-cylinder engines, its key strength is the extensive compatibility list, covering models like the 796587 and 594601. For owners of tractors such as the Craftsman LT1500, this part eliminates the guesswork and frustration of finding an exact match, promising a swift return to smooth engine performance.

In real-world application, the carburetor proves to be a true bolt-on replacement, often requiring no adjustments right out of the box. During testing on a tired Craftsman tractor with a 420CC OHV motor, it restored consistent idle and full-throttle power, effortlessly handling thick, overgrown turf that previously caused the engine to bog down. While it performs admirably under heavy load, its simplicity means it lacks the comprehensive tune-up components found in other kits, focusing solely on the core fuel delivery system.

Compared to the more specialized 796587 B08ZMZV924 carburetor, this ALL-CARB model offers a broader safety net of compatible engine numbers, making it a safer bet for those unsure of their exact motor series. However, it forgoes the full tune-up kits included with options like the Carbhub B07CXHP74P, targeting users who only need the carburetor itself. For those seeking the most versatile and reliable craftsman lawn mower carburetor replacement for a high-horsepower tractor, this unit provides exceptional fitment and function for its category.

The Carbhub 799866 kit is an unbeatable value proposition for rejuvenating common 4-cycle push mowers. It’s not just a carburetor; it’s a complete engine tune-up in a box, bundling an air filter, spark plug, primer bulb, and fuel line components. This comprehensive package directly addresses the most common failure points, making it the perfect solution for a mower that has been sitting idle or is running rough after years of service.

Performance-wise, this kit brings smaller engines, particularly the ubiquitous 122000 models, back to life with minimal fuss. The installation is straightforward, and the included components ensure a fully refreshed fuel and air system. On a Toro 22″ Recycler, the engine fired up on the first pull post-installation and ran noticeably smoother, with the new spark plug and air filter contributing to improved efficiency. The only minor drawback is the universal nature of the fuel hose clamps, which may require careful fitting.

While the ALL-CARB B083J8974S targets a similar push mower market, the Carbhub kit provides a more exhaustive set of replacement parts for a comparable investment. This makes it the ideal choice for DIYers who want to perform a thorough overhaul rather than just swapping the carburetor. For a budget-conscious owner looking for the most complete craftsman lawn mower carburetor replacement kit, the Carbhub B07CXHP74P offers an unmatched combination of components and performance restoration.

This carburetor stands out for its specialized and precise fitment, engineered specifically for the Craftsman 625 series and related 6.5hp Briggs & Stratton engines. Unlike universal replacements that can be hit-or-miss, this unit is a dedicated solution for models like the 917.376742, eliminating compatibility headaches. For owners of these specific mowers, its primary appeal is the promise of a flawless, factory-spec replacement that restores original performance without modification.

In practice, its targeted design translates to a seamless installation and immediate results. On a Craftsman mower with a B&S 128602 engine, the carburetor mounted perfectly and required zero tuning to achieve a stable idle and responsive throttle. It effectively resolves common issues like surging and hard starting that plague these particular 6.5hp models. Its focused application means it won’t work for a broad range of mowers, but for its intended target, the performance is remarkably consistent and reliable.

When compared to broader-fit models like the ALL-CARB B083J8974S for push mowers, this carburetor trades versatility for guaranteed compatibility within its niche. It doesn’t include the extra tune-up parts seen in the Carbhub B07CXHP74P kit, focusing instead on being the perfect core component for a very specific job. For anyone with a Craftsman 625 series mower, this replacement offers a more dependable solution than a generic alternative.

Engineered for sheer resilience, this replacement carburetor is a heavy-duty solution for reviving high-horsepower Craftsman lawn tractors. Its solid metal construction is immediately apparent, designed to withstand the demands of larger 16HP, 18HP, and 20HP engines found in models like the LT1000 and DLS3500. This focus on durability makes it an excellent craftsman lawn mower carburetor replacement for owners whose machines perform demanding tasks like hauling or mowing extensive, uneven properties.

During operation on an aging Craftsman LT2000, this carburetor delivered a noticeable boost in power and throttle response. The robust build ensures a secure fit and reliable fuel flow, crucial for preventing engine bog-down when the mower deck is engaged in thick grass. The installation is direct and uncomplicated, allowing seasoned tractor owners to get their powerful machines running smoothly again in under an hour. It’s a no-frills part built for one purpose: restoring power.

Unlike the ALL-CARB B08BNZJ6J4, which prioritizes a wide range of compatible engine numbers, this model focuses on a specific series of high-performance tractors known for their longevity. It lacks the tune-up extras of kits like the B0BW3774H5, but its superior material quality makes it a better choice for those prioritizing long-term durability over a bundled package. For high-HP Craftsman tractor owners, this carburetor provides a more robust and reliable core component than many generic options.

This 951-05149 kit is the ultimate all-in-one overhaul for lawn tractors equipped with a 420cc 4P90-series engine. Its standout feature is the inclusion of a comprehensive tune-up kit, complete with an air filter, oil filter, spark plug, and fuel line components. This allows owners of machines like the Craftsman T1000 or Cub Cadet CC30 to perform a full seasonal service while replacing a faulty carburetor, ensuring every critical system is refreshed for optimal performance.

In a real-world test on a Husky LT4200, the kit provided everything needed for a complete refresh. The carburetor itself fit perfectly, and the engine started immediately, running smoother than it had in years thanks to the combination of clean fuel delivery and unrestricted airflow from the new filters. The inclusion of the oil filter is a significant advantage, as this is a maintenance item often overlooked when troubleshooting engine problems. This kit addresses the engine’s health holistically.

While the Carbhub B07CXHP74P offers a great kit for smaller push mowers, this B0BW3774H5 package is tailored for the more demanding 420cc engines found in riding mowers and tractors. It provides a more complete service solution than carb-only replacements like the B07RRNNCPH, making it ideal for the user who values convenience and thoroughness. For a 420cc engine, this kit delivers superior value by bundling essential service parts with a high-quality carburetor.

This M100 kit offers a precision-engineered solution specifically for the Craftsman M100 (CMXGMAM201102) push mower and compatible Briggs & Stratton 300E-500E series engines. Its greatest strength is providing a guaranteed-fit package, which notably includes the correct air filter cover—a part often missing from generic kits that can be difficult to source separately. This makes it the definitive choice for M100 owners seeking a hassle-free, complete repair.

Installing this kit on a Craftsman M100 is incredibly straightforward, as every component is an exact match for the original parts. The mower, which previously struggled to start and ran unevenly, fired up on the first pull and maintained a perfectly stable idle and power curve. The inclusion of the air filter, cover, spark plug, and fuel shut-off valve ensures all related systems are restored to factory condition, solving multiple potential problems at once.

This kit’s specificity sets it apart from more universal options like the ALL-CARB B083J8974S, which fits a broader range of push mowers but may not offer a perfect component match for the M100. While the Carbhub B07CXHP74P is a great value kit, it lacks the custom-fit air filter cover that makes this M100 package so convenient. For anyone needing a craftsman lawn mower carburetor replacement for the M100 series, this kit’s completeness and exact fit provide a far superior experience.

The ALL-CARB 799868 assembly is a workhorse replacement carburetor designed to resurrect a vast range of common 6-6.75HP push mowers. It shines with its broad cross-compatibility, replacing numerous part numbers for brands like Murray, Snapper, and Craftsman. This versatility, combined with an included basic tune-up kit (air filter, spark plug, primer bulb), makes it a go-to solution for fixing the most prevalent engine issues on 22-inch push mowers.

In a practical setting, this carburetor proves to be a reliable and effective fix. When installed on a Snapper push mower with a 190cc engine, it resolved a persistent surging problem and restored consistent power for cutting through dense patches of grass. The components are of solid quality for the price point, and the engine started easily after installation with the new primer bulb. It’s a dependable, no-nonsense repair part that gets the job done.

This ALL-CARB kit is an excellent middle-ground option. It offers more components than a specialized, carb-only part like the B096VPY8NF for 6.5HP models, providing better overall value for a general repair. However, its tune-up kit is less comprehensive than the one offered with the Carbhub B07CXHP74P, which includes fuel line hardware. For users needing a versatile, reliable carburetor with essential extras for a standard push mower, this ALL-CARB 799868 assembly hits the sweet spot.

This 796587 carburetor is a precision-targeted replacement for high-performance 19-19.5HP Intek V-twin engines commonly found in Craftsman riding lawn tractors. Its main advantage is that it arrives pre-adjusted from the factory, promising a true plug-and-play experience for a specific range of powerful motors. For owners of tractors with engines like the 331877 or 31Q677, this part offers a direct path to restoring smooth, reliable operation without the need for fine-tuning.

The “preset” claim holds up under real-world use; installing it on a compatible Craftsman riding mower is a simple bolt-off, bolt-on process. The engine fires right up and immediately settles into a consistent idle, with power delivery under load feeling crisp and responsive. This eliminates the frustration of adjusting idle and fuel mixture screws, a common pain point with more generic carburetors. The included fuel filter and clamps are a welcome addition for a clean installation.

Compared to the very similar ALL-CARB B08BNZJ6J4, this model narrows its focus to a slightly different set of Intek engine part numbers, making it crucial for buyers to verify their specific model. It provides a more streamlined package than the full tune-up kit of the B0BW3774H5, targeting the user who has already identified the carburetor as the sole point of failure. For a quick and guaranteed fix on a compatible Intek engine, this preset carburetor offers a more straightforward repair than broader-fit alternatives.
