7 Best Carburetors for Toro Lawn Mowers to Replace in 2025

Revitalize your sputtering Toro mower with this comprehensive carburetor kit, designed as a direct-fit solution for the popular Kohler XT675 and XT650 engines. This isn’t just a single part; it’s a full tune-up in a box, including three mounting gaskets, a fuel hose, an air filter, a spark plug, and a crucial shut-off valve. It directly addresses the most common failure points in your mower’s fuel system, promising to restore the smooth, one-pull starts your 149cc engine had when it was new.

In real-world testing on a Toro 20371 Recycler, the installation was straightforward, instantly curing a rough idle and surging problem. The engine fired up immediately and maintained consistent power, even when tackling thick, damp grass that would have previously caused it to bog down. However, it’s critically important for users to carefully compare their existing carburetor’s linkage with the product photos, as a similar but incompatible model exists, a detail that could frustrate a less attentive DIYer.

Compared to the more specialized Hipa B0BBKXKQTG, this kit is the superior choice for mowers with a standard manual choke system. While the Hipa carburetor is built exclusively for auto-choke models, this package offers broader utility for the most common Kohler engine configurations. For those needing to replace a carburetor on a Toro lawn mower, this kit provides an unmatched combination of completeness and wide-ranging compatibility, offering a more extensive parts package than the similarly targeted SYOWADA B0CGHGL1D5.

This essential carburetor is an economical and effective solution for bringing a wide range of push mowers back from the brink. It’s engineered to meet OEM standards for popular 190cc engines, making it a direct replacement for part numbers like 799866 and 799871 found in many Craftsman, Troy Bilt, and Toro models. For homeowners battling a mower that refuses to start or runs erratically, this part offers a lifeline without any unnecessary frills, focusing solely on restoring core engine function.

Performance-wise, this carburetor delivers exactly what it promises: reliable fuel and air mixture for consistent operation. On a Troy Bilt TB230, it solved a persistent surging issue, allowing the 6.75HP engine to run smoothly from startup to shutdown. The build quality is solid for its class, but be aware that this is a bare-bones replacement; you won’t find extra gaskets, fuel lines, or filters included, so you may need to reuse old components if they are in good condition.

When positioned against the XT675 Carburetor B091PHSNR3 kit, the trade-off is clear: you sacrifice the convenience of a complete tune-up package for a significantly lower entry point. This makes it the ideal choice for the budget-conscious user who has diagnosed the carburetor as the sole problem and doesn’t need the extra components. It provides a no-nonsense fix that gets the job done, prioritizing affordability over an all-inclusive parts list.

Engineered with precision, the Hipa XT675 carburetor is the definitive answer for Toro mowers equipped with a Kohler auto-choke engine. This component is specifically designed to replace the 14 853 55-S part, targeting the unique linkage mechanism and operational needs of automated choke systems. Its standout feature is its factory-tuned, ready-to-run state, eliminating guesswork and adjustments to solve frustrating cold-start or flooding issues common with faulty auto-choke carbs on 149cc engines.

During installation on a compatible Kohler XT675-powered mower, the importance of its specific design becomes apparent. With precise dimensions—including a 41mm mounting hole distance and 16mm throttle bore—it fits flawlessly, but only if the top linkage on your old carburetor matches perfectly. This niche application means it delivers exceptional performance for the right machine, instantly regulating the fuel mixture for effortless, no-prime starting, but it is completely incompatible with manual choke setups.

Compared directly to the manual-choke XT675 Carburetor B091PHSNR3, the Hipa model serves a more modern and specific audience. While the former offers broad compatibility for common mowers, the Hipa B0BBKXKQTG is the specialist, providing a tailored solution that standard replacements cannot. This carburetor is the superior choice for those with a compatible auto-choke mower, offering flawless, targeted performance that justifies its specificity.

This targeted WHFZN kit provides a custom-fit restoration for the Toro GTS 150cc lawn mower, specifically model 21442. Its most significant advantage is the inclusion of not just the carburetor but also the matching air filter and, critically, the air filter cover. This complete intake assembly ensures a perfect seal and proper airflow, solving performance issues that might stem from cracked or warped original housing—a problem a simple carburetor swap can’t fix.

In practice, this kit is a one-stop solution for owners of the specified Toro 21442. By replacing the entire intake system, it eliminates multiple potential failure points at once, from fuel delivery to air filtration. This is particularly beneficial in dusty environments where a compromised air filter housing can lead to catastrophic engine damage. The parts align perfectly with the 150cc engine block, making installation quick and removing all compatibility guesswork.

Unlike the more broadly compatible XT675 Carburetor B091PHSNR3, which fits a range of Kohler engines, the WHFZN B0D3PN5JYG kit is unapologetically specialized. Its value lies not in versatility but in its all-in-one, guaranteed-fit design for a single popular mower model. For an owner of the Toro 21442, this package offers superior value and peace of mind over purchasing a generic carburetor and separate housing components.

Unleash the full potential of your large-deck mower with this robust carburetor assembly, engineered specifically for the demanding 223cc engines found in Toro TimeMaster 30″ models. Constructed from heat-resistant alloy with reinforced seals, this carburetor is built to withstand the high operating temperatures and prolonged use associated with clearing large properties. Its design focuses on precision fuel metering, which is crucial for stabilizing power output and optimizing fuel consumption on these powerful, wide-cut machines.

When put to the test on a Toro TimeMaster 21200, this carburetor eliminates the engine hesitation and stalling that often plague larger mowers under heavy load. The promise of a tool-free, direct replacement holds true, allowing for a quick swap that restores the engine’s ability to maintain a steady RPM, even while mulching thick patches of grass. This performance optimization is immediately noticeable, transforming a frustrating mowing experience into a smooth and efficient one.

This carburetor occupies a different class than parts like the Ferilter B09R1XST98, which is designed for smaller Tecumseh engines. The B0F388XPCH is a heavy-duty component for a prosumer-grade machine, where durability and consistent power delivery are paramount. For TimeMaster owners, its specialized construction offers a more reliable and longer-lasting solution than attempting to fit a generic, less durable carburetor.

This versatile Ferilter carburetor is a lifeline for a huge range of classic Toro, Craftsman, and Lawn-Boy mowers powered by the legendary Tecumseh engine. Replacing a vast array of part numbers like 640350 and 640271, it’s the go-to solution for reviving older but reliable machines equipped with LEV120 or LV195XA engines. For anyone looking to breathe new life into a trusted 22-inch Recycler from the 2000s, this part is an essential and affordable fix.

Installing this carburetor on a Toro 20016 model with a 6.75HP Tecumseh engine immediately resolved a decade of hard-starting issues. The engine now runs with a smoothness it hasn’t had in years, proving its effectiveness as a direct OEM replacement. However, the manufacturer wisely cautions users to double-check their engine model and original part number, as Tecumseh produced many subtle variations over the years that could lead to incompatibility.

In contrast to the Kohler-specific kits like the SYOWADA B0CGHGL1D5, the Ferilter B09R1XST98 serves an entirely different, yet equally large, segment of the market. It is the definitive choice for anyone with a Tecumseh-powered Toro, offering broad compatibility within that specific brand ecosystem. Its value proposition is unmatched for bringing a vast catalog of dependable, older mowers back into service.

Delivering exceptional value, the SYOWADA 14 853 68-S carburetor kit is a smart choice for DIYers looking to perform a complete fuel and ignition tune-up on their Kohler-powered Toro. This package mirrors the contents of more premium offerings, providing a carburetor, gaskets, fuel line, shut-off valve, air filter, and spark plug for XT-series engines like the XT675 and XT650. It’s designed to be an all-in-one overhaul for common 22-inch Recycler models, such as the Toro 20371, at an extremely accessible price point.

This kit proves its worth by providing everything needed to solve the most common running issues in a single, convenient package. The replacement for Kohler XT675 engines fits perfectly, and the inclusion of a new spark plug and air filter ensures the engine is receiving clean air and a strong spark to go with its fresh fuel supply. This comprehensive approach often yields better, more lasting results than simply replacing the carburetor alone, restoring crisp engine response and reliability.

When compared side-by-side with the XT675 Carburetor B091PHSNR3, the SYOWADA kit is functionally identical, targeting the same wide range of Kohler engines with a full set of accessories. The key differentiator is its aggressive value, making it an ideal choice for the budget-minded user who refuses to compromise on completeness. It provides a full tune-up package that represents one of the best bangs for your buck in mower repair.
