Best Carburetor For Lawn Mower: Compare 10 Replacement Fits

#1 · Best Overall

1. Briggs & Stratton 594058 Carburetor

Best for: Genuine auto-choke replacement.

Why it ranks #1: Genuine auto-choke replacement lists select 550EX, 625EX, 675EX, and 725EXi engines, replacement numbers 595192 and 596505, and an air cleaner gasket.

A genuine Briggs & Stratton auto-choke carburetor is the defining feature here, with fuel-air metering specified to support smooth starting and operation. Its listed applications include select 550EX, 625EX, 675EX and 725EXi engines, making engine-series identification central to the fit decision.

The auto-choke arrangement meters fuel and air, a function the listing connects with smooth starting and operation. Fitment covers select Craftsman, Troy-Bilt, Husqvarna, Murray and Yard Machines walk-behind mowers and pressure washers, as well as named Briggs & Stratton engine series. The 595192 and 596505 numbers are listed as replacement references, while the included air-cleaner gasket adds a related installation component. Matching the engine model, linkage and existing part is specifically recommended before ordering.

Skip it if you need a replacement for a 125cc or 140cc 300E engine; PSLER's 799583 listing names those series.

A strong match for owners seeking a genuine auto-choke part for a listed Briggs & Stratton engine or compatible mower. Its select-application scope makes engine model, linkage and current part identification essential boundaries before installation.

#2 · Best Seal Kit

2. Rakiyada 799584 Carburetor

Best for: 163cc engine replacement.

Why it ranks #2: Lists 163cc, 6.75–7.25HP engines and replacement numbers 799584, 592361, 594057, 594058, and 594529; two rubber seals are included.

Its 799584 replacement number, also cross-listed as 592361, 594057, 594058 and 594529, gives owners several reference points for identifying the part. The carburetor is specified for 163cc, 6.75–7.25HP engines, including named Troy-Bilt, Craftsman and Toro mower applications.

The listed 163cc engine range and 6.75–7.25HP rating help narrow the search to the mower class this part is meant to serve. Compatibility names include Troy-Bilt TB110 and TB200, Craftsman M110, M220 and M230, and specified Toro 09P702 engine variants. Two rubber seals are included with the carburetor, giving the replacement package those sealing pieces alongside the main component. The long cross-reference list is useful when matching an existing part number, but the engine and mower model still matter.

Skip it if you have a 125cc or 140cc engine; PSLER's 799583 carburetor lists those smaller engine families.

A practical candidate for owners replacing a 799584-family carburetor on a listed 163cc mower, especially the named Troy-Bilt or Craftsman models. Treat engine-series and part-number matching as the boundary; the listed fitment does not cover every mower.

#3 · Broadest Mower Fit

3. BioLion 799584 Carburetor

Best for: Craftsman mower replacement.

Why it ranks #3: Names 550EX through 725EXi, 140cc to 163cc engines, Troy-Bilt, Craftsman, and Toro models, with two gaskets included.

Its compatibility list brings Craftsman M110, M220 and M230 together with Troy-Bilt TB110, TB200, TB210 and TB230 applications. This BioLion carburetor also cross-references five 799584-family part numbers and specifies 140cc, 150cc and 163cc engine series.

The 799584, 594058, 594057, 594529 and 592361 references give owners several ways to compare an existing part. Fitment lists 550EX, 625EX, 675EX and 725EXi engines, plus 09P702, 093J02, 103M02, 104M02, 103M05 and 104M05 codes. A Toro GTS application is also described, with 21442, 21445 and 21465 model numbers. The package lists a carburetor and two gaskets, supporting a replacement workflow that has sealing pieces included.

Skip it if you need a 125cc 300E-series part; PSLER's 799583 listing covers 125cc engines and 300E models.

A good candidate for owners of the named Craftsman, Troy-Bilt or Toro applications who need a 799584-family replacement with two gaskets. Match the engine code and mower model carefully; brand names alone are not enough to establish fit.

#4

4. abliubale 799584 Carburetor

Best for: Broad 799584 engine coverage.

Why it ranks #4: Lists 140cc, 150cc, and 163cc engines, several replacement numbers, and fitment for Troy-Bilt TB110 and TB200 mowers.

Its fitment spans 140cc, 150cc and 163cc engines, setting this abliubale 799584 kit apart for owners comparing several engine sizes. The listing also names 550EX, 625EX, 675EX and 725EXi series, plus Troy-Bilt TB110 and TB200 mowers.

The three stated engine capacities—140cc, 150cc and 163cc—offer a broader size range than a listing limited to a single displacement. Named fitment includes Briggs & Stratton 550EX through 725EXi series and mower engine codes such as 09P702, 093J02, 103M02 and 104M05. Troy-Bilt TB110 and TB200 and Husqvarna LC121P are also listed. This breadth helps owners check several identifiers, but the long list makes matching the specific engine code worthwhile.

Skip it if you need a 125cc 300E-series replacement; PSLER's 799583 listing explicitly covers 125cc and 140cc engines.

Consider this 799584 replacement if your mower falls within its listed engine sizes and series, particularly a TB110, TB200 or LC121P. Its wide compatibility list is useful for cross-checking, but does not replace matching the exact engine code.

#5

5. BlueStars 799584 Carburetor

Best for: TB110 and TB200 owners.

Why it ranks #5: Its listing identifies 799584 and 592361 and names 550EX, 625EX, Troy-Bilt TB110, and TB200, though fitment details are limited.

The BlueStars listing names 550EX and 625EX engines alongside Troy-Bilt TB110 and TB200 mowers, giving it a focused fitment profile. Its 799584 and 592361 identifiers offer two reference points for owners comparing the carburetor they are replacing.

For owners with a Troy-Bilt TB110 or TB200, those model names provide a concrete first check against the listing. The additional 550EX and 625EX references help narrow the fit by engine series, while 799584 and 592361 give part-number identifiers to compare with the existing component. BlueStars describes its products as repair solutions, and this item is recommended for lawn mower use. The supplied specifications do not add a wider engine-size range, so the named models and series are the practical fit boundary.

Skip it if you need a 725EXi replacement; BioLion's 799584 listing includes 725EXi engine fitment.

A focused choice for owners checking a Troy-Bilt TB110 or TB200 with a listed 550EX or 625EX engine. Use the model and part references as fit boundaries; the supplied information does not establish compatibility with other engine series.

#6 · Primer-Engine Fit

6. LEIMO KPARTS 799868 Carburetor

Best for: Primer-system engine match.

Why it ranks #6: Targets Briggs & Stratton 122000-series engines with a primer-type system and lists compatibility with 4–7 hp mower applications.

Its primer-type system fitment is the key identifier for this LEIMO KPARTS carburetor, which lists Briggs & Stratton 122000-family engines and several cross-reference numbers. That combination gives owners a way to compare both engine series and an existing carburetor number before choosing a replacement.

The compatibility listing covers 120XXX, 121XXX, 122XXX, 12EXXX and 12TXXX engines, specifically describing a primer-type system. It also cross-references 498170, 799872, 694202 and other carburetor numbers, helping owners compare the part in hand with the listing. The product is identified for lawn mower use and names Craftsman 6.5hp and Snapper Ninja 6.75hp engines. Since the supplied listing advises checking the picture, visual comparison can help distinguish a matching replacement from a similar-looking variant.

Skip it if you need a 163cc auto-choke replacement; Briggs & Stratton 594058 is identified as an auto-choke carburetor for select engines.

Best suited to owners identifying a primer-system carburetor on a listed Briggs & Stratton 122000-family engine or named Craftsman and Snapper application. Compare engine series and the existing carburetor visually; the primer-system detail is an important fit boundary.

#7 · Smaller Engine Fit

7. PSLER 799583 Carburetor

Best for: 125cc and 140cc push mowers.

Why it ranks #7: Specifies Briggs & Stratton 300E, 450E, 500E, and 550EX engines, plus 125cc and 140cc applications and several replacement numbers.

Its 799583 replacement reference covers Briggs & Stratton 300E, 450E, 500E and 550EX engines, with 125cc and 140cc capacities also specified. That combination makes this PSLER carburetor a targeted choice for owners identifying one of those smaller push-mower engine families.

The listed 799583, 593261, 595656, 591979, 591160 and 590556 references provide multiple identifiers to compare against a removed part. Engine compatibility includes 300E, 450E, 500E and 550EX, with model codes such as 09P602, 09P502 and 08P502 also named. This helps narrow the fit by both series and code rather than relying on mower appearance alone. The supplied description calls installation easy to use, but does not detail included installation components.

Skip it if you have a 163cc 725EXi mower; abliubale's 799584 listing names 163cc and 725EXi fitment.

Best for owners matching a 799583-family carburetor on a listed 300E, 450E, 500E or 550EX engine. Check the engine code and replacement number carefully, especially if your mower uses a larger displacement outside the stated range.

#8

8. Aylux 799583 Carburetor Kit

Best for: Carburetor with filter references.

Why it ranks #8: Lists 300E, 450E, 500E, and 550EX engines and 125cc or 140cc applications, with air-filter and primer-bulb replacement details.

This Aylux 799583 kit names replacement references for both the carburetor and its air-filter components, including filter 799579 and cover 595660. Its fitment covers most listed B&S 300E, 450E, 500E and 550EX engines in the 125cc and 140cc families.

The carburetor cross-references 799583, 593261, 595656, 591979, 591160 and 590556, while the listing separately identifies air filter 799579, cover 595660 and primer bulb 594281. Those component references help owners check whether related air-intake and priming parts correspond to their mower. Engine fitment includes 08P502, 8P502, 09P602 and 9P602, as well as named B&S series. The listing calls these aftermarket replacement components and advises checking the original part number and engine model.

Skip it if you need a genuine OEM auto-choke carburetor; Briggs & Stratton 594058 is identified as a genuine part.

A useful fitment-reference option for owners servicing a listed 300E, 450E, 500E or 550EX mower and checking related filter components. Its aftermarket status and unclear physical kit contents are important boundaries when planning a repair.

#9

9. YKWYKW 799866 Carburetor

Best for: Toro Recycler engine match.

Why it ranks #9: Covers selected 190cc and 6.5–7.5HP mower applications, including Toro Recycler models, but its listed fit is narrower than the higher-ranked options.

Its fitment specifically calls out Toro 6.5–7.5HP Recycler 22 mowers and 190cc engines, giving this YKWYKW carburetor a clear target. Cross-references including 799866, 799871, 790845, 796707 and 794304 help owners compare an existing part number.

The listing pairs a 190cc description with Toro 6.5, 6.75, 7.0, 7.25 and 7.5HP Recycler mower applications. It also names Toro walk-behind models 16401, 20716, 20712, 20713 and 20714, linking the engine range to concrete mower identifiers. Cross-references such as 799866 and 799871 offer another way to identify a replacement, while listed Craftsman 6.75hp engines widen the application set. Verify the specific engine and mower code against these details before replacing the carburetor.

Skip it if you have a 163cc 550EX mower; Rakiyada's 799584 listing names that engine size and series.

A focused option for owners of a listed Toro Recycler 22 or compatible Toro walk-behind mower, with Craftsman 6.75hp applications also named. The engine and mower identifiers are the deciding fit boundary; this is not a universal carburetor listing.

#10

10. YzusGomumu 799584 Carburetor Kit

Best for: Carburetor and tune-up kit.

Why it ranks #10: The title identifies a 799584 kit with spark plug and air filter, but the supplied compatibility details name 09P602 engines, making the fit less clear.

The title pairs a carburetor with a spark plug and air filter, so this YzusGomumu kit brings three named replacement components together. Its listing also says the carburetor can address hard starting, oil leakage, poor acceleration and black exhaust smoke when those problems relate to the carburetor.

Having a spark plug and air filter named alongside the carburetor gives owners a broader set of listed service components than a carburetor-only title. The product description connects its carburetor kit with problems such as difficult starting, oil leakage, failure to accelerate and black exhaust smoke. Compatibility details include several 09P602 engine variants, including 0019-F1, 0039-F1, 0060-F1 and 0096-F1. Those specific codes provide a useful starting point for checking whether the kit matches a mower's existing engine.

Skip it if you need a 163cc 725EXi replacement; Rakiyada's 799584 listing specifically names that engine family.

Consider this kit if your mower matches one of its listed 09P602 variants and you want the title-listed spark plug and air filter with the carburetor. Its stated compatibility excerpt is narrow, so engine-code matching matters.
