6. Which lawn mower replacement carburetor should you choose?

The best lawn mower replacement carburetor depends on your engine model and original part number. The PSLER 799584 is a strong fit for several common small Briggs & Stratton engines, while Czsmbt targets Troy-Bilt Pony tractors and Ferilter covers selected Tecumseh engines.

A replacement carburetor can save time when cleaning or adjusting the old part no longer solves the issue. The right choice is the one that matches your engine and has the fittings your repair calls for, not simply the one with the broadest compatibility claims.

For a separate fuel-system component, compare lawn mower gas tanks. If you find fuel in the filter housing, see why gas gets in a mower air filter.

For a full repair package, compare the included gaskets, seals, fuel lines, clamps and filters. If you have a riding mower, our guides to the best riding lawn mower carburetor and best Craftsman lawn mower carburetor narrow the options by mower type.

Which lawn mower replacement carburetors match different engines?

The best lawn mower replacement carburetors

These picks are ordered by score, with compatibility and package contents guiding each recommendation. Our score weighs stated specs and features against what you're shopping for.

Czsmbt Carburetor Replacement for Troy Bilt Pony: Best for Troy-Bilt Pony tractors

9.7/10Our score

• For Troy-Bilt Pony 42 in riding mowers
• Fits stated 15.5 HP and 17.5 HP engines
• Includes gaskets, seals, fuel line and clamps

A direct replacement option for specified Troy-Bilt Pony tractors, with several common installation items in the package. Confirm the tractor and engine match before ordering.

See it on Amazon

Pros

• Includes fuel line and fixing clamps
• States no modification is needed for listed fits

Cons

• Fit is specific to listed tractor and engine combinations

Czsmbt is aimed at the Troy-Bilt Pony 42 in riding mower with a stated 15.5 HP or 17.5 HP engine. Its fit description calls out the mounting hole position, throttle cable interface and vacuum pipeline layout, which are useful details to compare with the original assembly.

The package includes gaskets, seals, a fuel line and fixing clamps. That makes it a more complete option for a repair where aged seals or a fuel line also need replacement.

This choice is narrow by design. Before ordering, confirm the Pony model, engine power and carburetor number; other tractor models from the same brand may use a different setup.

If the engine itself needs replacement, compare replacement engines for riding lawn mowers.

Choose it for the listed Troy-Bilt Pony combination when you want the replacement carburetor plus common sealing and fuel parts in one package. For other riding mower models, see the best Toro lawn mower carburetor guide for another brand-specific comparison.

2

TANG Carburetor for B&S: Best for larger Intek engines

9.6/10Our score

• Replaces several B&S part numbers
• For 19 to 21 HP single-cylinder Intek engines
• Includes gasket

This TANG carburetor targets a larger set of B&S Intek engines and names several replacement numbers. Check the engine's exact part number before choosing it.

See it on Amazon

Pros

• Several replacement numbers are specified
• For larger single-cylinder Intek engines

Cons

• Engine compatibility needs careful confirmation

TANG is the pick for a larger B&S Intek single-cylinder engine. It names 19 to 21 HP applications and replacement numbers including 594601, 591731, 594593, 796109 and 796587.

The package includes a gasket, but the details do not identify a larger fuel-line or filter bundle. That can suit a repair where you already have the needed fittings and want to replace the carburetor itself.

Use the engine's full model and original part number to confirm a match. For a Craftsman mower with a different engine family, the dedicated Craftsman carburetor comparison may be more useful.

Choose TANG when your engine number matches its listed Intek applications and a gasket is the main included extra you need.

3

PSLER 799584 Carburetor for Brigg and Stratton: Best for common 799584 replacements

9.5/10Our score

• Replaces 799584 and related numbers
• For several 550EX to 725EXi series
• Includes necessary gaskets

A broad fit list covers several common small-engine series and mower brands. Use the engine model and replacement number to confirm compatibility.

See it on Amazon

Pros

• Lists multiple engine series and mower models
• Gaskets are included

Cons

• Does not specify a full set of fuel fittings

PSLER's 799584 carburetor is the most broadly useful pick for common small gas mower engines in this group. Its fit list includes Briggs & Stratton 550EX, 625EX, 675EX and 725EXi series, with 140 cc, 150 cc and 163 cc engines among the stated applications.

It also names mower models from Troy-Bilt, Craftsman, Toro, Husqvarna, Yard Machines and Snapper. The package includes gaskets, but does not specify the range of extra fuel fittings found in some tune-up kits.

The long fit list is a starting point rather than a substitute for checking your model. Compare the engine code and the old carburetor number, especially if two engine versions share a mower model name.

Choose PSLER for a 799584 replacement when your engine series and replacement number align. Owners who have a Honda engine can use our guide to the best Honda lawn mower carburetor for brand-specific options.

4

Rakiyada 799584 Carburetor Fits 6.75-7.25HP 163cc Lawn: Best for 163 cc push mowers

9.4/10Our score

• For stated 163 cc, 6.75 to 7.25 HP engines
• Replaces several 799584 numbers
• Includes 2 rubber seals

This Rakiyada option is focused on 163 cc engines and names specific mower and engine models. It includes two seals, so check whether your repair also needs other fittings.

See it on Amazon

Pros

• Specific engine size and power range
• Replacement numbers are clearly identified

Cons

• Package has fewer listed accessories than a full kit

Rakiyada's 799584 replacement is a focused option for 163 cc, 6.75 to 7.25 HP engines. Its fit information names models such as Troy-Bilt TB110 and TB200, Craftsman M110, M220 and M230, and several Toro 09P702 variants.

It replaces several related numbers, including 592361, 594057, 594058 and 594529. The package includes two rubber seals with the carburetor, which is useful when the old seals need changing but you do not need a larger tune-up kit.

Check the complete engine model, not just the mower brand. If your mower runs but idles poorly after installation, review the steps in How to Adjust a Carburetor on a Lawn Mower? before changing any settings.

Choose this version for a confirmed 163 cc fit when the two included seals cover your needs.

5

LEIMO KPARTS 799868 Carburetor Compatible with Briggs: Best for primer type engines

9.2/10Our score

• For most 122000 model engines
• Fits listed 4 to 7 HP engines
• Includes primer base

LEIMO KPARTS names a wide set of Briggs & Stratton replacement numbers and includes a primer base. Check that your mower uses the stated primer type system.

See it on Amazon

Pros

• Broad replacement number list
• Primer base is included

Cons

• Fit depends on engine model and primer system

LEIMO KPARTS serves a different small engine setup, with compatibility focused on most 122000 model engines and primer type systems. It lists several Briggs & Stratton replacement numbers, along with selected Toro walk-behind mowers and 4 to 7 HP applications.

The package includes a 795259 air cleaner primer base. The maker describes the carburetor as pre-adjusted before shipping, though the engine model and primer arrangement still need to match your mower.

This is a better match for the specified primer system than for a generic gas mower repair. Compare your original part number and the primer base shape before selecting it.

Choose LEIMO KPARTS when your 122000 engine uses the stated primer type system.

6

Ferilter 640350 640303 640271 Carburetor for Tecumseh: Best for Tecumseh engines

9.0/10Our score

• For several Tecumseh LEV and LV engines
• Replaces 640350, 640303 and 640271
• Also names many Toro and Lawn-Boy mower models

This Ferilter carburetor serves a different engine family from the Briggs-focused picks. Compare the original carburetor number and images because several carburetors can fit the same Tecumseh engine model.

See it on Amazon

Pros

• Covers specified Tecumseh engines
• Names many compatible mower models

Cons

• Exact original carburetor number needs checking

Ferilter covers Tecumseh LEV and LV engines, including LEV100, LEV105, LEV120, LV195EA and LV195XA. Its replacement number family includes 640350, 640303 and 640271, and the fit information names selected Toro Recycler and Lawn-Boy mowers.

This option needs a careful part-number check because the same Tecumseh engine family can use different carburetors and air filters. Compare the number on your original part and the shapes shown for the replacement before ordering.

The product information does not give a complete accessories list beyond referencing the package contents shown with the item. Plan to reuse or source any fuel or sealing fittings that your repair needs separately.

Choose Ferilter for a confirmed Tecumseh number match, especially when your mower model appears in its stated fit family.

7

Rakiyada 799584 594058 Carburetor Kit Fits 163cc: Best for a broad tune-up kit

8.5/10Our score

• For specified 163 cc mower engines
• Includes fuel, air and ignition service items
• Lists several 799584 replacement numbers

This kit includes more than the carburetor, with fuel and air service parts plus a spark plug. Check the engine model and confirm which included items your repair actually needs.

See it on Amazon

Pros

• Broad set of tune-up parts
• Lists compatible engine and mower families

Cons

• May include parts you do not need for a carburetor-only repair

Rakiyada's full 799584 kit is the broadest tune-up package among these options. Along with the carburetor, it includes a spark plug, fuel hose, 593260 air filter, throat clamps, fuel shutoff valve, fuel filter, O-ring and gaskets.

Its fit list includes several Troy-Bilt and Briggs & Stratton small engine models and replacement numbers. That parts range can reduce separate sourcing for a multi-part service, but it is more than you need if the carburetor alone is the issue.

Before buying, compare the kit's engine list with your mower label and note which parts you already have. The extra components should match your repair plan.

Choose this kit when you need several fuel, air and ignition service parts together. If the carburetor is dirty rather than worn or damaged, our guide on How to Clean a Carburetor on a Lawn Mower? covers the cleaning route.

8

Carbhub Carburetor Replacement: Best for a parts-rich 122000 kit

8.3/10Our score

• For most 122000 model engines
• Includes air and fuel service parts
• Package includes primer bulb and clamps

Carbhub's package combines a replacement carburetor with several service parts. The available fit information is broader than a single mower model, so verify your engine and original carburetor number.

See it on Amazon

Pros

• Includes several fuel and air system parts
• Names 122000 model engines

Cons

• Exact compatible models require checking

Carbhub's replacement is packaged with a large set of common service parts for most 122000 model engines. The stated contents include an air filter, spark plug, fuel hose, fuel filter, shutoff valve, primer bulb, gasket with O-ring and six clamps.

That bundle can suit a repair where several connected parts need attention. Its fit details are less specific in the short compatibility summary, so use the full engine model and carburetor number to verify that it matches your mower.

The package is an aftermarket replacement. Check the original carburetor's connections and the engine's primer arrangement before choosing it over a more narrowly specified option.

Choose Carbhub when the included service parts fit your repair list and your engine matches its 122000 family.

9

Carbhub 791858 Carburetor Replacement: Best for specified Intek tractors

8.1/10Our score

• For listed 14 to 18 HP Intek engines
• Nikki style carburetor with antibackfire solenoid
• Names Craftsman LT1000 fit

This Carbhub pick targets certain Intek engines, including a specified Craftsman LT1000 fit. Check the engine type and solenoid arrangement before ordering.

See it on Amazon

Pros

• Names engine power range and carburetor style
• Includes several replacement numbers

Cons

• Fit is limited to the stated Intek configurations

This Carbhub carburetor is designed for selected 14 to 18 HP Intek engines and uses a Nikki style with an antibackfire solenoid. Its replacement numbers include 791858, 792358, 794572 and 799727, and the fit information names a Craftsman LT1000 with specified Intek motors.

The solenoid and carburetor style make exact matching important. Confirm your engine type, before-code configuration where relevant, and the original part number before ordering.

The available details identify air filter replacement numbers, but do not describe a complete fuel line or gasket kit. Check what you need for the repair before choosing this carburetor.

Choose it for the listed Intek setup when the solenoid and part numbers match. For easier starting and handling considerations beyond a repair, see Best Gas Mower For Seniors.

How do you match a gas lawn mower carburetor?

Match a gas lawn mower carburetor by engine model and the original carburetor number, then check the physical connections. Mower brands can use different engines and carburetor layouts across product lines.

Start with the engine label, which may show a model, type and code. Then compare the original part number, mounting pattern, throttle connection, fuel inlet and any primer or solenoid arrangement with the replacement's fit information.

A replacement number such as 799584 can help narrow the search, but it does not cover every engine. Confirm the full engine family and mower model before relying on a broad brand name or horsepower range.

If the mower is a riding model, use a dedicated comparison such as the best riding lawn mower carburetor guide. The engine family often matters more than the mower deck size.

Do you need a complete kit or just the carburetor?

A complete kit makes sense when your repair also needs fuel, air or ignition parts. A carburetor with gaskets or seals can be a better fit when the other parts are in good condition.

The Czsmbt package includes gaskets, seals, fuel line and clamps, while the PSLER package includes gaskets. The Rakiyada tune-up kit adds a spark plug, air filter, fuel filter, shutoff valve and other pieces.

Before choosing a kit, list the parts you plan to replace and compare them with what is included. A larger package may leave you with spare items, while a bare carburetor can require separate sourcing for fittings.

When should you clean or replace the carburetor?

Clean the carburetor when deposits appear to be the cause and the part is otherwise intact; replace it when cleaning does not resolve the problem or when components are worn or damaged. A replacement also makes sense if the carburetor body or connections are compromised.

Symptoms such as hard starting, stalling or weak running can have causes beyond the carburetor. Check fuel condition, air filter and ignition parts as well, and follow the engine maker's service instructions.

If you want to try cleaning first, follow the steps in How to Clean a Carburetor on a Lawn Mower?. After installation, use the engine-specific procedure before adjusting mixture or idle settings.

Which lawn mower replacement carburetor should you choose?

Choose the carburetor whose engine and replacement numbers match your mower, then use the included fittings to break a tie. PSLER suits a range of common 799584 applications, Czsmbt targets the stated Troy-Bilt Pony fit, and Ferilter covers selected Tecumseh engines.

For a focused repair, compare the carburetor and seals included. For broader maintenance, consider a kit with fuel and air parts, but confirm that each component fits your engine before ordering.

Frequently asked questions

How do I choose the right lawn mower replacement carburetor?

Match the engine model and the number on your original carburetor, then compare the mower model and fittings. A brand name alone is not enough because one mower brand can use different engines across models and years.

Check whether the package includes the gaskets, seals, fuel line or clamps your repair needs.

Can I use a gas lawn mower carburetor from another brand?

Sometimes, if the engine model and carburetor replacement number match. The mower's brand does not always identify its engine, so confirm the engine label and original part number before buying.

A carburetor listed for a similar horsepower or mower size may still have different mounting or fuel connections.

Should I buy a carburetor or a complete kit?

Choose a complete kit when you need several related service parts, such as a fuel hose, filter, air filter or spark plug. A carburetor with only gaskets or seals may be a better fit for a focused replacement.

Compare the included parts with your repair list to avoid paying for extras you will not use.

How can I tell if the carburetor needs adjustment after installation?

Follow the engine maker's instructions for your exact model. Some replacements are described as pre-adjusted, while adjustment procedures and screw layouts vary by engine.

Our guide on How to Adjust a Carburetor on a Lawn Mower? explains the checks to make before changing settings.
