The best riding lawn mower carburetor is the one that matches your engine and old part number, not just the mower's name. TANG covers several B&S replacement numbers, while the Pro Chaser L110 targets listed John Deere and Kohler combinations.

If the engine runs unevenly or won't start, confirm the fuel supply and carburetor fit before replacing parts. A wrong carburetor can create more repair work, even when the mower model sounds close.

For a broader comparison, see our guide to best lawn mower replacement carburetors. If you have a specific brand, the Craftsman carburetor options, Toro carburetor options, and Honda carburetor options narrow the choices by mower family.

How we chose riding lawn mower carburetors

The best riding mower replacements name the engines, mower models or part numbers they fit, and make package contents clear. We compared those fit details and included fuel-system parts, with the exact match taking priority over a long compatibility list.

The best riding lawn mower carburetors by fit

TANG is the strongest broad B&S pick here because it names several common replacement numbers. The other choices suit particular engine, Craftsman, John Deere, Troy-Bilt or MTD model references.

1

TANG Carburetor for B&S: Best for matching B&S part numbers

9.6/10Our score

• Replaces several B&S numbers including 594601 and 796587
• For listed 19 to 21 HP Intek single-cylinder OHV engines
• Gasket and cleaning tools included

The broad replacement-number range makes it a useful starting point for compatible B&S riding mower engines. Confirm the engine model and old carburetor number before buying.

See it on Amazon

Pros

• Several replacement numbers are named
• Gasket and cleaning tools included

Cons

• Compatibility still depends on matching the engine and part number

TANG is the first option to check when the old carburetor carries one of its listed B&S numbers. It names 594601, 591731, 796109, 594593, 796587 and 591736, along with 19 to 21 HP Intek single-cylinder OHV engines.

The package includes a gasket and cleaning tools. That can help when you're replacing the carburetor and want basic service items on hand, but compare the old unit and engine before relying on the broad range.

TANG describes the part as a replacement built to OEM specifications. That wording is the brand's claim, so use the part-number and engine match as the practical fit check.

Choose this for a riding tractor with a compatible B&S number. If the old carburetor number differs, check the engine's parts reference before ordering.

2

Pro Chaser L110 Carburetor for John Deere LT155: Best for listed John Deere and Kohler fit

9.5/10Our score

• Fits listed John Deere L110, LT155 and LT160 mowers
• Names Kohler SV530, SV540, SV590 and SV600 engines
• Includes fuel hose, clamps, valve, filter, wire, tie and spark plug

This option names several John Deere mower models and Kohler engines, with fuel-system parts included. Check the full model and engine number against its fit list.

See it on Amazon

Pros

• Multiple mower and engine models are named
• Includes several fuel-system pieces

Cons

• The long fit list needs careful model checking

Pro Chaser is a focused option for John Deere L110, LT155 and LT160 mowers with listed Kohler engines. The fit details name SV530, SV540, SV590 and SV600, along with several additional Kohler families.

This kit includes two gaskets, a fuel hose, clamps, a shut-off valve, fuel filter, connection wire, cable tie and spark plug. Check whether the included hose and connections suit your mower's fuel routing.

Because the fit list spans several mower and engine combinations, match the full mower model and engine code. If you have another John Deere mower, use its exact numbers rather than assuming the L110 fit carries over.

For a machine that is hard to use because of its seat height or controls, our guide to the best riding mower for seniors compares mower features beyond repair parts.

Toobop Carburetor For 42" Troy bilt pony: Best for listed Troy-Bilt Pony models

9.4/10Our score

• Lists six Troy-Bilt Pony and Bronco model numbers
• For listed B&S 15.5 HP and 17.5 HP, 500 cc engines
• Air, oil and fuel filters are described as included

The specific Troy-Bilt model list helps narrow fit for some Pony and Bronco mowers. Compare your mower number and air-filter appearance because the maker notes filter differences by serial number.

See it on Amazon

Pros

• Six mower model numbers are named
• Filter differences by serial number are called out

Cons

• Air-filter appearance should be checked before ordering

Toobop is aimed at specific 42-inch Troy-Bilt Pony and Bronco mower numbers. It lists six models, including 13WM77KS011, 13WN77BS011 and 13AN77KS211, and describes fit for B&S 15.5 HP and 17.5 HP, 500 cc engines.

The kit description includes a carburetor, air filter, oil filter and fuel filter. The brand also notes that air filters can differ by serial number, so compare the filter shape and mower details before ordering.

This is a practical choice when your mower model appears in its compatibility list. If the model is close but not exact, check the engine and serial number rather than relying on deck size alone.

SVKZGFZ 796587 Carburetor: Best for matching 796587 replacements

9.1/10Our score

• Replaces 796587 and several related numbers
• Lists multiple 19 HP and 19.5 HP Intek engines
• Package includes fuel filter, 2 clamps and gasket

This carburetor is centered on the 796587 number and related B&S references. Check both the old part number and carburetor appearance to confirm a match.

See it on Amazon

Pros

• Many related replacement numbers are named
• Basic installation parts are included

Cons

• The fit list requires checking the exact engine and part

SVKZGFZ centers on the 796587 replacement number and several related numbers, including 796250, 795486, 794136, 792768, 594605, 594601 and 591736. It also names various 19 and 19.5 HP Intek engine models.

The package includes a fuel filter, two clamps and a gasket. Its maker advises checking both the part numbers and appearance, which is useful because related engine families can use different carburetors.

Choose it when 796587 or a listed equivalent matches your old part. Compare the mounting and body shape before buying, especially if a previous repair changed the carburetor.

5

Pro Chaser LT1000 LT2000 Carburetor for Craftsman YT3000: Best for listed Craftsman mower families

8.9/10Our score

• Fits listed Craftsman LT3000, LT2000, LT1000, YT3000 and LT1500
• Names Nikki 795365 and related numbers
• Includes fuel filters, valve, hose, clamps and gasket

The mower-family names and Nikki numbers make this a targeted choice for some Craftsman riding mowers. The included solenoid should remain installed when replacing a similar carburetor.

See it on Amazon

Pros

• Several Craftsman families and Nikki numbers are named
• Includes fuel-line parts

Cons

• Confirm the old carburetor and engine before choosing

Pro Chaser targets Craftsman LT3000, LT2000, LT1000, YT3000 and LT1500 mowers with listed Nikki references. It names 795365, 795366, 792768 and 792036, and its fit details include several B&S engine families.

The kit comes with fuel filters, a shut-off valve, spark plug, clamps, fuel hose and gasket. It has a solenoid on the bottom; the supplied instructions say to leave it in place when using it to replace a similar model without one.

Match the mower family and engine model before choosing this carburetor. For more brand-specific options, compare our Craftsman riding mower carburetors, which are selected around Craftsman fit details.

6

Powtol 590399 Carburetor for Troy Bilt TB30: Best for TB30R 590399 replacements

8.7/10Our score

• 590399 replaces 796077
• Names Troy-Bilt TB30R model 13CC26JD011
• Lists several compatible B&S engine families

This is the narrowest match for a TB30R with the named model and replacement number. Check the mower model and engine family before selecting it.

See it on Amazon

Pros

• Replacement numbers are clear
• TB30R model number is identified

Cons

• Fit is specific, so it may not suit other TB30 versions

Powtol is a narrow fit for the Troy-Bilt TB30R with model number 13CC26JD011. It identifies 590399 as a replacement for 796077 and lists compatible B&S engine models.

Use this option when both the mower model and engine family line up. The compatibility list includes many engine codes, so the mower name alone is not enough to confirm fit.

If your TB30 has a different model number, check the engine's carburetor reference before ordering. This pick suits buyers who can confirm the 590399 or 796077 match.

7

laffoonparts 42 Inch Carburetor Carb: Best for listed Troy-Bilt Pony numbers

8.4/10Our score

• Lists several Troy-Bilt and MTD tractor numbers
• Names multiple B&S replacement part numbers
• Calls for model and part-number checks

This option lists several Troy-Bilt and MTD tractor numbers and a broad set of B&S references. Match your tractor model and old part number before ordering.

See it on Amazon

Pros

• Multiple tractor models and part numbers are listed
• Bolt-on flange

Cons

• The exact model and part number need confirmation

laffoonparts names a range of Troy-Bilt and MTD lawn tractor models, including Pony numbers, and lists numerous B&S replacement references. The fit details include 13WN77BS011, 13WM77KS011 and 13AN77KS211 among other variants.

The carburetor has a bolt-on flange and is described for gasoline use. The package contents are not specified, so plan to reuse suitable parts or source any gaskets and fuel-line items you need separately.

This is worth checking when your tractor model and old carburetor number both appear in the fit information. If only one matches, confirm the engine model first.

How can you match a replacement carburetor to a riding mower?

Match the engine model and carburetor part number first, then check the mower model against the replacement's fit list. Those details are more reliable than the mower brand or deck width on its own.

Look for a label on the engine and a stamped or printed number on the old carburetor. Compare the numbers carefully because similar engine families may use different fuel-delivery parts.

Also compare the carburetor's overall shape, mounting points and connections. A kit may include extra fuel-line parts, but those do not make an otherwise incompatible carburetor fit.

When should you clean a carburetor instead of replacing it?

Clean a carburetor when it appears intact and the issue may come from fuel residue or debris. Replace it when the body or a critical part is damaged, or when cleaning does not address a confirmed fault.

Drain old fuel safely and follow the mower and engine instructions before working on the fuel system. Our guide explains how to clean a carburetor on a lawn mower step by step.

Which replacement carburetor should you choose?

Choose TANG when your B&S carburetor number matches its listed range, Pro Chaser L110 for the named John Deere and Kohler combinations, and Toobop or laffoonparts when a listed Troy-Bilt model matches. For a Craftsman LT or YT mower, check the Pro Chaser Nikki numbers; for a TB30R, verify Powtol's 590399 or 796077 reference.

A replacement carburetor should match the engine and existing part before you weigh included filters, hoses or other extras. If cleaning may solve the issue, start with the cleaning guide before buying a replacement.

Frequently asked questions

How do I choose a riding lawn mower carburetor?

Start with the engine model and the part number stamped on the old carburetor. Then compare both against the replacement's fit list.

A mower brand alone is not enough because one riding mower line can use different engines or carburetors across years and model variants.

Can I choose a carburetor by mower deck size?

No. A 42-inch deck does not identify the engine or fuel system.

Use the mower's full model number and the engine model or carburetor number to check fit.

Deck size can help identify a mower family, but it should not replace a part-number check.

What parts may come with a replacement carburetor?

Kits vary. Some picks here include gaskets, fuel hose, clamps, filters, a shut-off valve or a spark plug, while others name fewer included parts.

Compare the package contents with the parts you need for the repair, and keep reusable parts only if they're in suitable condition.

Should I clean or replace a riding mower carburetor?

Cleaning may be enough when the carburetor is intact and fuel residue or debris is the likely issue. Replacement makes more sense when the part is damaged or you have confirmed a matching replacement.

Use our carburetor cleaning steps before deciding.
