After a wet spring, the back acre grows faster than the mower can keep up, and a rider that surges and stalls turns a Saturday mow into a weekend project. When the carburetor is the culprit, the best carburetor for riding mower is the one that matches the engine exactly. We compared five replacement carburetors by fit, kit contents and stated warranty, using only what each listing publishes.

Read the full review
TANG lists a carburetor for B&S 594601, 796587 and 591736, fitting 19, 19.5, 20, 20.5 and 21 HP Intek single-cylinder OHV engines on Craftsman riding mowers and tractors. The box includes a gasket and cleaning tools, and the spec table lists a 410 g weight with a bolt-on flange for gasoline. The listing promises a 30-day return or refund and a 6-month warranty with free replacements for quality concerns.
Pros
- Fits 19 to 21 HP B&S Intek single-cylinder engines
- Includes gasket and cleaning tools in the box
- 6-month warranty with free replacements for quality concerns
- Built to OEM standards per the listing, 410 g stated weight
Cons

- Cleaning tools are named but not described in the listing
- 30-day return window is shorter than the 6-month warranty
- No air filter included, unlike the Powtol kit
Czsmbt Carburetor for Troy Bilt Pony 42 Inch Riding Mower with Rebuild Kit
A direct-fit carburetor for the Troy Bilt Pony 42-inch rider with a full rebuild kit and seller service with refund or replacement.
Who it's for: Pony 42 owners who want every seal and gasket in one box.
Who should skip it: anyone with a different mower brand or engine.
Read the full review
Czsmbt lists a direct replacement for the Troy Bilt Pony 42-inch riding mower, matching the mounting holes, throttle cable interface and vacuum layout for 15.5 and 17.5 HP engines with no modification. The box is a complete tune-up kit: carburetor plus a full rebuild kit with gaskets, seals, fuel line and clamps. One oddity: the spec table lists the fuel type as Liquefied Petroleum Gas, which does not match a gasoline mower carburetor, so the bullets are the safer guide. The listing offers refund or replacement for any reason, without naming a warranty period.
Pros
- Direct fit for the Troy Bilt Pony 42-inch riding mower
- Full rebuild kit: gaskets, seals, fuel line and clamps included
- Seller offers refund or replacement for any reason, stated
- Covers 15.5 and 17.5 HP engines
Cons
- Spec table lists fuel type as Liquefied Petroleum Gas, odd for a gasoline mower part
- Troy Bilt Pony fit only, not for other mower brands
- Listing title has a typo in 'Engin' and sparse spec details
- No stated weight or dimensions

A complete 420cc tune-up kit carburetor for MTD-engine riders with stated mounting dimensions.
Who it's for: owners of a 420cc MTD-engine rider who want the full tune-up kit in one purchase.

Read the full review
Powtol lists a 951-05149 carburetor for MTD 4P90 420cc engines, fitting the Troy-Bilt TB30R, Cub Cadet CC30 and CC760ES, Craftsman T1000, T1200 and R1000, and the Huskee LT4200, among others. It is a complete tune-up kit: carburetor, air filter, fuel filter, a 2-foot fuel line, spark plug and 3 gaskets, with stated mounting dimensions of 51 mm hole spacing, a 26.8 mm throttle and a 30.4 mm choke. The listing is explicit about what it does not fit: 951-12771, 751-12771, 751-12823 and the small 1P61, 1P65 and 1P70 engines. No warranty term is stated.
Pros
- Complete tune-up kit: carb, air filter, fuel filter, fuel line, spark plug, 3 gaskets
- Fits MTD 4P90 420cc engines across many mower brands
- Stated mounting dimensions: 51 mm hole spacing, 26.8 mm throttle
- Clearly lists engines it does not fit (1P61, 1P65, 1P70)
Cons
- No warranty term is stated
- Long fitment list means confirming the exact model and year first
- No stated weight for the kit
- The wet-flow check is the maker's own claim, not a verifiable spec
sportuli 794572 Carburetor for Craftsman LT1000 LT2000, 14 to 20 HP
A 794572 replacement carburetor for Craftsman LT1000 and LT2000 tractors covering 14 to 20 HP.
Who it's for: Craftsman LT1000 or LT2000 owners matching the 794572 part number.
Who should skip it: anyone wanting a stated warranty or a full kit.
Read the full review
sportuli lists a 794572 carburetor for Craftsman LT1000 and LT2000 tractors and the DLS3500, covering 14, 15, 16, 17, 17.5, 18 and 20 HP Briggs & Stratton engines. The listing's tips note says the Nikki style with antibackfire solenoid is for 14 to 18 HP INTEK engines, which sits oddly against the title's 20 HP top end. The model number and part number fields just repeat the brand name, and no kit contents or warranty are stated. The flange is bolt-on with a machined finish.
Pros
- Fits Craftsman LT1000, LT2000 and DLS3500 tractors
- Covers 14 to 20 HP Briggs & Stratton engines
- Nikki style with antibackfire solenoid for 14 to 18 HP INTEK engines
- Machined exterior finish stated
Cons
- No warranty term is stated
- The tips note limits the Nikki solenoid version to 14 to 18 HP INTEK, while the title lists up to 20 HP
- Model number and part number fields just repeat the brand name
- No kit contents beyond the carburetor are stated
Carbhub 799728 Carburetor Replaces Walbro LMT 5-4993 for 10 HP Engines
A Walbro LMT 5-4993 replacement carburetor for 10 HP Briggs engines with a mounting gasket filter.
Who it's for: owners of a 10 HP Briggs rider matching the LMT 5-4993.
Who should skip it: anyone outside the listed part numbers or wanting a warranty.
Read the full review
Carbhub lists a 799728 carburetor replacing the Walbro LMT 5-4993 across a long list of part numbers, for 10 HP Briggs engines in the 282707 series and similar. The box includes a mounting gasket filter, and the flange is bolt-on. Two quirks: the manufacturer field reads 'Carbour' rather than Carbhub, and the listing also names a 9 HP Coleman generator engine, so confirm the mower fit before ordering. No warranty term is stated.
Pros
- Replaces the Walbro LMT 5-4993 across many part numbers
- Fits 10 HP Briggs engines in the 282707 series and more
- Mounting gasket filter included
- Bolt-on flange type stated
Cons
- No warranty term is stated
- Also listed for a 9 HP Coleman generator, so confirm it suits a mower
- Manufacturer field reads 'Carbour', not Carbhub
- No stated weight or kit beyond the gasket filter

How to choose the best carburetor for riding mower
Match the part number, not the mower
Every pick here is engine-specific. The TANG replaces B&S 594601, 796587 and 591736; the Powtol fits MTD 951-05149; the sportuli replaces 794572; the Carbhub replaces Walbro LMT 5-4993; the Czsmbt is built for the Troy Bilt Pony 42. Pull the number off the old carburetor first. See our riding mower maintenance guide for more upkeep parts.
Kit contents: gaskets, filters and fuel line
A bare carburetor is only half the job if the old gaskets leak. The Czsmbt box is a full rebuild kit with gaskets, seals, fuel line and clamps; the Powtol tune-up kit adds an air filter, fuel filter, a 2-foot fuel line, a spark plug and 3 gaskets; the TANG includes a gasket and cleaning tools; the Carbhub includes a mounting gasket filter. The sportuli listing names no kit contents. Compare air filters in our best air filter for riding mower roundup.
Warranty and returns
Only one listing states a warranty term: TANG offers a 6-month warranty with free replacements for quality concerns plus a 30-day return or refund. Czsmbt offers refund or replacement for any reason without naming a warranty period. The other three state no warranty term. Keep the old carburetor until the new one runs right.
Read the not-fit list
The Powtol listing names what it does not fit: part numbers 951-12771, 751-12771 and 751-12823, and the small-displacement 1P61, 1P65 and 1P70 engines. The Carbhub listing works the other way, with a long list of replaced numbers for the Walbro LMT 5-4993, from 799728 and 498027 through 699318, 699737, 699856 and 699896. The sportuli tips note narrows its Nikki solenoid version to 14 to 18 HP INTEK engines even though the title runs to 20 HP. When a listing gives two answers, trust the narrower one and confirm against the number stamped on the old carburetor.
Read the manual, keep children and pets out of the yard while you work, wear eye and hearing protection and sturdy footwear, and never exceed the slope rating of your machine. Refuel only with the engine off and cool. See CPSC lawn mower safety. Read our Safety Disclaimer.
Matching It to Your Property
- Match the part number to the engine before ordering: 594601-series, 951-05149, 794572, LMT 5-4993 or the Pony 42 fit.
- On rough ground that shakes hardware loose, the Powtol kit’s 3 spare gaskets cover repeat swaps.
- Store the leftover fuel line and clamps from the kit with the mower’s manual for the next service.
- Confirm the 51 mm mounting hole spacing on the Powtol against the old carburetor first.
The Acre Score explained
The Acre Score weighs performance, build, value, safety and warranty. For carburetors, performance means correct engine fit and complete kit contents, and safety covers stated fit warnings and not-fit lists. Two of the five state a warranty term. How we pick explains the weights.
| Product | Acre Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
|---|---|---|---|---|---|---|
| TANG 594601 Carburetor | 9.7 | 29 | 21 | 21 | n/a | 3 |
| Czsmbt Pony 42 Carburetor | 9.6 | 28 | 20 | 21 | n/a | 0 |
| Powtol 951-05149 Carburetor | 9.6 | 28 | 20 | 21 | n/a | 0 |
| sportuli 794572 Carburetor | 9.5 | 27 | 19 | 20 | n/a | 0 |
| Carbhub 799728 Carburetor | 9.5 | 26 | 19 | 20 | n/a | 0 |
Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score. Safety counts only for powered gear or where the listing states safety features; where it does not apply, the score is taken over the remaining 90 points.
FAQ: mowing large lots
How do I match a carburetor to my riding mower?
Read the part number off the old carburetor and match it to the listing: 594601-series, 951-05149, 794572, Walbro LMT 5-4993, or the Troy Bilt Pony 42 fit.
Which kit includes the most parts?
The Powtol tune-up kit: carburetor, air filter, fuel filter, a 2-foot fuel line, spark plug and 3 gaskets. The Czsmbt box is a full rebuild kit with gaskets, seals, fuel line and clamps.
Do any of these carburetors state a warranty?
TANG states a 6-month warranty; the other four listings state no warranty term.
Will the Powtol 951-05149 fit a small 1P70 engine?
No. The listing says it does not fit the 1P61, 1P65 or 1P70 engines, nor part numbers 951-12771, 751-12771 or 751-12823.
What does the 51 mm figure on the Powtol mean?
It is the mounting hole distance, center to center, stated in the listing, with a 26.8 mm throttle diameter and a 30.4 mm choke. Compare it with the old carburetor before ordering.
