The best Craftsman lawn mower engine replacement depends on the engine model and the failed part. The products here are replacement or maintenance parts for selected engines, not complete engines, so identify the engine and match part numbers before you buy.
A Craftsman mower may use an engine from Briggs & Stratton or another manufacturer, and the brand name alone does not identify every replacement part. For a full engine swap, check the original engine’s output, crankshaft dimensions, mounting pattern, controls and exhaust connection against the replacement.
If you need a complete engine rather than a repair part, compare our guide to the best lawn mower engine. Owners of riding mowers can also review best riding lawn mower engines and best riding lawn mower mufflers for related replacement decisions.

STP Premium Synthetic Blend 4 Cycle Small: Best for routine oil changes
- SAE 10W-30
- Synthetic blend
- 32 fl oz bottle
- For small 4-cycle engines
A small-engine oil option for a mower whose manual calls for SAE 10W-30. Check the manual for the required oil grade and change interval.
Pros
- Made for small engines
- 32 fl oz bottle
- Antioxidants and detergents
Cons
- Only suitable when the engine manual permits this oil grade
STP’s 10W-30 synthetic blend is the oil choice here for a Craftsman engine whose manual calls for SAE 10W-30. The 32 fl oz bottle is made for small engines in equipment such as lawn mowers, generators and tractors.
STP says its antioxidants help fight thermal breakdown, while detergents help control carbon deposits. Those features do not override the engine maker’s oil requirements, so check the manual for the right grade and service schedule.
This is routine maintenance, not an engine replacement. If the engine has low compression, internal damage or another serious fault, new oil alone will not restore it.
Ferilter 799868 Carburetor For Briggstraton: Best for listed 6.5 to 6.75 HP engines
- Carburetor replacement
- References 799868 and other part numbers
- Includes air filter and related parts
A carburetor kit for listed Briggs & Stratton engine and part numbers. Verify the mower's engine model and existing part number before ordering.
Pros
- Lists multiple replacement part numbers
- Includes an air filter and small installation parts
Cons
- Compatibility depends on matching engine and part numbers
Ferilter’s 799868 carburetor is aimed at listed Briggs & Stratton engines in the 5.5 to 6.75 HP range. The fitment details include several engine model families and replacement numbers, including 498170, 799868 and 799872.
The package includes an air filter, spark plug, O-ring, gasket, grommet, air cleaner base and springs. That makes it a broader repair kit than a carburetor alone, but the number of listed applications is a reason to check your exact engine code carefully.
Use the carburetor number from the old part and compare it with your engine model. A 6.5 HP label or Craftsman branding by itself is not enough to confirm a match.
TRIAX Power 4-Stroke 10W-30 Full Synthetic 4-Cycle: Best for full synthetic 10W-30
- SAE 10W-30
- Full synthetic
- 32 fl oz bottle
- For small 4-stroke engines
This full synthetic oil is an option when a Craftsman engine manual specifies a compatible 10W-30 grade. Check the manual before choosing oil.
Pros
- Full synthetic formula
- For small 4-stroke engines
- 32 fl oz bottle
Cons
- Use only if the engine manual allows this viscosity
TRIAX offers a full synthetic 10W-30 oil for small 4-stroke engines. It can suit a Craftsman mower when its manual calls for this grade and oil type.
The 32 fl oz bottle is also described for generators, tractors, log splitters and other small engines. TRIAX says the formula is designed for high loads and a wide temperature range, but your mower’s manual remains the guide for viscosity and change intervals.
Choose between this and the STP option based on the oil type specified by the engine maker. The two oils share an SAE 10W-30 grade, but one is full synthetic and the other is a synthetic blend.
TANG Carburetor for B&S: Best for listed riding mower engines
- Carburetor replacement
- References B&S 594601 and other part numbers
- For listed 19 to 21 HP engines
A carburetor option for certain single-cylinder B&S engines used in riding mower tractors. Match the engine and carburetor numbers before buying.
Pros
- Lists several replacement part numbers
- For selected riding mower engines
Cons
- Does not fit every Craftsman riding mower
TANG’s carburetor targets selected B&S single-cylinder engines in the 19 to 21 HP range, often found on riding mower tractors. Its listed replacement numbers include 594601, 796587 and 591736.
This part is not intended for every Craftsman walk-behind mower. The engine family and carburetor number matter more than the mower’s paint, deck size or brand badge.
Compare the original carburetor number and the engine identification code before ordering. For other engine replacement considerations on a riding mower, see our guide to best riding lawn mower engines.
Kacarber M230 Air Filter Tune Up Kits: Best for Craftsman M230 tune-ups
- For Craftsman M230 163cc mower
- Two air filters
- Includes spark plug and fuel-system parts
A tune-up kit for the specified Craftsman M230 engine. It does not replace the engine, but can supply several routine service parts.
Pros
- Names the M230 engine
- Includes two air filters
- Includes several tune-up components
Cons
- Confirm the mower model and engine number
The Kacarber kit is specifically described for the Craftsman M230 163cc 11A-B2A9791 mower. It includes two air filters, a spark plug, fuel filter, fuel shutoff valve and air-cleaner parts.
This is a tune-up kit, not a new engine. It can be useful when you want several named service parts for the M230 in one package, provided your mower matches the stated model and engine.
The kit also lists compatibility with several other engines and mowers. Check the full model information rather than assuming that every 140cc or 163cc engine takes the same filters.
Hutdkte 675 190cc Carburetor for Craftsman Gold: Best for listed Quantum engines
- Carburetor replacement
- For listed 675 and 725 series engines
- Includes air filter and related parts
This kit names selected Craftsman Gold and Quantum engine applications. Check the model and type code against your mower before ordering.
Pros
- Names several engine and mower applications
- Includes an air filter and spark plug
Cons
- Long fitment list makes model-code checking essential
Hutdkte’s carburetor kit is for selected Quantum engines and names Craftsman Gold mower applications, including certain 675 and 725 series engines. It includes an air filter, spark plug, fuel hose, fuel filter, shutoff valve, primer bulb, gasket and springs.
The broad list covers many engine and mower codes. Use your engine’s model and type information to confirm the fit, especially if the old carburetor has a readable number.
This may be a reasonable repair part when a matching carburetor is the problem. It will not address unrelated causes of hard starting, such as an ignition fault or a seized engine.
Xingehor 593872 595009 Ignition Coil for Briggs: Best for matching ignition coil numbers
- References 593872 and 595009
- For listed Briggs & Stratton engines
- Includes spark plug
An ignition coil option for selected engines when the mower's model, type and code match. Confirm those codes and the replacement number first.
Pros
- Lists several replacement numbers
- Names selected engine series
- Includes a spark plug
Cons
- Compatibility depends on matching the engine model, type and code
Xingehor’s ignition coil lists replacement numbers including 593872 and 595009, with applications for selected Briggs & Stratton 08P502, 09P602 and 09P702 engines. It also includes a spark plug.
The fitment instructions call for checking the engine model, type and code. Do that before buying because several Craftsman, Troy-Bilt and MTD machines may use different engines even when the mower brand is the same.
If the mower cranks but does not start, a coil is only one possible cause. Confirm the ignition fault and match the replacement number before replacing parts.
How do you match a replacement part to a Craftsman engine?
Match the engine’s model information and the old part number before choosing a replacement. For a complete engine, also compare the physical dimensions and connections.
Start with the engine label or stamped code. Record the model and type, plus the code if present, and then compare them with the application details for the part.
If the old carburetor or coil has a part number, use that as another check.
For a complete engine swap, measure the crankshaft diameter, usable shaft length and keyway, then check the mounting bolt pattern and orientation. Confirm the output, throttle and choke controls, fuel connection, exhaust and any charging connections match the mower.
For a related fuel-system replacement, compare lawn mower gas tanks.
Avoid choosing by horsepower alone. Two engines with similar output may have different shafts or mounting layouts, making one unsuitable for the mower.
When should you replace an engine instead of a repair part?
Replace a repair part when you have identified a failed component and verified the replacement fit. Consider a complete engine only after checking whether the rest of the mower is in suitable condition and whether the replacement matches the chassis and controls.
A carburetor may be the relevant repair when fuel metering is the problem, while an ignition coil is relevant when spark is absent and the coil is confirmed faulty. A filter or oil change covers maintenance needs, not internal engine damage.
If the engine will not turn, inspect for an obstruction or other cause before deciding it needs replacement. Our guide explains how to unseize a lawn mower.
For overheating symptoms, see why a lawn mower engine overheats.
What should you check before ordering a Craftsman engine part?
Check the part number, engine model and included components before ordering. A matching label on the mower alone is not enough when the replacement is specified for a particular engine family.
For carburetors, compare the existing part number, mounting points and connections. For an ignition coil, verify the engine model, type and code.
For a filter kit, make sure the mower and engine identifiers match the stated application.
For oil, follow the engine manual’s grade and change interval. If you are comparing engine brands, our overview answers are Honda lawn mower engines good.
Which Craftsman lawn mower engine option should you choose?
Choose the STP or TRIAX oil only when your manual calls for SAE 10W-30, and pick between them by the specified oil type. Choose a carburetor, ignition coil or filter kit only when its part number and engine application match your mower.
For a complete engine swap, measure the shaft and mounting pattern and verify controls and connections before buying. The best Craftsman lawn mower engine replacement is the one that matches those details and the repair your mower actually needs.

Frequently asked questions
Are these complete replacement Craftsman lawn mower engines?
No. These picks are maintenance and repair parts, such as carburetors, an ignition coil, air filters and oil.
If the engine itself needs replacement, identify the mower and engine model first, then compare complete engines by shaft dimensions, mounting pattern, output and other fit requirements.
How do I find my Craftsman mower engine model?
Look for the engine identification label or stamped model information on the engine, then record the model, type and code where available. Use those details to check the replacement part numbers and fitment.
The mower's Craftsman model number can help, but engine codes are often needed to confirm a part.
Can I use 10W-30 oil in a Craftsman mower?
Use 10W-30 only when the engine manual permits that grade for your conditions. The STP and TRIAX options here are both SAE 10W-30, but the correct oil and service interval depend on the specific engine.
Check the manual before filling or changing oil.
How do I know which carburetor fits?
Match the carburetor's part number and the engine model, type and code. Similar horsepower or a shared mower brand does not confirm fit.
Compare the mounting and connections with the old part, and check the listed engine applications before ordering.
Should I replace an engine or repair it?
Repair may make sense when a specific service part has failed and the engine otherwise suits the mower. A complete replacement requires checking shaft dimensions, mounting pattern, output and control connections, then comparing those details with the mower.
If the engine is seized, investigate the cause before fitting parts.
