Maintain the starting reliability and cutting performance of your Craftsman front tine garden tiller with genuine replacement parts from Repair Clinic. This 2010 model runs on a single cylinder, four stroke OHV engine built for residential soil cultivation, and most repairs on a machine like this come down to a short list of small engine components rather than anything structural. Whether you are chasing a hard start condition after winter storage, working through rough idle and stalling, or simply refreshing routine maintenance items ahead of spring planting, our inventory covers the carburetor, spark plug, ignition coil, air filter, and on/off switch assemblies this engine depends on most. Browse the complete Craftsman tiller parts catalog for every component built for this model, from gaskets and fuel lines to tine hardware and drive components. Repair Clinic also carries the smaller hardware items that tend to get overlooked, such as fuel filters, primer bulbs, recoil starter ropes, and drive belts, so a single order can cover everything a full seasonal tune up requires instead of piecing repairs together from several different suppliers over the course of a busy spring. Detailed parts diagrams and step by step repair guides are available alongside each listing, which makes it easier to confirm the exact component you are looking at before you add it to your cart and start the job.
About This Craftsman Front Tine Tiller
This machine, built around MTD engine 21AK144G799, is a gear drive front tine tiller from Sears’ 2010 lineup, sold under the Craftsman name during a period when Sears sourced most of its outdoor power equipment from MTD. Because of that shared manufacturing history, the engine architecture and many small engine components on this tiller have design roots in common with contemporary Troy Bilt and Yard Machines equipment sold during the same production years, even though the badging and cosmetic parts differ. Closely related revision variants from the same tiller family use the same basic engine platform but reflect minor running production changes made during the model year, such as updated wiring routing or a revised air filter housing, so it is always worth confirming your complete model and engine tag on the label, usually found near the engine shroud or on the tiller frame itself, before ordering an engine specific part such as a carburetor, ignition module, or starter assembly. Unlike two stroke trimmers and blowers, which require a premixed fuel and oil ratio measured out before every fill up, this tiller’s four stroke engine runs on straight gasoline and maintains its own separate engine oil reservoir on a change schedule set out in the owner’s manual. Keeping that oil change interval on track, alongside seasonal fuel system care such as draining or stabilizing gasoline before storage, is the single biggest factor in getting a long working life out of this style of front tine cultivator, well beyond what any single replacement part can deliver on its own. Homeowners who bought this tiller new in the early 2010s are now well past a decade of ownership, which typically means original rubber fuel lines, worn drive belts, and tired recoil starter springs are due for attention alongside the usual carburetor and ignition work, even on a machine that otherwise still runs sound. Working through these wear items methodically, rather than replacing everything at once, tends to be the most cost effective way to bring an older front tine tiller back to reliable service without overspending on parts that were not actually causing the problem in the first place. A quick visual inspection of the drive belt, tine shafts, and wheel hardware while the engine is apart for other work often turns up small issues before they turn into a bigger repair down the road.
Most Replaced Parts on the 316.29937
Carburetor Issues on the Craftsman 316.29937
A tiller that cranks but runs rough, stalls at idle, or refuses to start after sitting over winter usually points to a gummed up carburetor. Ethanol blended fuel varnishes internal fuel passages and hardens the diaphragm during off season storage, even in a garage. Before replacing the carburetor, confirm the air filter is clean and the fuel is fresh, since a restricted filter or stale gasoline can closely mimic the same rough running symptoms. Draining the float bowl before long term storage each fall goes a long way toward preventing the problem from recurring the following spring.
Spark Plug and Ignition Coil Problems on the 316.29937
When the engine cranks freely but will not fire, always start with the spark plug rather than the coil. Remove it, check the electrode gap and condition, and look for fouling caused by a rich fuel mixture from a dirty air filter. If the plug looks correct but spark is weak or absent at the boot, test the ignition coil next. Checking the plug first avoids paying for a coil that was never the actual problem, since fouled plugs are a far more common failure on this engine than a genuinely bad coil.
Air Filter Replacement for the 316.29937
A clogged air filter restricts intake airflow, forcing the engine to run rich and burn fuel inefficiently. Typical symptoms include black exhaust smoke, noticeably reduced power while tilling under load, and hard starting on cool mornings. Inspect and clean or replace the filter element before adjusting or replacing any carburetor components, since a dirty filter is a far more frequent root cause of poor running than an actual carburetor fault. A fresh filter each season keeps the fuel mixture correct and reduces long term wear on internal engine parts, extending the interval between more expensive repairs.
On/Off Switch and Starting Circuit for the 316.29937
If the engine will not start at all and shows absolutely no sign of trying to fire, test the on/off switch for continuity before condemning the carburetor or ignition coil. A switch stuck in the off position, or one with corroded internal contacts, interrupts ignition entirely and can easily be mistaken for a more involved engine fault by a first time troubleshooter. Confirming the switch early in the process shortens the overall diagnostic path considerably and saves needless part swapping on parts that were never actually at fault.

316.29937 Parts FAQ
What kind of engine does this Craftsman tiller use?
It is a front tine, gear drive garden tiller built in 2010 around a single cylinder, four stroke OHV engine designed for residential soil cultivation, edging along garden beds, and light seasonal yard prep work around the home.
Why won’t my tiller start after winter storage?
Hard starting is most often caused by stale or ethanol varnished fuel sitting in the carburetor over the off season. Check the air filter and spark plug first, then inspect the carburetor and fuel lines if it still will not fire reliably.
How is this model different from other similar Craftsman tillers?
Closely related revision variants share the same basic engine family but reflect small running production changes made during a given model year. Always confirm your complete model number and engine tag before ordering an engine specific component to avoid a mismatched part.
How often should this tiller be serviced?
Clean or replace the air filter each season, inspect and gap the spark plug annually, and drain the fuel system or add a stabilizer before winter storage to keep the carburetor free of ethanol varnish buildup between uses.
